I had gone out to my clubs dark site for several nights to work on a widefield mosaic of the Orion/Gemini area, once that set I had some free time to shot a few objects I’ve always wanted to go for. I noticed Omega Centauri was barely above the mountains to the south around 1 am so I pointed the 6″ and snapped away. Seeing was excellent that night so even though it was very very low the color wasn’t too washed out.
