Back from my monthly pilgrimage to Leyburn, focusing on Horsehead this time. Decided to use the OSC rather than the Mono for simplicity sake and take advantage of the dark skies. After about 150 subs of 3 minutes, I whittled it down to about 96 subs with 40 darks. It's definitely one of the better horsehead I've done but I think I pushed the stretching a little too farm. I've also been experimenting with different noise reduction processes on PI and gave GREYC noise reduction a go at the non-linear stage which I think was pretty successful! I still need to get better at creating masks to target particular part of the skies for noise reduction and stretching but its so danged time consuming!

Bonus starless image that's all the rage right now in the community using the new (to me) starnet process in pixinsight.
