Description

Been a few days trying to process this image in a good way (at least to my eyes). Unfortunely, M31 galaxy is so huge that it doesn't fit all in my fiel of view (800 mm focal), in times like these I think about a litlle refractor at around 400 or 500 mm focal lenght.....hummmmm

Setup used: Altair astro 200mm f/4 newtonian, Baader MPCC, Canon 350D baader modded and self cooled (peltier with cold finger method), EQ 6 mount, autoguided with GPUSB and a 50 mm modified finder with a 2x barlow, stack of 10x 8 min. @ 400 ISO, ambient temperature 20º C
