Young man that information was absolutely fantastic. I've looked everywhere on here to try to find someone simple but yet precise and you are it. I am a new denture with a very inexpensive telescope it is a 700 mm by 40 mm and it came with a 25 mm IPS as well as a 10 mm IPS the same exact ones youwhen I remove my diagonal reflector I can't
@@jami6600 Young Man you don't need to Waste Your Hard Earned Money for a Nother Telescope. ALL You Need is a Descent Angle lense. Also you should get a 2x Barrel for around 20 and get 3 eyepieces a 15mm a 25mm and a 40 mm you can find them Almost New on OfferUp and Craiglist Total cost is around 30 to 50 no more than that. you should make sure you have the angel piece In the right direction
Allen is great. But I'd say John Dobson was the Bob Ross of Telescopes. Just watch his "come see the moon" video on RUclips and you will know what I mean
Very well done. Just as a side note, I use a 55mm-2” eyepiece for a very wide field of view. A similar wide field can be obtained from a 40mm-1 1/4” eyepiece. Wide fields mean any planets will look small with very little detail, but extended objects like galaxies and wide nebulae will fill your field of view in dark skies. My choices for focal length are 55mm, 40mm, 24mm, and 16mm.
I had a 28mm eyepiece and i really recommend it since you can get a big image and decent magnification of moon and jupiter (it's still very small but you can see it as a whole system)
This is outstanding!!! My father ground his own mirrors & fabricated all of his telescopes, which I used as a kid. I grew up loving to look at the stars. But now, I only have a small Meade scope, with eyepieces that I got from a friend. I had no idea how use those - now I do! Thanks greatly for your video!!
I have saved this video to watch again later. I have just bought a 12" Dob GoTo as my first Telescope, so the infor you have given here is gold. yes it came with two eyepieces as you say. I was thinking about what I would grauate to later on and what to avoid doing. but how is that mate, people are still watching your video from three years ago! cool stuff. cheers!! clear skies!
Excellent, informative and well presented video Allan. :)) I have a Nexstar 130 telescope, and as a complete novice it has taken me 3 nights just to get the skyalign correct (I am based in the UK). I did not realise till today that I can increase the magnification of each eye piece, to further increase the accuracy of my sky align (I used a 25mm eye piece last night). Looking forward to doing this tonight, we are 29 degrees in the uk today with clear sky’s and zero wind. :))
Great channel, very well explained. Basically, I’d go for a 15 mm and a 24 mm high end eyepieces + a high end barlow x2 and that’s quite enough for > 90% my needs
This is a GREAT video! Comprehensive & concise, this covered all the questions I had! :D I have an old Meade 4500 that I got when I was a kid & honestly I think I was too little at the time to appreciate & understand what a complex device I had been gifted. I still had fun with it, & saw some cool things, but it was a bit confusing for 10yr old me. Luckily, I'm older now & still have it (and it still works great!) so now I'm having fun learning about it all over again! Now I can go out, well informed, & buy my first set of eyepieces! Thank you so much!!
Who dislikes this video? I want real answers. it just baffles me when people dislike videos.unless it offensive or whatever . I viewed this one and thought it to be very informative that could be very helpful to any beginner. Really people?
Unreal right?? I've watched quite a few videos on astronomy in the last few days and was wondering why people disabled comments on a lot of the amateur videos....this was so informative for me and to think someone would trash this guy for making a great video....why are people so angry now a days??
Beautiful back yard! My scope cane with a 25mm and a 6mm (both pretty low quality optics IMO). I can get the 6mm to focus on the moon, even woth a 2x barlow but that's about it.. I almost always use the 25, amd throw on a 2x barlow pretty regularly also... The zoom is so extreme at that level, it's hard to even keep objects in the field of view, you'll be chasing them the whole time... it's kinda fun for a second but not relaxing or very enjoyable for long... I also always wear my 3x or3.5x reading glasses, but can't with the 6mm due to eye relief... theyre no issue with the 25mm.. I think I'm gonna buy a 10 or 12mm and a 30+ mm and another 2.5x barlow to upgrade/supplement the cheapo starter stuff that came with the scope.
Cheers mate, after watching so many vids etc..on eye pieces i was totally confused as a newbie, your video answered all my questions and now i will go and get the correct eye pieces, once again thanks for the insightful vid!
