SH2-200 (Captured 1/13/26)
SH2-200 (aka Bear Claw Nebula) is a faint planetary nebula in the constellation Cassiopeia. It was originally cataloged by Stewart Sharpless in 1959 as a H2 region, but later confirmed to be a planetary nebula in 2017.
The annotated image to the left shows other items of interest in the capture.
The image consists of 53 Sii, 63 HA, and 74 Oiii five minute exposures. The stars are 45 min of RGB made of 30 second exposures. These images are stacked together to increase the signal to noise ratio resulting in a total integration time of 16 hours and 45 minutes. I processed the images using PixInsight and Adobe Photoshop software. I used my Astro-Tech AT130-EDT telescope, with a focal length of 910mm, a ZWO 2600MM astronomy camera, Antlia RGB and Antlia 3nm Sii, Ha and Oiii filters . I used the Orion Short-Tube 80 guide scope and ZWO 220MM Mini guide camera all atop the iOptron CEM70AW telescope mount.
