About this image

I was worried this target might be difficult to find visually, but my GOTO was pretty accurate and I just trusted it despite not really being sure of what I was looking at. I swapped the eyepiece for the camera and was surprised that I had NGC1275 almost in the centre of the frame. Just 50 minutes of imaging captured with SharpCap's Live Stacking routine, followed by .FIT image alignment and stacking with Affinity Photo and gradient correction with GraXpert. Quite a lot of galaxies on show.