Thanks dude. You are the best for beginner understanding we have found. One last request. Please show connection and combinations of the lenses to the telescope itself. Ours came with 10 lens components and no instructions. We are stumped. Some look lie the go together . some have no lens... And one loose piece of glass looks like a splitter or angle... But not in a screw on device . its a Meade ETX 90
I wish I had watched this video before I bought a 4mm, 10mm, 25mm, and a barlow from amazon. It cost me about $53 so it wasn't a total waste of money. I like the idea of the "eye relief" lenses. I wear glasses and it's a real pain trying to use the, let's call them budget-friendly lenses. I need to save up to get those larger eyepieces. I bought a Celestron - NexStar 4SE Telescope - Computerized Telescope. I really like the telescope as I have been able to find things in the sky. I have two other non-computerized telescopes gathering dust in my bedroom because I could never figure out how to see anything other than the moon. With the Celestron, I have been able to see the rings of Saturn and the band on Jupiter with the 25mm lens that came with it. My next goal is to figure out how to take pictures of what I see. I have bought the adapters but I haven't had any luck getting good pictures. Unfortunately, the best viewing for me, I live in New Hampshire is during Winter but the cold is not conducive to comfortable astronomy or astrophotography.
Thank you for this informative video. Im a bit new to my telescope, it came with a 25mm. I also got a kit of additional eyepices and a barlow, that has a 6mm, 8mm, 13mm, 17mm, and a 32mm. For fun i tried to use the 6mm on the moon and thought i was doing something wrong, i could not get a clear view no matter what. I will just stick to the 25, 17, and 13.
Quick rule of thumb: Best contrast will happen when the eyepiece focal length is double the telescope focal ratio. Highest USEFUL magnification happens when eyepiece focal length equals the telescope focal ratio. Example: If using a 8-inch telescope with a 1250mm focal length. ( focal ratio of 6) Highest useful magnification is achieved at 6mm (208x), best contrast at 12mm (104x).
Great rule of thumb! Just remember that you are factoring in only the telescope specifications which tell just a part of the story. Under really great skies you could push your example a smidge to maybe a 4mm (would appear roughly the same as a 6mm under average skies) but most likely for most people, a 6mm would be too much power for their location. Contrast is of course dependent on other factors too such as if the mirror is acclimated fully, the coatings on an eyepiece (my Naglers have far more contrast than my Celestron x-cels for example), and the telescope type (a 4” refractor will almost always have more contrast than a 4” reflector). Still. Great info, thanks!
@@AllanHall I agree, there are times when sky conditions and other factors allow for higher magnification. However, 85-90% of the time, exit pupil diameter of 1mm gives "best". Typically, a person only needs 3 eyepiece. Lowest, "sweet spot" and Highest practical.
Nice easy to listen and understand. I've got a celestrion 130eq coming today £219 not my first telescope yet 1st to have motor mount also have a newtonian scope.. have never researched eye pieces, now I'm interested in the 2inch.. I think I've waited long enough for an upgrade...
a thing i noticed with the higher magnification lenses is that they actually require the sharpness setting to be different even when looking at the same object (not sure if this is just because of the telescope i use) and if you get the sharpness to be better for the lens the object you are looking at seems to be sortof a little bit darker but it still becomes pretty clear from my experience however it also might be dirty and need cleaning as higher magnifications appear to be more sensitive to dirtiness the eyepeice i use is a sr4mm and while i havent tried looking at saturn yet i have tried looking at the moon and some stars that all appear to get more clear however as said i dont know about planets like saturn yet
Excellent advice and well explained basics of telescope eyepieces. I myself have a 30mm, 17mm, 12mm and a tele-extender. These handle cover everything. Nice job with the video.
Great video with lots of needed info for me. Im waiting for my first telescope to come and i was nervous about wasting time or money not knowing much about the lenses and centering the mirrors as im told ill need to do on occasion. Thanks for taking the time to explain things so clearly!
Hey Allan I'm stuck trying to decide what telescope to get Celestron Nexstar 8se or SkyWatcher Dobsonian 10" without the Go To , I am a complete Newbie, just want to look up and see some planets and Nebulae with good definition views ,not thinking of astrophotography ,I have $1300 to $1600 to put in it ,what would you suggest ? Type of telescope, eyepiece, barlow ,Focu reduction, etc. Thanks .
The thing that took me the longest to understand is the relationship between focal length and field of view.. can make 2 very different focal length eye pieces seem very similar. If an eye piece with a less focal length has also a less fov, it will be similar in appearance to the longer focal length with wider fov.. This is where preference comes in.. I very quickly decided, the long focal length with the wide fov is way freakin better. It's immersive. It pulls your perception into the sky, it makes you feel like you aren't looking in a telescope, you're looking out a spaceship window. So those are the 2 biggest things to consider in my mind.. You have to consider a 3rd if you are sharing the telescope with a 4 eyed person or if you plan on showing the sky to strangers or family.. You need an eyepiece or 2 with decent eye relief. This means the eye can travel a distance from the lens and the image is still apparent. 20mm or more is ideal.
