Description

Hi everyone, I am still working on finding that sweet spot for the L-eNhance filter. I initially thought long exposure worked best. While this did bring out more of the low red channel I was still getting a weak signal to noise ratio. I've been trying a large number of shorter exposures and it seems to work well for brighter DSOs
