Hi I am fairly new with telescopes and I noticed my telescope needed collimation. I preview the collimation at the beginning (tell me please if its alright) however after I finished the secondary mirror kept tilting and not staying in place as seen in the video. This is a Heritage 130P telescope. Please help.
I want to purchase the AC for optical axis calibration, but after consulting the jim fly, he is not sure whether the tool can be operated on the hyperboloid primary mirror, so has anyone used the catseye autocoliimation tool to perform the optical axis on the sharpstar 150hnt f2.8 Calibration, please share information, thank you
Just thought I'd share this in case you haven't seen it already. A recent (September 2020) article added to the Celestron 'Knowledge Base' on collimating SCTs.
I don't claim to have seen all articles on collimation, but this is defs one of the best that I have seen.

I really want to get out and do some observing- it's been a long summer!
Does anyone know of anywhere near Glasgow that you can get to by public transport that's ok for observing.
I'm not looking for super dark skies- I just want to do something.
I don't drive so mugdock, campsies etc are out of the question. Kelvingrove has been ruined by that glasglow event every winter.
Thanks for any help!