Thank you for this video. I needed some basics for picking out eye pieces for a new Celestron 6Se. I just wanted someone to tell me what they low, mid, and high tiers were so I could make a semi informed decision.
Thanks for such a nice video - if only I had watched your video a couple of years earlier, I would not have bought so many eyepieces. I ended up spending money on 25mm, 10mm, 4mm along with a 2x barlow - all these being in addition to 30mm and 9mm that came bundled with the telescope! Anyhow, want to know from you if it would be worthwhile to buy a 24mm - 8mm variable power eyepiece. Would be a great help if you can help make a decent selection. Thanks in advance.
Sir I did just what you said in the beginning of this video. Buying all these eye pieces and still can't see. Thank for this video. I have learned a lot.
Great video . My 4 year old has taken a keen interest in telescopes an I got him his first one the other week but it's something I know very little about so your video has helped us out a lot...👍👍👍
Thank you! Great explanation! I have a reflector with 150mm aperture and 1200mm focal length, which uses 1.25' eyepieces. I have 25, 20 and 10mm eyepieces and a 2x Barlow. When I use the Barlow with the 10mm eyepiece it gets harder to focus, especially on distant objects like Saturn. The tiniest touch to the focuser shakes the image. I guess 3x Barlow would amplify those effects and would be even harder to focus? I'm wondering if it's worth buying a 3x Barlow, because I want to get a better view of Saturn or should I invest in better quality eyepieces, because the ones I have are of the cheap kind?
The shaking and difficulty getting the image in sharp focus will indeed get harder with a 3x barlow, it will also degrade the image more than a 2x barlow. Better eyepieces will help your enjoyment quite a bit but there is no need to get too crazy. Try a amzn.to/2Ijv4Ig to use without a barlow, and a amzn.to/2XpE7jD to use with a barlow. The 5mm without a barlow will have a better image than your 10mm with a barlow, plus better eye relief and probably a slightly wider field of view. Remember that seeing conditions matter more than eyepieces and how comfortable you and your eye are at the telescope can make a world of difference. Clear skies!
thanks ! Clear up some confusion for me for sure. I see there are zoomable 8-24mm eyepieces out there. Would that be a better choice than multiple eyepieces ?
So quick question, those larger eyepieces will fit into a 1.25” and will also have the larger field of view on the other end where you look through? So does that effectively convert a 1.25” situation into a 2”? Or is there a downside to doing that conversion? I’m really new to this so sorry if that’s a silly question.
I found a old Montgomery ward telescope in closet. Needs cleaned. And needs eye piece ordered one. Hoping it comes so I can clean it up and check it out
Great vídeo straight to the point. One question: do you think a 10 inch is worthwhile when compared to an 8 ? Mobility is not an issue. I am just wondering If the image improvement worth the extra money. Thanks Allan. All the best
This was the video I needed to watch! Thank you! I have a question. Last night I found Jupiter using my 25mm and 10mm lens and it looked the same using both eye pieces. Am I doing something wrong? I thought the 10mm would bring Jupiter much closer to me? Just subbed to your channel and am going to binge watch and learn. Thank you!
The 10mm should make the image larger, but it will also make it a little less sharp. If both seem to show the same size image, then I would say something is wrong. See if there is a local astronomy club in your area and ask to borrow a couple of inexpensive eyepieces to test. You might have one that is mislabeled or just bad.
Great video , its helped me understand alot more , i do have one question, what is your view on lenses thats can be adjusted from 7mm-21mm are they any good or a waste of time ?
Thanks for the video, but do we need to know if these are Huygens, Plossl, Kellner, etc? BTW, the beginner scope I have has 0.965" diameter pieces and I wear glasses so will definitely be looking to upgrade.
Very informative. Thank you for sharing your knowledge. I've had a reflector telescope for years and only used it twice to look at the moon. I'm hoping to get some good pictures of the Neowise Comet. Wish me luck.
I would appreciate an update on some of the barlows and lenses I currently have a c8 Celestron that I've built from trash I got it up to working condition I really would appreciate an update and links to where we can get the most cheapest barlows and lenses
Great Video, definitely going to check out the Orion Stratus. I have a AWB 5" reflector made by Celestron.. 650mm focal length, came with two beginner eyepieces, 10mm & 25mm kellner. I really want that wider field of view, do you think a 68 degree eyepiece will do or should I look at say a Celestron Luminos which is 82 degrees. Thanks for the help!
