Description

A HaLRGB image taken with my new Rokinon 135mm lens. This lens has much less (none?) CA than my previous lens, a Canon 135 L series. I've been using it wide open at f/2 and it has quite good stars across the entire field. I may stop it down one stop for slightly sharper stars in the future though. In general, an excellent lens. 25x60s L, 15x400s Ha, 8x100s RGB with Ha blended into the R channel.

I did have some problems with pink Ha regions as I had stretched the RGB too much so redoing the RGB with a less aggressive stretch helped. Plus, I think my RGB exposures were too long as star colors are lacking due to saturated stars. It's always something.
