I did this shot of the Veil Nebula using the Epsilon 180Ed , ZWO ASI2400MC pro One Shot Colour and Askar Dual Band Ha/O3, remotely from Spain
I am just gobsmacked how much I was able to bring out for such a relatively short amount of exposure... and on a OSC no less!!
These Dual Band filters reinvents OSC imaging in my opinion.
Exposures were 56 x 300s sub exposures 4.6 hrs total for each panel. (Two Panel Mosaic)
Thanks for looking
