Three galaxies in Draco
Abell 1377 Galaxy Cluster and neighborhood
11 images in luminance showing the galaxy cluster Abell 1377, each with 180 seconds of exposure, captured using a 0.61m f/6.5 Corrected Dall-Kirkham Astrograph at the Sierra Remote Observatory. Calibration, registration, and stacking were performed with IRIS. Before removing the background gradient, a star mask was applied to reduce the star brightness, allowing the galaxy behind to become more visible.
NGC1097 (Caldwell 67)
NGC 7640 in Andromeda
Barred spiral galaxy located in the constellation Andromeda, distant about 40 million light years from Earth.
NGC6946 in Chepeus with a 0.61m Astrograph
The final result is the combination of 4 images at 120 seconds in Luminance for a total of 8 minutes exposition with a Planewave CDK 24” in Sierra Remote Observatory at Auberry California.
