Lion's roar

Sh2-132, also nicknamed as the Lion nebula is 10,000 to 12,000 light-years away from Earth in the Perseus arm of our Galaxy. The nebulosity is ionized mostly by two massive Wolf-Rayet stars - WR 153 in the greenish bright colours in the upper left and WR 152 in the blue part of the nebula.

This project was particularly challenging to process because the field of view has so many diffrent colours and brightness of the nebulosity also varies alot - not to mension the rich starfield that can be too prominent. After two days of tweaking I finally achieved the desired results. Also this is my longest project yet, with total integration time of ~31 hours in SHORGB palette in two panel mosaic.
