The Moon Visits Venus Again

Yeah, I know. It's been forever.

I stepped out on the back porch this evening and saw this combination of the Moon and Venus, and couldn't let it go past.
That's Mars in the lower right!

M27, The Dumbbell Nebula

Once in a while everything during an imaging session works right. No meridian flip, no guiding issues, no focus problems--everything was clicking along for this one. I've been using a camera cooler for the last couple of shots, and am pleased with the improvement. It's amazing how much easier processing is with clean data to begin with!

I almost never image at f/10, but this is through the C11 at 2800mm focal length, There's some movement between the subs--probably from mirror flop--but in the end the stars are still pretty round. This CI-700 seems to be a keeper!

M57, The Ring Nebula

I've had the C11 for a while now, but this is the first time I've used it try shooting a DSO. This is the famous Ring Nebula, M57, a planetary nebula in Lyra. You can just see a barred spiral galaxy IC1296 below and to the right.

NGC 7635, The Bubble Nebula


I really shouldn't use APOD to pick out targets to shoot--it makes me want to spend astrobucks on imaging equipment.

Saturn 2012.2


The forecast was for 4/5 seeing, but I don't think it was that good. Maybe 3/5, but no better than average.
