Description

Accumulating time on this one is slow going - can only start after midnight even if the weather cooperates 100% (which it hasn't). Staying up until 4am isn't as easy as it was many years ago!

After two half-nights just enough L subs to make drizzling worthwhile but a bit short on the colour channels. Hopefully I'll get the chance to add some time to this to cut the noise down before summer nights finally slam the door in my face

Having the IDAS LPS-P2 filter in front of all the LRGB filters is becoming a bit of a pain and cutting the R channel intensity quite a bit. Might see about replacing the L filter with a 36mm LPS if I can justify it with the amount of broadband data I tend to collect....

Description: Just enough luminance subs now to make drizzling worthwhile - could do with another couple of nights (can only start after midnight so half nights strictly-speaking...) to cut down on the noise but whether I'll get them is another matter!
