Imaging Session – Oct 19/20, 2022

The middle of a work week and I go and pull an all-nighter imaging session.   Weather was too good to pass up  the chance.   I must be insane or obsessed – or both.   lol

It was worth it.  I got some good data and was able generate these 3 images so far. They’re still in the preliminary stages, though.  Each were essentially saved as seen from SharpCap v4’s LiveStack module.   I just did some basic adjustments in PS to make them pretty but are not the final product.  I’ve been so busy with work and also recuperating from a bout of some kind of a stomach bug that I haven’t had time to devote to make final renditions.

I got 3 hrs for M31 and about an hour each for the Orion and Horse Head Nebulae.    I used 5 minute sub-images for most of this session.  I little too long for my mount’s sometimes iffy guiding, perhaps, but mostly correctable in final post-processing, which I will eventually get to.

Update:  Finished the Orion Nebula / Running Man post-processing job and also work on the very first image taken during this session, the Eagle Nebula.  I actually got the Eagle going first and then put it on the back burner, since I did not have very much time on it.
