Description

There was a couple of first for me in capturing and processing this image. First time shooting in monochrome, using narrowband filters, and processing using only HA and OIII. And while the image could be greatly improved, as my backspacing was about 20mm off and I decided (forgot) not to use any flats during calibration, I am stilled pretty pleased about how it turned out as it surpasses anything I've been able to do with a digital camera.
