    Thanks for making these videos. As a beginning astronomer, who is learning, it's nice that you seem to not be reading cue cards, verbatim. Although organization and clear content is paramount to an easy-to-watch tutorial, I can tell be your tone that you really live this stuff. Thank you, again.

    Hi Geoffrey,
    My first suggestion would be to get a 2x Shorty Barlow lens. It will double the power of the 25mm, and work with any eyepiece you get in the future. It's a great way to expand the power of your telescope.
    Thanks

      Bob Ross but 5 barlows (I’m assuming 2x) would magnify anything by another 10x so still very high magnification

    great video....but I just want to make a note on eye relief for eyeglass wearers....yes, it's true, with very short eye relief, eyeglass wearers can never get their eyeball to the eye relief, however this is slightly disingenuous, or not entirely accurate anyway. If an eyeglass wearer removes their glasses, and slightly defocuses the eyepiece, most people can offset their eye focus issue so that the image is sharp. It just wouldn't be sharp for a non eyeglass wearer at that point. This is similar to the diopter on a camera viewfinder. With my glasses on, I set my diopter to a sharp image. If I remove my glasses, the viewfinder is out of focus, but I can refocus my diopter for my vision without my glasses, and the image is again sharp. If I now put my glasses back on, and don't readjust the diopter, the image is again out of focus, so it needs to be refocused for my glasses. The same holds true with telescope eyepieces, for MOST eyeglass wearers. This does of course depend somewhat on the reason for the eyeglasses. Just wanted to make that clarification.

    • @jamesmcpherson1590
      @jamesmcpherson1590 5 лет назад +5

      True, but I wouldn't call it disingenuous. Probably just a minor oversight; easily made by a person who doesn't wear glasses. I wear glasses and I find it a pain in the ass to take them off for telescope viewing. This leads me to favor long eye relief eyepieces so that I don't have to.

    While reading articles and checking on forums is helpful, there is something that makes a video easier to understand, if done right. I have yet to come across a video on Orion's page that is anything but informative and easy to follow. In the near future, I will be upgrading from my first pair of binos to a telescope; I am leaning towards the XT8 Plus. Thank you to Orion for producing these wonderful videos, and clear skies to all!

  • @oriontelescopes
    @oriontelescopes  11 лет назад +5

    Hi Egov,
    If you have the Classic with only one eyepiece, I'd recommend something around a 10mm, and maybe a barlow to add with it. This way you'll have a wide range of power. The 10mm Sirius Plossl is a good eyepiece, similar to the 25mm that came with the telescope. Or the Expanse 9mm would be a wider field alternative.
    Thanks

    Hi arsa525,
    A moon filter will cut down some of the light, so if your scope is sending a lot of light to your eye, it can definitely make things more comfortable. Think of it like going outside on a sunny day without sunglasses. The filter helps knock down the glare.

    Hi Galileo,
    The E-series eyepieces are an entry level series, and don't have the same level of coatings as the Explorer II -- so the brightness will be better on the Explorers. Also, if you're using a higher power eyepiece of any type, it will appear dimmer and perhaps not as sharp if the atmospheric conditions aren't perfect. If you like the Explorers, I would suggest a barlow lens to use with them, or a Sirius or Highlight Plossl.
    Thanks!

  • @oriontelescopes
    @oriontelescopes  11 лет назад

    Hi Hisham,
    I'm trying to figure out exactly what you are describing, and I think I might understand. When you say your eyepieces are 0.79 and 0.16 inch, I believe you are talking about the focal length. Usually that's expressed in mm, so they would be a 4mm and a 20mm. The 1.25" refers to the diameter of the barrel and not the focal length, so just measure the barrel of your eyepieces (where they fit into the focuser). If it's 1.25" then that kit will work.
    Thanks!

  • @oriontelescopes
    @oriontelescopes  12 лет назад

    Hi Grannyhauenstein,
    The Sirius plossl is a regular Plossl design - "Sirius" simply refers to the model name. We have the Highlight Plossls as well with a few added features, but they are also a standard 4-element Plossl design.

    Hi Dosagu,
    It just has to do with the length of the tube. A long Barlow can be 5" or 6" long, and a shorty style can be around 3". They're nice to have in a refractor or cassegrain diagonal, so the eyepiece doesn't stick very high out of the diagonal.

    Hi Ptrssniper1,
    The 5mm and 6mm should work fine with the SpaceProbe130EQ. But the 3.3mm will probably push the power a little too far and end up showing you less detail instead of more.

    Thanks!

    Hi Ric300078,
    I don't think there would be anything wrong with a 10mm with a wider field of view. Yes, the Mak has a bit of a narrower light cone than a faster scope, but there's still plenty of room for going wider without loosing brightness on the edges. I think you can go up to at least a 66-68 degree field eyepiece without any problems.
    Maybe look at the Expanse or Stratus line of eyepieces for a nice upgrade.
    Thanks!

