So, I haven't really been able to so any astronomy for the past year and a half.  Had my first child, and with that and my teaching schedule, it doesn't leave much time for anything else.  But, decided that I needed to focus just a bit on the old hobby, so opened up the observatory, and set things on M52.  For some reason I like this cluster.  A widefield shot is like trying to play whack-a-mole with nebulosity.  And, of course, the Bubble being in there is an added bonus.  Because of light pollution, I have rarely tried LRGB, but I decided that, since I was going to do all of this fully automated, I would just let the light gather for days, and try and get a workable signal.  Since it was an open cluster, it worked pretty well.  I also tried to enhance the Red with Ha using Pixinsight's NBRGB script.  Overall, it worked pretty well.  I think there might be an overall very slight blue hue, but that might be my monitor. 

As for processing, I went very light on it.  I sadly don't have hours to spend on processing, so I just accepted the things that I did not have time to change.  The specific details are in the Astrobin description.

I am certainly open to any comments that you all might have.

 

Cheers,

John

paribus,

 

This is just the sort of image that I really enjoy, outstanding data

capture, light processing.

 

Spacing on the reducer/flattener needs a bit of adjusting, probably

widening the gap a bit, judging by the corners.

I shall try moving it out a mm or two.  I have experimented a bit with it, and it's just being stubborn.  It originally fit a much older 700mm f/7.1, so I have not really had many illusions that it would work perfectly for the 71gt, but, since it gets such wide fields anyway, losing the edges never made much of a difference.  Of course, with a field so full, it suddenly became one :).
