Added another 4hrs of data to Horsehead, this time in Ha
I really wanted to add some good Ha to this image, so the other night, I managed 12x 20 min subs in Ha, this has really brought out the wispy nebulosity behind the horsehead and generally got rid of a lot of noise, I used the original RGB image for the flame area as this is a different colour and the Ha just made it all red, so the Ha is really in the Horsehead parts only. This must be my longest ever imaging run, 4hrs in RGB and 4hrs in Ha!!
I did a bot of LHE in Pixinsight and came up with this version…..
