Andromeda Galaxy (HaRGB)
My first attempt to create a HaRGB image. For the occasion I chose the magnificent Andromeda Galaxy and took the Newton 150/600 out of the closet that I hadn't used for a very long time.
The Newton now seems well collimated but unfortunately I have a problem with the secondary which seems to be tensioned and therefore causes a somewhat annoying astigmatism on the stars...
Special thanks to Valerio Avitabile who helped me with advice that was very useful!
Beyond 1×, the image is enlarged without interpolation, showing the original pixels as they are, so as not to alter the details of the photo.
