Canon 50mm on APS

Shab Tombs, Oman

This is a bunch of 22x2-minute frames taken through an Astronomik UHC filter at f2.8 then combined (40%) with 21x2-min white light frames at f4 to moderate the star colours. The UHC filter makes all Ha and OIII nebulae stand out nicely, very useful even at a dark site.
