After reading a terrible weather report for clear skies I happened to notice a semi-clear sky outside at around 9 O'Clock last night. So I did my normal setup with my dad's 300mm f/4 Nikon lens. I was keen to see how good the optics were. I spent ages setting up polar alignment on my astrotracs but after an hour of tests for alignment and focus and exposure, I homed in on Andromeda. I figured out how to modify my Canon 400D so I could IR remote from the warmth of my living room. Took 25 x 1 min , plus 3 x 2min, plus 1 x 3min and 6 dark frames. Set lens one stop down, f/5.6 and at hard stop infinity (you have just got to love these old lenses) and finally I stacked and processed in photoshop. Here she is. Enjoy.
