Despite the full Moon, I had a pretty productive session on Feb 5th.
Plenty of LP and Moon gradients, but the 'save as seen' images came out nicely, IMO.
I'm loving the AT80ED I got from Astronomics. Sure it has some CA, but if one can ignore that, it is a fine performer. Retains focus nicely (unlike a SCT) and the wide(ish) FOV makes plate solving a snap.
Here are the common parameters for the set:
AT80ED(F5.6)/asi294mc-pro(-10C)/SW az-gti(eq)/uv-ir cut
8 sec sub, 300 gain. flats and darks. Flats taken with an LED panel 12 sec sub, 0 gain, 8 brightness, dark flat calibration.

Comet C/2022 E3 (ZTF) 832 sec Near Capella, but just outside the FOV
Double Cluster in Perseus. 80 sec Because of the Moon, I originally was going to shoot just clusters, but found that nebulae and galaxies came out pretty alright as well.
Heart Nebula 480 sec Clearly could use more time on this, but still can make out the overall features.
Horsehead and Flame Nebula 568 sec Always a crowd pleaser, and acquired in less than 10 min.
M31 Andromeda Galaxy with companions. 1944 sec Did fine even with full Moon.
M34 another cluster. 248 sec a quick capture
M42/43/running man 1016sec When in the sky, I always try to get a shot. Earlier in the evening, our geosynchronous spybirds were repositioning themselves. Very common to see this activity in Orion.
M81/82 456 sec
Monkeyhead Nebula 256 sec. My first time with this one.
NGC 891 and companions 224sec. Of course could use more time. With labels showing evidence of mag 12-14 galaxies.
Rosette Nebula 688 sec nice view, although a bit noisey.
