IC1318 and friends

You know some nights when everything goes right, and all you really remember is the imaging? Yes? Then you also know the soul destroying, life sucking nights where a long list of things that worked just fine last time decide to conspire against you. Last night was the latter option. I wont bore you with details, but I nearly packed up at 11pm and went to bed.

Thankfully (almost) all the problems went away after I rebooted my laptop, so I managed to get everything working, left it running for ~6 hours, and still went to bed  🙂

Seeing wasnt great, a fair amount of vapour in the air, lit up by the moon, but it was quite still in the sky, breeze free on the ground… and bl__dy cold! Not “winter” cold, but autumn has definitely arrived with the fresh mornings leaving everything covered in dew.

Mount: EQ6 via EQMOD
OTA: Borg 77EDII @ f/4.3
Guiding: SW ED80 + SX Lodestar + PHD
Imaging: Starlight Xpress M25C + MaximDL, 24×900s, Astronomik 13nm Ha (101 bias, 101 flats)
Stacked: DeepSkyStacker
Post Process: PSCS2

Note: the lower right corner in the mid sized image shows some odd curvature, which I pretty convinced is due to me overtightening the front tube ring on the Borg and pinching the objective. Next time out, I will have to keep an eye on that.
