Equipment:
C11" EdgeHD with ZWO ASI260mm and Chroma narrowband filters
Description:
A classic planetary nebula, Messier 57, aka, the Ring Nebula, seems simplistic looking until one tries to capture the faint outer shell(s). Under my Bortle 7 sky, I used Ha and OIII narrowband filters to capture 30 hrs of data of the faint outer shell(s) while preserving the bright core from being blown out. RGB stars were added in. Seeing was good but transparency was a problem with high thin clouds. This is a processing challenge. The C11" EdgeHD was used at f/10 along with a ZWO ASI2600mm camera (0.27 arcsec/pixel).
