Bubble Nebula (NGC7635)

The Bubble Nebula is a hydrogen-rich emission nebula in the constellation Cassiopeia. It is 11,000 light years from Earth. This photo also includes the open cluster M52 and NGC7538. This image is a composite of shots from two sessions.  The area immediately around the bubble is from my AP 142 at f/7.5 (1065mm focal length), while the rest of it was done with the AT111EDT at f/5.6 (622mm fl). The wide shot was the first image I captured with my Astro-Physics Mach1GTO mount. Captured on 2011-10-25 & 26 at Wa-chur-ed Observatory using H-alpha for red plus green and blue filters. […]


Lamb’s Head Nebula (NGC7822)

Although this region is part of a larger structure known as the “Question Mark Nebula” (this being part of the semi-circle in the question mark), this fascinating region itself does not have a common name. I’ve decided to call it the “Lamb’s Head Nebula” because of the obvious (to me, anyway) shape near the top center. Scope: AT111EDT at f/5.6 Mount: AP Mach1 Camera: QSI 583 at –15C
