Thanks for the help

Have a look at this video:

https://www.youtube.com/watch?v=Ylb7xnc_03U

It shows whole process of disassembling ST80 refractor telescope and blackening lens edges to improve contrast. Interesting parts are re seating the lens back in lens cell - tapping to get it to seat properly. This part is at around minute 5-6.

Like Ed pointed out above - you can just slightly loosen retaining ring - and then tighten it as instructed in video - each time gently tapping / shaking scope to seat lens properly - and just slightly touch up on retaining ring without forcing it.

Thank you!

Using the Celestron AstroMaster 102AZ achro. They have all been taken with a Samsung Galaxy S10 Plus, handheld over various eyepieces. Most have been edited to enhance contrast, sharpness, some have been stacked. Hope you like em'!

Hi @Buqibu 

What scope do you have? 

Its an AstroMaster 102 refractor, 660mm fl

Thanks!

It does kind of look like that, if it is pinched optics, can it be fixed?

What do your views look like? Maybe one of these images:

These show "progressive" improvement in seeing conditions. Only good and very good seeing will show definitive disk with either broken or full rings around it.

If your view resembles - first three images, then I'm afraid, it is the seeing. Check out some of the guides for optimizing planetary views (cool down, choice of location, time of the night, target near zenith, etc ...) - same things apply here

I see the first three, but not that bad, its more like a triangle looking shape. Could it be the optics? It really only bothers me because of some close double stars, doesnt't seem to affect other observation. 

Hello, I've read that stars through a telescope show up as small discs with diffraction rings around them. I have a 4 inch achromatic refractor and have never been able to see this. Could it be the optics are sub-par, or has the seeing never been good enough? The second seems unlikely, as I've tried it on multiple occasions, through high magnifications, but always just saw a deformed smudge, not a defined disc. Thanks for any advice! 

Celestron AstroMaster 102AZ, using Celestron Zoom eyepiece around 15mm. Took super slow motion video with Samsung Galaxy S10 Plus handheld. Proccessed in pipp, took 1200 frames, stacked about 15% of them (i think) in registax, edited wavelets, and then played around with brightness and contrast in windows photo editor and snapseed.

Oddly enough the way scopes work means that a 100 inch Dob would get no more light into your eyeball than a 2 inch refractor and certainly less in both cases than no scope at all. What does change is the scale of the image you view.

Really? Huh, thats odd to think about, guess it makes sense, they don't really make stuff brighter, just allow more magnification at a given brightness

I know aperture aperture aperture is better for the pure visual experience, but when you can't bring yourself to use it, is it really worth it? Something small you can just throw in a bag, go hiking with, or simply bring from a room to your balcony and back easily, something that doesnt require time to cool down is very nice indeed. No hate for the light buckets though, they give us the "wow" factor, small scopes bring the "aww" factor

Thanks, that makes sense!

I was at a public viewing site and looked through a reflector. Can't say the exact model, but when I looked at Venus through it there was this crazy rainbow blue and red fringing around it. Thought it looked very odd, even more so than in my achromatic refractor. Any ideas why this could be? It was relatively low near the horizon, could've also been slightly out of focus, but still surprised me

Thank you!

Edit, sorry for the weird white background text, copy paste is to blame🤣🤣

This month marks the first year of my amateur astronomy, here are the 50 or so objects I've seen! Note: all observations were done with a 4 inch achro, a pair of 10x25 and then later 7x50 binoculars, and a few with the eye alone. Bortle around 6

The List:

The Moon
Jupiter (and it's four Galillean Moons)
Saturn (and Titan)
Mars
Venus
Achird (double star)
Mesarthim (double star)
Almach (double star)
Andromeda Galaxy (M31)
M32 (i think)
M15 (Globular Cluster)
The Double Cluster
The Owl Cluster
Pleiades (7 Sisters)
ISS
Perseid Meteor Shower
M103 (Open Cluster)
NGC 663
NGC 559
Neptune? (maybe, I though I saw a blue star)
Uranus? (Same situation)
Mizar and Alcor
M52 (Open Cluster)
M34 (Open Cluster)
The Hyades Cluster
The Orion Nebula (M42)
M36 - open cluster

The Coathanger Cluster
Alfirk - double star
M2 - Globular Cluster
NGC 752 - open cluster

Been into astro for about 1 year. I have a 102mm achro and a pair of 7x50 binoculars. I find this stuff fascinating and can't wait to learn more🙂
