Description

Wide Field image in Cepheus including the popular Cave Nebula (Sh2-155), Lobster Nebula (NGC 6357), and Bubble Nebula (Sharpless 162, NGC 7638). This is SHO using my Canon ES135mm lens, ASI1600MM-COOL and Astrodon 5nm Ha, OIII and SII filters.

This is part of the Milky Way with many DSO targets. The major ones are the Cave Nebula (Sh2-155), Lobster Nebula (NGC63567), and Bubble Nebula (Sharpless 162, NGC7538). There are many other smaller Sharpless catalog targets (i.e., Sh2-144, Sh2-146, Sh2-147, Sh2-148, Sh2-149, Sh2-152, Sh2-153, Sh2-154, Sh2-156, Sh2-157, Sh2-158, Sh2-159, Sh2-161, Sh2-162, Sh2-163); Planetary Nebula (PK107+02.1, PK107-00.1, PK108+00.1, PK110+01.1, PK110-00.1, PK110-01.1, PK111-02.1, PK112-00.1, NGC7354) and open clusters (M52, NGC7419, NGC7429, NGC7510) and emission nebula (NGC 7538).
