Hi everyone here:
My name is David Williams. I'm from Centreville, MI and have a desire
to do deep-sky astrophoto-graphy. Just awhile back (1.7 years ago) had
our first roll off roof obs. And my equipment is now: A Meade LX200GPS 10" F10
an 80mm APO AT scope piggyback. An ST-2000XCM CCD dual sensor. A T2i.
And just now a Nikon D800 (36 megapixels). so that's cool. But on my setup
I've still been having the basic problems; of making my stars not so trailed.
And focus I'm just eyeballing. And there can still be noise issues, because
at sake of trying to not allow my image to trail I'll boost up the ISO so then
the noise comes out. Guess the right thing is a balance?
But I've tried doing PhD guiding and that was a learning experience.
Though at best (after tweaking more the wedge right) the graph looked a
little better, with the lines going not so vertical and could go for maybe
10-30 min before the ding would happen and get out of the green box.
So last year my accomplishments were the best at M51, then for the first
time the nebulosity around the Pleiades, then for the first time the Horse-
Head nebula. So I suppose something was being doing right.
But now I'm looking to do adaptive optics: Any advice here?
Like I'd like to use my new Nikon D800 DSLR to take the image (it's got a
35mm size sensor at 36 megapixels) And was either considering the
SBIG AO line or the Orion Steady ones.
Does anyone have also advice of what that would cost? And what
final equipment I'd need? Thank you.
David
