Hello,
I'm new in AP, I have no scope yet. I think I'm going to buy a c8-sgt. I wanted to know what you guys think about that choice; my main goal is to watch the moon and planets such as jupiter and saturn. But I'd like to take some pictures of the moon and also jupiter and saturn, mars. I know f10 is not good for taking pictures of deep sky objects, but is it a good choice for planets and moon? I don't want to buy a guide scope or focal reducer, just the necessary stuff to use my Nikon D7100.
For eyepieces, I think about a 35mm for widefield and a 7mm (or less?) for the planets, I don't want to buy a kit. And a barlow 5x, is it too much?
That would be about it. What do you think? I appreciate it, thanks.
I think it will be a great package. You should be able to see and image (webcam style) some amazing solar system images. You should spend some more money and get a good webcam. DMK's seem popular and a mono with filters will produce some great images. I have a 2.5 X Teleview which is good but I have heard that for the 5 X you really need to have very good conditions to get the most out of them. May be good for viewing but have not done so. Enjoy it as it looks great.
I endorse what batema says, and would add that a 5x barlow is way too
much for your scope; it would provide powers that the atmosphere would
rarely allow you to use with your long focal length scope. A 2 or 2.5x is
a much better option.

Thanks guys. I'll think about it for a web cam, I'd like to stay below 2000$ for the whole thing. Maybe I'll get lucky for a deal on boxing day! I'll add a 2.5X, still I might get a 5X to see for myself
Thanks again!
I have 3x on my 9.25 SCT and very rarely get to use it due to conditions and the strength of the F10. Especially when attempting to take images of the planets. Unless you are willing to spend the money on a TeleVue Powermate and only use it a handful of times a year its money better spent on your AP side of your new setup. The best bang for your buck if you are keen on a good unit would be the 2.5x Powermate not only will it magnify the image for visual it will be much crisper than a Barlow for imaging. When using a CCD imager with an F10 and a Barlow, the more magnification you get the more light you loose and the more clarity you also lose. Looking at the budget you have you will probably starting out with 1/3" at max CCD chip and using a 5x with this will be extremely hard. But saying all of this you will get some cracking visuals on the times you can use it.
Hope this helps a bit the C8 is a nice tube and will work well for the planets and if you add a 6.3 reducer and use a DSLR you can certainly achieve some great deep space images aslo.
Thanks I will go for a 2.5x powermate since it makes more sens.
I have another question, should I consider any filters? For light pollution?
I know almost nothing about them.
So I got my new scope today, a c8 with a AVX mount
The seller at my local store said I would waste my time trying to take good pictures of the moon using my nikon 7100 and a powermate 2.5x... I don't know. I didn't buy any barlow or t-ring for the moment.
Congratulations Illastro. I would set it up and look through it manually at a couple of obvious things such as M 42, M 41 Jupiter. Your camera should be fine to prime focus so I would go out and get a Nikon T ring and a 2 inch tube and bung it on the scope and see what you get. Remember it is a long learning curve but well worth it. I am going out to a mates place tonight to image and I can not wait. Well done and be excited.
