Just going through some old data and I came across this one that I captured on NOV 9 of 2015 using an Astro-Tech AT65 Quad Astrograph that had been returned to the manufacturer as faulty and then sent to me for troubleshooting, this is only 3 x 180 seconds each LRGB and using Optolong Filters. I found no issues with it in fact I was very impressed with the optics, a perfect combination using the very sensitive QHY23 Mono CCD

The Double Cluster in the constellation of Perseus lie very close to us at only 7500 light years and is one of the most popular targets in the Night Sky for amateur Astronomers and imagers, a perfect object for testing a refractor.
