NGC188

[Graham Darke]

Imaged over 2 nights on 7th and 8th January from my Bortle 8 home site. Due to the closeness of this target to the NCP my ASI Air plate solving software had a tough time on both nights. It just couldn’t centre the target so I did it manually and got lucky that the frames were pretty close. I ended up stacking 142 x 90 seconds. I rejected quite a few of the acquired frames that were ruined by passing clouds. Details:
