My goal with this photo was to capture Jupiter while it was near the Rho Ophiuchi Nebula and neighbors. I was excited to also capture Callisto at 2:00 next to Jupiter, I think M4 is pretty good, considering the focal length, and, given the short exposure, I was glad to get some of the Blue Horsehead. I was also glad that M80 turned out to be a star cluster and not something I screwed up in processing.
This was my first real effort with a guided SLR lens shot, (as opposed to a telescope). I was hopeful that the “vintage” Pentax lens I bought for $30 would deliver, and I really feel it did! This image is uncropped, and although it has some distortion in the corners, I think it is pretty acceptable.
This image was shot at Doney Mountain Picnic Area near Wupatki National Monument. The bottom right corner was showing light pollution from Flagstaff. It took a lot of work in processing to get that part of the sky relatively neutral, but I learned a few new tricks. It’s still not perfect. I did learn that widefield AP is far more susceptible to light pollution gradients, which is obvious I guess, but I hadn’t dealt with this yet.
SMC Pentax-A 50mm F/1.4 at F/4 and Pentax K3 II
Shot on the night of Friday, June 7th at Doney Mountain Picnic Area, near Wupatki National Monument, north of Flagstaff, AZ.
60 darks, a bunch of bias, no flats. (The flats seemed to be causing some sort of reversed vignetting? Either way, the image was improved I think without the flats.)