I think how wide a field of view a person prefers is a very personal thing and there is no right answer to it. Each person also might view the optical quality differently as they are more bothered by one type of optical imperfection than another. That being said... My opinion is that the Stratus eyepieces are better optically than the Luminos eyepieces and the ability to use them in both 2” and 1.25” applications is a really nice addition. Those qualities would outweigh the wider field of view of the Luminos for me. I do enjoy my 82 degree Naglers but that is a combination of the wider field of view and the amazing optics in these things. There is something to be said for what appears to my eyes as optical perfection from one edge to another. That is something I had never had in an eyepiece before the Televues. The real truth in this conversation is that no matter which you go with it will be such a huge improvement over those Kellner eyepieces you have now that it might not matter at all. Whatever way you go let me know what you did and what you think of your decision after the fact, love to get new opinions!
Hello Alan, Thanks for the information. I am definitely leaning toward the Orion Stratus eyepieces, the 68 degree field of view compared to what I am using now (probably 45 to 50) I am sure will be a huge improvement, I prefer a wide field of view. I will keep you posted on what I end up getting & what my viewing experiences are. Thx!

I ended up spending money on 25mm, 10mm, 4mm along with a 2x barlow - all these being in addition to 30mm and 9mm that came bundled with the telescope! Anyhow, want to know from you if it would be worthwhile to buy a 24mm - 8mm variable power eyepiece. Would be a great help if you can help make a decent selection. Thanks in advance.
Sir I did just what you said in the beginning of this video. Buying all these eye pieces and still can't see. Thank for this video. I have learned a lot.
Great video . My 4 year old has taken a keen interest in telescopes an I got him his first one the other week but it's something I know very little about so your video has helped us out a lot...👍👍👍
Nicee
Great video. Could you go into details of color and wideband filters and what their applications are ?
Hi Allan, just found your channel and subscribed. Great explanation of the basics of EPs. Clear skies, Graham
Thank you! Great explanation!
I have a reflector with 150mm aperture and 1200mm focal length, which uses 1.25' eyepieces. I have 25, 20 and 10mm eyepieces and a 2x Barlow. When I use the Barlow with the 10mm eyepiece it gets harder to focus, especially on distant objects like Saturn. The tiniest touch to the focuser shakes the image. I guess 3x Barlow would amplify those effects and would be even harder to focus?
I'm wondering if it's worth buying a 3x Barlow, because I want to get a better view of Saturn or should I invest in better quality eyepieces, because the ones I have are of the cheap kind?
The shaking and difficulty getting the image in sharp focus will indeed get harder with a 3x barlow, it will also degrade the image more than a 2x barlow.
Better eyepieces will help your enjoyment quite a bit but there is no need to get too crazy. Try a amzn.to/2Ijv4Ig to use without a barlow, and a amzn.to/2XpE7jD to use with a barlow. The 5mm without a barlow will have a better image than your 10mm with a barlow, plus better eye relief and probably a slightly wider field of view.
Remember that seeing conditions matter more than eyepieces and how comfortable you and your eye are at the telescope can make a world of difference. Clear skies!
thanks ! Clear up some confusion for me for sure. I see there are zoomable 8-24mm eyepieces out there. Would that be a better choice than multiple eyepieces ?
Very nicely explained, this is a very informative video and your advice made an awful lot of sense to me, thank you.
So quick question, those larger eyepieces will fit into a 1.25” and will also have the larger field of view on the other end where you look through? So does that effectively convert a 1.25” situation into a 2”? Or is there a downside to doing that conversion? I’m really new to this so sorry if that’s a silly question.
Thank you. Very clear audio and concise explanations! Much appreciated.
can tell you're trying to cover as much as possible, thanks for the video :)
thank you for your video, im not getting into this whole telescope stuff, since I got one as a gift for Christmas
Thanks for the break down Allan. I have 2 lenses and a 2X Barlow and decided to try a telescope zoom eye piece. What do you think of those?
i agree with Joilly. Thank you for packing so much golden info into a concise lesson
I found a old Montgomery ward telescope in closet. Needs cleaned. And needs eye piece ordered one. Hoping it comes so I can clean it up and check it out
Great vídeo straight to the point. One question: do you think a 10 inch is worthwhile when compared to an 8 ? Mobility is not an issue. I am just wondering If the image improvement worth the extra money. Thanks Allan. All the best
My goodness!!! What a wonderful video!!! It answered all of my questions. Thank you so much!!!
