TS 65 Quad Refractor Review (part 2)

[@coloradoastro6139]

Thanks for the video! This helped solve the issue on my Meade 70mm Quad!

[@astronomyshed]

Glad it helped

7 years later the same operation was needed in TS EDPH II. The lens ring was screwed extremely tight and loosening it got rid of the pinching.

[@RS3Tube]

Used this for my newly acquired (used) TS optics 80mm triplet last night when I noted misshapen stars. The retainer ring was on the back of the cell on my version (side closer to the focuser) and was extremely tight - once I’d loosened and tried today my stars were nice and round so thanks for this. Oddly enough the stars have some blue CA which I’ll need to look into.

[@RS3Tube]

Re: residual CA, I have checked my TS optics 0.79x flattener and the retaining ring is way too tight, tight enough that I can’t loosen it with the grooves 180degrees apart and a flat head screwdriver. Any thoughts as to how to loosen it? I’m only 15-20 minutes from Bolton if you have a practical solution in mind. Can pay in cash/beer!

[@licho52]

@@RS3Tube The flattener in my TS was also tight, I used a wooden golf tee at an angle until the ring finally gave. Took a lot of effort.

[@JohnMcGFrance]

Thanks for this. I have the TS65Q and noticed slightly strange stars on my last session when it was cold. I’ll check the tightness of the retaining rings. Great channel.

[@astronomyshed]

Thanks. Can almost guarantee that is what it will be. The T65 was my absolute fave scope. It's absolutely stunning used visually on the moon too.

[@danielbeetsma6118]

This was extremely helpful. Thank you very much for taking the time to upload this! Also, there are such retaining rings on my TS Flat 2 flattener, and I wouldnt be surprised if they are also present on the TS 0.79x 4 element reducer (which I currently use). The same trick applies then, of course.

Oh my friend!! Thank you very much!!. I hope fixed the problem with my TS Optics Imaging Star 70 mm quadruplet.🤗

[@jennyking4107]

After quite a few years of use my TS 71 q has developed pinched optics. I tried to loosen the retaining ring and bought a pin wrench but it won't budge. Hope you are well mate, love to you and yours Jen

[@astronomyshed]

Not bad Jen considering. Try a bit of WD40 but don't spray it on, spray some in the cap and then use something to put a drop or two on the threads and let it sit a while, also I'd try a hairdryer on it (the scope not the WD40) ;)

[@ohmyohmyohmy2]

Very informative. Thanks for posting. Never knew you could disassemble the entire refractor like that.

[@Scubapeks]

Thank you very much for this great tutorial ! I had a lot of trouble to loosen the retaining ring of the corrector element even using tools...Now I think my elongated stars pattern is fixed in my AT65EDQ.

[@astronomyshed]

It probably is, if it was actually that tight then it was definitely causing you a problem, please reply here if it is definitely fixed.

[@Scubapeks]

astronomyshed The optic is still not right. Still under warranty. I'll bring it back to the store. Maybe there's a little something that isn't properly aligned.

[@gapteckspace]

What do you think about Ts Optics The PhotoLine 60mm Fpl 53 + Skywatcher mini star Adventurer. It' s a good idea? Or no?

I think if you have the front element rattle like that then the collimation would be way off?

[@thepecha7]

Very informative Dion! If you have no plans for another video, it would be great to see an updated polar scope webcam mod. I have had no luck finding a SPC900NC and have no idea about webcams and what models would be successful at fitting to the scope!

[@genogeno1234]

Thank you for posting this!!! Solved my problem

[@astromanicdave]

I ordered the TS80 quad, just one question you may know the answer to, the focal length is 480mm of the triplet and when its turned into a quad this becomes 520mm, why is that

[@paulwalsh9680]

I've used a Logitech Quickcam E1000 for imaging before now. Haven't tried it as a guide camera though. Fortunately where the lens screws into has the same thread size as the SPC900NC so an adapter for the Philips will fit. The E1000 doesn't appear to be available any more, but there are similar looking cameras which might do the trick

[@86xxxxsnake]

hi! i saw this video just now... i have a Tecnosky 65q (but i think they are the same manufactory mode), i have a problem with the corrector, like it does not correct an Apsc sensor... i try to do the unlock e lock of the ring stop of the corrector but still the bug in the correction... Do you know wich is the right distance between the corrector and the last of the other lenses? thank you in advance for any reply!

[@astronomyshed]

Sorry, No Idea.

[@MrIsrael701]

Very useful video. Thank you very much for sharing your expertise. Regards.

[@clintkennedy8374]

Liked and subbed thanks for this!!

[@pawepiechnik6248]

Brilliant. I may try this for the 71SDQ ... nope, it's glued in this one

I got the 71sdq and the star is comma as well. Did you solve this problem with your scope?

Mine is not glued. I tried and could lossen the retaining ring in both the front element and the field flatenner. Did not have the sky to test it the last few days though. Hope it helps to correct the coma that I'm having with my 71sdq

[@pawepiechnik6248]

@ I think so. I took a long time but eventually it's acceptable now. have you ?

[@LiveDeerCamByCajun]

very helpful, thanks

[@kingdom777866]

Now I know why my wheel nuts were loose, I thought it was the bastad next door !!!!

[@GamjaField]

Wouldn't it throw off the collimation?

[@astronomyshed]

Wouldn't 'what' throw off the collimation?

[@GamjaField]

@@astronomyshed I mean the spacer adjustments around the 5 minutes mark.

[@astronomyshed]

@@GamjaField The lens elements in a refractor are not supposed to be tight, it has to allow for temperature changes whilst eliminating pinch.

But once the lens rattled in the case like that, wouldn't the optical axis of that lens no longer aligned with other lens in the telescope?

[@astronomyshed]

@ The movement is very minimal, you do know that even in a reflecting telescope, there is supposed to a be paper thickness space between the mirror clips and mirror?

[@papergames2505]

boo!!!!!!!!!!!!!!!!!!!
