Description

3 panel mosaic taken over a week in Panamint Valley. Had to go drive back out to the desert to re-do the first panel (on the left featuring Mintaka) as the seeing was so horrible the night it made everything a blur, even at 450mm FL! 

This was my first time doing straight RGB, usually I go for LRGB but I figured there is so much color resolution here I'd like to devote the imaging time I had to capturing that. 

I have started using Vincent Peris' multiscale gradient removal method to yield fantastic results. To do this I took another widefield version of this area with my Canon R8 and a 180mm lens. Typically fields like this are a nightmare for DBE as there is really no "neutral background". Imaging from a bortle 2 location helped a lot but for mosaics keeping the airglow and lp gradients out are a must. 

I had originally planned on adding a night of HA data to each frame but after initial processing I decided against it... I think it would have overwhelmed the rest of the image.
