Friday the 13th Imaging Session

Normally I avoid doing anything on Friday the 13th.  lol.  But, since astronomical time is Greenwich Mean Time, the 13th ended at 6:00PM CST, so I was good.  Ha!

The Orion Nebula and Friends. 37×2 (core,) 22 x 300 sec, Gain 11, Offset 17, QHY183c at -20C, Astronomic L-3 UV/IR filter, TPO (Askar) 180mm, F/4.5.

I imaged 3 objects this night. One was the object above, the Orion Nebula (and friends,) one was the Flaming Star Nebula and I shot about 2.5 hours of Comet C/2022 E3 (ZTF.)

Equipment used was an Askar 180mm F.L., F/4.5 scope (40mm objective,) an Astronomic L-3 UV/IR filter and a QHY183c camera, and an Atlas EQ-G with EQMOD.

Here’s the Flaming Star. I missed the focus on this. I threw away several processing attempts before salvaging what I could for this display image. Oh, well… next time.

The Flaming Star Nebula (and friends.) 33 x 300 sec, Gain 11, Offset 17, QHY183c at -20C, Astronomic L-3 UV/IR filter, TPO (Askar) 180mm, F/4.5.

Next, after waiting till 2:30-3:00 AM, I took images of Comet C/2022 E3 (ZTF).   It is small and still kind of dim, but has a long, faint tail.  I have two data sets  with about an hour each of exposure.
