I have never had any concrete information from any of the Forums. I have exactly the same type of Telescope as you and frankly trying to get information which is correct is like a Dentist extracting a tooth!
Always wonder if I am talking to shop owners who want us people to end up with a pile of crap lenses until we end up with what actually works. Just saying!
I am using the Plossl fully multi coated Lenses which are to me ok to look at the moon but chasing quality detail on the planets forget it!
Try getting crisp details in Deeper space for Nubulas etc forget that also. I have a lot of gear but useless without the right lenses as you and I have already experienced.
I have even gone to a Forum which had a Celestron Site but the info from there was useless as it was conflicting too much with peoples ideas.
If there are conflicting ideas from people who are looking for the same thing ie deep space or planet viewing then you would think there ideas are the same! The reason I say this is Celstron make a pretty good scope which must have quality control in place , so therefore there should be very little difference between your scope and mine regardless where you live on this planet if in the same temperate zone north or south of the Equator. Do I need correcting?
I have read my Celestron manual through from cover to cover and I have bought the Camera Extenders but still crap.
Celestron are so behind in their manual for the CPC 800 they are talking about only cameras that use film not digital.
Well that's in my manual anyway. I don't think it matters though.
So you can image you may have to join a local Astronomy Club and hopefully someone is operating the same Scope as yours and you can see what he is using and just copy.
With this hobby when you start off and have not joined an Astronomy Club I think us people are leaving ourselves open to Sharks quite frankly!
Best of luck with your endeavours!