    Hi Duvan Jaft,
    I had to use Google translation so I apologize if I don't answer your question exactly. If you are looking for 3 different magnifications, I would suggest a 20mm-25mm low power eyepiece, a 6mm high power eyepiece, and a 2x Barlow lens. This will give you 4 different magnifications, and will let you see all the objects you mention. Try our Expanse 20mm and 6mm, and the 2x Shorty Barlow.
    Thanks!

    • @oriontelescopes
      @oriontelescopes  7 лет назад

      Hi Julio,
      I'd say a fairly long focal length eyepieces would be best. Since your 10" is already a huge focal length, it will be easy to over-magnify during the day and just end up seeing heatwaves and other distortion. So perhaps a Plossl in the 25-32mm range, or if you have your scope outfitted with a 2" diagonal, you can use a Q70 32mm or 38mm for even lower power wider field of view.
      Thanks

    This video was very helpful, for once I understood some math. Very well speaking for the viewer.
    I have a question:
    I have a 60*700mm refractor and a Bushmaster Mars 900 Reflector (Astronomical Telescope) .
    having my 10mm plossl divided by the focal length of the telescope, (refractor) that would give me 70* magnification right?
    and If I had a 6.5mm plossl plus the 700mm focal length of my telescope, that would be 107* magnification?
    Around what magnification is best for a mars 900 reflector (114mm aperture 900mm focal length) and a 60*700mm refractor for viewing details on planets such as Jupiter and close up observations of the moon (crater viewing?)

    • @oriontelescopes
      @oriontelescopes  8 лет назад

      Hi Galloping Gertie,
      Yes, you are correct with the formulas you quoted. For planetary details, as well as small details on the lunar surface, 100x is usually a good starting point for the best view. The 60mm will top out around 120x, and the 4.5 should hold up to about 230x, using the rather generalized formula of the upper magnification limit being about 2x per mm aperture
      Thanks

      I have one more question.
      I have a 2* Barlow with my 10mm eyepiece on my 700mm refractor. (the Barlow came with the refractor) with What magnification does that come to? I ask because when I view through this scope, I am not able to see details at all. Jupiter appears as just a small (reasonably sized) ball.
      Thank you.

    • @oriontelescopes
      @oriontelescopes  8 лет назад +1

      That would be 70 power times 2, so a total of 140x. That should give you the best image of Jupiter, so if it just looks like a small dot, I suspect you're looking at a star nearby. Make sure Jupiter is perfectly centered with a lower power view, then drop the barlow in.
      Thanks

      Through the Telescope! the max magnification you can ideally use for planetary observations is around 35x per inch of apperture. so for your refractor that would be around 84x. and you are using it at 140x , so i dont think you would be able to view great details 🤔 . P.S- i myself have 70 mm and using it at 90x doesnt produce that good views

    Hello Ken, I own a 4.5" aperture Orion Starblast Reflector Telescope with a 450mm Focal Length and am having trouble selecting eyepieces. Although I have been fascinated with astronomy for years, I only recently began skygazing with a telescope instead of the naked eye. Anyways, it would help tremendously to know what eyepiece to use to view two things: Every planet in the Solar System clearly, and the Andromeda galaxy. I currently own a 15mm, 6mm and Shorty Barlow lens and I am guessing that for planets, I need a better magnification and for Andromeda, I will need a wider field of view. Overall, the specific lenses I will need to be able to perform these tasks would be great to know. Thanks for the help.

    • @oriontelescopes
      @oriontelescopes  8 лет назад +1

      +LegendThePowerful
      Hi Legend,
      For planets, you're pretty well set with that 6mm coupled with the Barlow as that gives you 150x. You could push it a little more, and get around 200x-225x, so that would be a 4mm or 5mm eyepiece. Check out our Edge-On Planetary 5mm eyepiece (#8885) for high magnification.
      As for low power, go for as low power as you can, which would be around a 32mm Plossl. This will brighten up the view, and give you a wider field. Check out the Sirius Plossl 32mm (#8728).
      Thanks!

Do I have enough scope for that and just am still going through learning curve.. (Clusters are becoming beautifully easy) but do I need to step up the scope for galaxies and nebulae..?? If no any more advice? And if so where would you go next if u were me?? ORION ROCKS!!!

