Should be very close to the crescent moon tonight 400mm or 600mm is the way to go. Just watch the exposure times due to star trailing. The longer lenses will enhance the movement.
Thanks for that.
I'll be shooting tethered and / or chimping on the rear LCD...but remind me...what's that rule of thumb again for star trails and focal length v
One thing I've been meaning to try out, and was going to try out tonight with Andromeda regardless, was using stacking to do some deep-ish sky stuff without a tracking mount for the tripod. The idea is to go ahead and shoot up to 25,600 ISO if need be to get the non-trailed exposure, but shoot a whole hell of a lot of frames, align them in Photoshop, and use the average blend mode to get rid of the noise. And then track the object manually. So, yes, I'll be cropping a fair amount around the edges because I'm not going to be perfect at tracking, but that's okay. I might even make use of that, and leave the edges ragged for artistic effect....
