NGC 2335

The Seagull Nebula (IC 2177), spanning 120 x 40 arcminutes, is as vast as it is faint. The northern “wing tip” is defined by NGC 2335—Just 0.7° to the south-southeast, the magnitude +6.7 cluster NGC 2343.

I managed only 85 exposures of 120 seconds each using the Optolong L-eNhance Tri-Band Deep Sky Imaging Filter, totaling just under 3 hours. Hopefully, I'll get a clear night soon to add more data. I'm quite happy with my first attempt at capturing the Seagull Nebula with my Redcat.
