Description

This is a 10 years old image. It's the sum of 90 exposures of 30 seconds each (unguided) with a C8, a 6,3 focal reducer, a Starlight MX7C, taken from my home terrace. Everything on top of my venerable GPDX. Image has been cropped to reduce the amount of gradients coming from camera amp glow. I have done some little bit of reprocessing (unfortunatelly on the jpg, as fits files have been lost) to adjust color and do the cropping. Hope you like.
