Description

First image with this new telescope. I was unhappy with the blue fringing with my previous "budget" 80mm scope and was hoping that this scope would do better. The Rosette is a good test due to the blue stars within the nebula and I must say that the scope did a very good job with no apparent CA and tight stars. This image is a blend of 60% Ha and 40% lum and I also tried to bring out the subtle blues near the center. The field isn't as wide as it should be due to poor star alignment after a meridian flip. Ha 20x400s, L 10x150s, RGB 8x200s.
