NGC 7331, known commonly as the Deer Lick Group, and Stephan's Quintet galaxy groups in the constellation Pegasus.
This LRGB composite mosaic consists of 320 frames totaling 65 hours of exposure time. Individual exposures include 70 - 900 second luminance frames centered on NCG 7331, 70 - 900 second luminance frames centered on Stephan's Quintet, 60 - 600 second red filtered frames, 60 - 600 second green filtered frames and 60 - 600 second blue filtered frames. Luminance frames were captured using a Takahashi TOA-130 refractor, QSI583wsg CCD camera, Astrodon GenII filter and Astro-Physics AP900 German equatorial mount. Red, green and blue frames were captured using a Takahashi FSQ-106 refractor, QSI583wsg CCD camera, Astrodon GenII filters and Astro-Physics Mach1 German equatorial mount. Image calibration and processing was accomplished using PixInsight.
