Description

This is yet another test image of M13; I really should allocate time to image it in LRGB correctly. I was intending to collect data on M21, which a low altitude target for my location, but clouds at the horizon wouldn't go away for long enough for me to even plate solve the target. Hence, I decided to see what 5 min expusures on M13 looked like as I've only ever used 2 min exposures on it previously since getting the mono QSI583wsg camera and C14. So many more stars in this, so I now know that at least 5m exposures is definitely the way to go. FYI here is my previous LRGB image, which was also a test run.... M13 LRGB in 2m subs
