The annual M27


Recommended Posts

Finally managed to get out imaging with the rig in the observatory last night, events have prevented any astro for a long time.


This was just a reminder session of how it all goes together and works. It was supposed to be M13 but the balance on the scope must have been way off on that side of the meridian as the PHD dec was all over the shop. I slewed to M27, recalibrated and the PHD graph was flat lining so without further ado I set the gear churning on that for what now seems to be my annual autumn M27 :)


Scope - WO FLT98 with WO Mk4 AFR, IDAS LP filter working at f5.2

Mount Celestron CGE

Guiding - Finder guider with QHY5 direct to mount

Camera - Atik 314l+ OSC running at -12 C of ambient, equating to -2 actual.

A mix of 3, 4 and 10 minute subs totalling 65 mins. Subs were extended as sky darkened


Stacked in Images + 4 and final process in PS7


Now M27 is out of my system and I remember how to do things, I shall try something a little less mainstream next time.
