Description

The Twin Quasar is an object I've been looking forward to catch with my 8" scope for a long time. The two images of the Quasar appear to us under a distance of only 6 arcseconds, generated by the galaxy YGKOW G1. I was curious whether my simple system without guiding would be able to resolve that "double" quasar. The stars are a bit elongated due to 30s exposure time at 1000mm FL, but the two spots are clearly separated!
