The images have been processed with IRIS, alignment and stack of three images of luminance and three images for every channel RGB. No calibrations images have been applied. Total exposure of 180 seconds.
All the rights go to ASTRA Remote Telescopes and Susy Ghia for taking this beautiful image.
The photo at the top has non linear filters applied (Color stretching), you can download the final image of luminance and rgb without any filter with only the background gradient removed.
I used Astrometrica to solve the image and Aperture Photometry Tool to extract a list of source from the image with correct celestial coordinates. Than with Topcat I matched the list with the Gaia catalogue to find some missing source on the image to investigate. I found several galaxies and it was interesting to find their characteristics, sadly no unknown objects.
Below, I list some of the objects I found in the image that was interesting to analyze.
