   Another pic that's been in the backlog for a while. This is NGC 7139, a.k.a., the Small Cluster Nebula or the Rosebud Nebula. This is a reflection nebula about 3,300 light-years away, and captured in "true color".
   
   I was hoping to collect a lot more data on this one, but the weather has thwarted me (at least for this year).
   
   Details:
   - Celestron 8" EdgeHD (w/ 0.7x reducer) + ZWO ASI585MC
   - 126x180s (6.3 hr) UV+IR cut
   - Bortle 6/7
   - PixInsight w/ BlurX, NoiseX, and StarX
