Hi all!
Longtime lurker on here, only really done some really basic sky imaging, mostly really widefield stuff, as well as some unguided with my Canon 100-400mm lens, which is not exactly ideal (see attached M42 & Saturn images). Anyway, finally getting round to actually getting myself a proper scope, I'm looking at a second hand Dobsonian to start off with (a 10" Skywatcher to be precise), just wanted to know if anyone has any tips as to what sort of things I should look for to make sure all is good with it?
I'll be looking at bolting my Canon SLRs onto it for some imaging as well (mostly planetary given it's not a GOTO), as far as I can tell I'll be needing a T mount and ring to get that setup, I've only seen Celestron branded mounts on my limited searching, will they still sit okay on a SkyWatcher?
Also looking for a 2x Barlow, is there much difference in sharpness/light loss between difference types/brands of Barlow or are they all much of a muchness?
Hope that made at least some sense, look forward to getting some viewing done!
Cheers,
Marcus
