As some of you may have figured out, I’m new to all of this astronomy stuff. I
just about have everything ready for this weekend’s AASP and I’ve started
dreaming about what objects I’m going to try to image. But in order to make a
sensible target list, I need to make a reasonable estimate of how much exposure
time I should give each target. And I have no idea or feel for where to even
guess! I’m hoping one of the more experienced imagers could give me a hint as
to where I should start.
Everything currently on my tentative list is between 6 and 8 magnitude
(according to Stellarium). My scope is f10 plus a f6.3 reducer. I have a mono
ZWO camera so everything will be LRGB or maybe some Ha thrown in if I get brave.
Orion or Horsehead Nebula if I’m up that late--