      Hi Rocco,
      Yes, you've got quite a good setup for clusters and nebulae. Some smaller globular clusters would do well with a medium power eyepiece, somewhere in the 13-17mm range if you don't already have something there. But for large faint objects, the 2" eyepieces you have are great.
      To get even more light and field of view, you could go with the 38mm Q70, but if you want even more faint object performance past that, then you'll have to start looking at an even bigger scope. But the 8" with a 38mm Q-70 will give you a fantastic image of many of the Messier objects.
      Thanks

      +oriontelescopes so I found its more of a local of experience than lack of scope.. I was somewhat on budget considering this was my first "real scope" last night I found Andromeda Galaxy.. Wow spectacular !! Now for some . They would say okay it's a grayish flattish round cloud.. But knowing what it is and what I found .. Was an awesome experience.. I like a go to system but I also like to "go fishing" but I just have to better educate what I'm looking at. I find the smart phone shows stars that under my light condition I can't even see so your basic constellations kinda get blended in with an index of every star. Even when adjusting the star visibility it's never 75 percent easier .. But that's what I love .. The challenge is fantastic .. I thank Orion Telescopes for helping me out so much ... How about we petition for something on Mars to have Kens name on it !!

      Interestingly,
      Only the bright galactic center of the Andromeda is what most people can see within the glow of city lights.
      The apparent diameter of the entire galaxy is about 3 degrees, or 6 suns/moons.

    hi ken , i have a 70 mm telescope with 900 mm focal length. i already have 10x and 20x eyepieces . which eyepieces do you think i should buy next ? (or if there is no need you suggest against buying one )

    • @oriontelescopes
      @oriontelescopes  7 лет назад

      Hi RB,
      If your eyepieces are 20mm and 10mm, then next step is probably around a 6mm. You can get a #8739 Sirius 6.3mm Plossl, or for a larger window and a bit more comfortable view, try the #8920 6mm Expanse eyepiece. Either of these will magnify more giving you a closer look at the moon and planets.
      Thanks!

    I have an Orion 4.5 inch equatorial reflector telescope with a 10 and 25 mm plossl eyepieces, which I use with my Barlow x2 and moon filter. What other eye pieces can I get to further maximize my viewing with this scope? I have seen people view planets and nebulas with a lot more detail with the scope than I am able to right now.

  • @JohnJ512

    Is that u means, Bigger magnification Eyepieces 66deg/40x=1.65deg FOV. Also plus
    your Exit pupil will also drop down from 80mm Lense size/40x = 2mm Exit pupil left.
    Is that correct? 2mm Exit pupil + 1.65deg FOV left? "How to see it in that way?"
    Is there any Exit Pupil Amplification in the Orion Telescope or Binoculars market?

  • @oriontelescopes
    @oriontelescopes  11 лет назад

    Hi Helena,
    Eyepieces are measured in mm, so if you have a 25mm and your telescope is 1000mm focal length, then the power is 1000/25 = 40x. A 25mm eyepiece will only give you the one power, so if you want more or less magnification, simply put in an eyepiece of a different focal length, or get a zoom eyepiece that can vary the mm focal length.
    Thanks

    Hey Ken, I have an Orion SkyQuest XT8, and I'm looking for an eyepiece that allows me to see better and father into deep space, I'm really interested in seeing nebulas and galaxies, I will do any price range, which eyepiece would you recommend?

    • @oriontelescopes
      @oriontelescopes  8 лет назад +1

      Hi Tevin,
      I would look at one of the Q70 2" eyepieces. They have a very wide field of view, and with a low power you also get a very bright image. The 38mm Q70 (#8829) would give you the brightest image of all of them, and would be excellent for many of those nebulae and galaxies that an 8" can see from a relatively dark sky site away from light pollution.
      Thanks

    @davidbrandenburg8029 4 года назад

    what can cause a faceting around the edge of the eyepiece lens when you look into it, it looks like those cheap diamond chip rings that used a diamond chip with extra metal faceting around the stone to make it look bigger. but when you look at it before placing eye to it and you see a starry ring with a hole in the center, and you have to focus on the small hole if you want to see anything. is this caused by out of collimation of the refractor?.

    Hello, I am a beginner and I was wondering if an Orion Starblast 4.5 EQ Reflector can use a 2 in barrel? Also, would a 3.5 mm or 5mm Stratus wide-field eyepiece work on my telescope? I would like to see the planets as close as possible without getting blurry, but I do understand that I have a beginner telescope. What is the highest magnification my telescope can handle? I did receive a 6mm and a 15mm Expanse eyepiece with my telescope. Would a 2x Barlow work just as good? If not, what would you recommend? Thank you!

    • @oriontelescopes
      @oriontelescopes  8 лет назад

      Hi Aliciasaurus,
      The Starblast 4.5" has a 1.25" focuser, so native 2" eyepieces will not work. But the 3.5 or 5mm Stratus would work because they have a 1.25" barrel. Either eyepiece would work, because with the 3.5mm, you are at 128x, which is well within the range of this scopes power limit. I would probably top it out around 180x-200x as a practical limit.
      A barlow is a great thing to have since it doubles all the eyepieces you have, so with your current set, you'll have up to 150x. If you get the barlow first, I think the next step would be the 5mm Stratus, as the 3.5mm would work ok by itself, but with the barlow would be pushing the power a bit too much.
      Thanks