Clarifying the questions about eye pieces. Thanks
Thank you Allan. Very straightfoward and helpful.
thank you for these educational videos, good mix of learning and recomendations.
Thank , thank you , I cannot thank you enough for clearing and answering my questions so freely.
You are very welcome! Be sure to subscribe so you get more great tips!
My main pieces are
42mm orion deep view 2 inch
26mm orion q70
9mm Celestron lx xcel
Thanks finally got the answers I needed with eyepieces
This was the video I needed to watch! Thank you! I have a question. Last night I found Jupiter using my 25mm and 10mm lens and it looked the same using both eye pieces. Am I doing something wrong? I thought the 10mm would bring Jupiter much closer to me? Just subbed to your channel and am going to binge watch and learn. Thank you!
The 10mm should make the image larger, but it will also make it a little less sharp. If both seem to show the same size image, then I would say something is wrong. See if there is a local astronomy club in your area and ask to borrow a couple of inexpensive eyepieces to test. You might have one that is mislabeled or just bad.
This 1 video answered all of my beginner questions. Thank your very much :-)
Great video , its helped me understand alot more , i do have one question, what is your view on lenses thats can be adjusted from 7mm-21mm are they any good or a waste of time ?
Nice break down Allan - much appreciated
Thank you for your advice. Very simple and easy to un
derstand for a beginner and daughter.
Great vid ! Can you suggest what are a couple of good starter eyepieces for my new Celestron 8 HD ? Thanks
Thanks for all the useful, helpful information on eyepieces!
thanks so much for the information...it was easy to understand and now I know what i need for my new scope.
Great video. Now, what about moving the eyepiece in and out of the socket, does that focus it?
Thanks for the video. You get to use more those 2 eyepieces but with what kind of telescope?
Thanks for the video, but do we need to know if these are Huygens, Plossl, Kellner, etc? BTW, the beginner scope I have has 0.965" diameter pieces and I wear glasses so will definitely be looking to upgrade.
Thanks for the down-to-earth explanation! :)
Very informative. Thank you for sharing your knowledge. I've had a reflector telescope for years and only used it twice to look at the moon. I'm hoping to get some good pictures of the Neowise Comet. Wish me luck.
Good luck!
Great video. Are eye pieces a standard size and interchangeable across telescopes?
Thank you very much. I found your lecture very clear.❤❤
Simply buy "baader hyperion 8-24 zoom". These are all in one eye piece. No hassle of changing eye pieces while observating celestial objects.
What an awesome video! You should provide links to the eyepieces you were displaying - Overall AWESOME VIDEO! TY!
Excellent catch, did not realize I had not done that. I put some links in there now. Appreciate it!
Useful information for me, thank you for making your video!
Thank you so much!
Man is this a world of stuff to look into :)
Thanks for this, very helpful for us newcomers.
I would appreciate an update on some of the barlows and lenses I currently have a c8 Celestron that I've built from trash I got it up to working condition I really would appreciate an update and links to where we can get the most cheapest barlows and lenses
Thank you for the video.. It helps me alot. This is what i exactly needed. Simple and clear explanation
Very good info, exactly what I was looking for. And you make it so easy to understand. Thank you
Great Video, definitely going to check out the Orion Stratus. I have a AWB 5" reflector made by Celestron.. 650mm focal length, came with two beginner eyepieces, 10mm & 25mm kellner. I really want that wider field of view, do you think a 68 degree eyepiece will do or should I look at say a Celestron Luminos which is 82 degrees. Thanks for the help!
I think how wide a field of view a person prefers is a very personal thing and there is no right answer to it. Each person also might view the optical quality differently as they are more bothered by one type of optical imperfection than another. That being said...
My opinion is that the Stratus eyepieces are better optically than the Luminos eyepieces and the ability to use them in both 2” and 1.25” applications is a really nice addition. Those qualities would outweigh the wider field of view of the Luminos for me.
I do enjoy my 82 degree Naglers but that is a combination of the wider field of view and the amazing optics in these things. There is something to be said for what appears to my eyes as optical perfection from one edge to another. That is something I had never had in an eyepiece before the Televues.
The real truth in this conversation is that no matter which you go with it will be such a huge improvement over those Kellner eyepieces you have now that it might not matter at all. Whatever way you go let me know what you did and what you think of your decision after the fact, love to get new opinions!
Hello Alan, Thanks for the information. I am definitely leaning toward the Orion Stratus eyepieces, the 68 degree field of view compared to what I am using now (probably 45 to 50) I am sure will be a huge improvement, I prefer a wide field of view. I will keep you posted on what I end up getting & what my viewing experiences are. Thx!
