Description

Quick test run with my new CEM60 mount - 60 second unguided subs. So far so good! Now just need to sort out my OAG focusing ...

[Edit] Revision with guiding for comparison. Still having issues with my flats resulting in uneven gradients that I can't seem to correct - had to cheat a little and clip the background to hide the flaws. :)

With guiding this time (for comparison)

E

Still fiddling with the processing :)

F

Testing out a couple of new techniques (such as PCC and ArcSinH) on the old data to try to improve the overall star colour. But still having to clip the background to cover the issues with flats and gradients ... time to let this data rest I think :)
