Beginner Telescopes: The Refractor
HTML-код
- Опубликовано: 18 дек 2024
- In this short video I give an overview of the refractor type telescope and why I think it would make an ideal starter telescope for anyone just getting into astronomy or astrophotography.
Here is a link to the cheapest telescope I could find which is similar in power to the one I feature in the video, albeit this one comes on a rather wobbly tripod www.amazon.co....
The link below is to a more upmarket telescope on a much sturdier tripod mount with alt-az control

Got it right this time folks! I only uploaded the outro last time lol
Something I’ve been interested in Stephen a very nice guide to star gazing M8
That was great thank you.If you demonstrate what you can see with each telescope it would be an interesting addition thanks.
I’m just getting into all this stuff! I like how you break things down. Your video is very helpful!
Glad it was helpful!
I enjoy your presentation about this little refractor! Thank you :)
My pleasure!
Very interesting, as always! I wondered how you would overcome "fogginess" - answered👍
Very interesting video on how to use the telescope.
Very interesting 👍
Stephen, your videos are always interesting and informative. I always watch you on starman and a walk on the wild side. Please keep up the good work.xxxx
Very true! Thanks for this
Great info video, you have answered so many questions in one go, thank you 🙏
Great stuff.
nice doublet APO ed glass very professional scope travel model
Very clearly explained. Thank you, Sir :)
Would be nice to see a video with the subject APO vs achromat at the same aperture or the same price for visual observations (not astrophotography) :). For the same price you can get an almost 2x bigger aperture achromat. And I also wonder how different the image quality is between an APO and achromat at the same aperture. At the same aperture the acromat is 2-3x cheaper.
I'm hoping to do more reviews next year, so hopefully I can do that. I am looking to purchase a new refractor very soon, as this one was on loan.
Dude you're great keep it up ! Could you please at any time make a short vide of how to position my refractor scope on stars (firmly) so I don't lose them 10 sec later when I wanna change the eyepiece , maybe Im missing something and Id love a quick crash course
Ok it sounds like your mount may be a bit wobbly. A decent mount should not move off a star if you change an eyepiece.
@@starman1969 brother thanks for the reply ! you are right ! I do have a hard time keeping it in place , is that because of the cheapness and crappiness of the mount or I have made it too tight or ...
@@geraltapprentice6394 I'd guess it is the mount. In astronomy, whether visual or for photography, it is important to have a solid mount that can more than handle whatever telescope you put on it. German equatorial mounts are the most popular. Have a look at something like an EQ5 and see if something like that would be practical. I'll try to do some videos on mounts very soon.
really well done.,apart from the ending, a really great effort.[..if i do say so myself!]
Does the Nat Geo CF600MM 50MM telescope have a solar "cover" to view the April 8th eclipse?
I don't know, but it would be easy enough to make a solar filter for it.
Hi Stephen I'm currently using my Nikon D500 and 200-500mm lens on the Skywatcher Star Adventurer Pro tracker but looking at getting a telescope later this year. I'm leaning towards either the William Optics Zenithstar 61ii or the Skywatcher 72ED from what I've read / seen on RUclips the WOZ61 has better build quality (I also love the different colours 😁) Do you have any advice pros/cons with either scope?
Between the two I would definitely say the WO 61 ii is better, even though they don't quite match up for focal length. At least the WO 61 has the same aperture speed, at the expense of slightly less focal length. There is another deal breaker for me, which would make me choose the WO and that is that it has a Rack & Pinion focuser, whereas the Skywatcher has a Crayford type focuser, which I don't rate as highly as R&P due to them slipping when putting on a heavy camera. R&P focusers do not slip.
Are you doing a livestream tonight Stephen?
Yes I’ll be on tonight. It’s a Mars special!
What would you recommend for a star tracker for this setup? Thank for sharing!
I have a Fornax LighTrack II
Can i replace the 20mm to 5mm ?
thx
Single lens are not achromat, they a chromats lol. Doublet crown and flint is achromat, doublet Ed is semi apo or apo depending on type of ED glass and focal length.
Most triplet Ed and flourite are apo, but in the early days some triplets were semi apo.
Flourite doublet and triplets are generally all apos.
It irks me when I see people on youtube call singlets achromats. There is no such thing as a singlet that can correct for any level of chromatic abberations, even basic achromat level of correction which leaves only the purple fringe. Singlets were like prisms with a rainbow of abberations
You sound a bit like one of our ex astro society members who was always correcting us about certain terms. He was always right, in his eyes, but none of us particularly liked him.
@starman1969 welcome to the world of aspergers. You will find a bunch in the astro community and yes, they are usually right. And it is a pity that people would rather be wrong and dislike those that are right, but have a direct way of letting you know, rather than just sugar coating everything or sacrificing their principles for the sake of being well liked.
recommending an £800 telescope as a beginner scope lol!
I know lol. There is a link to cheaper scopes in the description.
He's reccomending a class of scope - not necessarily THAT exact scope.
The class being a moderate apature, moderately short tube refractor. (80-100mm with f5-f8 focal ratio)
Try the explore scientific 80x640mm firstlight scope on the twilight altaz mount.
Great inexpensive beginner setup. Add a couple eyepieces to supplement the 25mm plossl it comes with... maybe a 2x barlow and some filters?
That'll get you started. and later will serve as your grab n' go rig or maybe a pass on scope to another noob or some neighbor kid once you decide to upgrade.
You don't need to spend thousands to get started... and your first scope can continue to serve a purpose even if you DO catch the bug and spend thousands later...
Provided you bought a quality inexpensive instrument.
