Description

Short 8 hour integration here, basically the only amount of time I could get on this over the course of multiple days. Data came out fairly good, considering the quality of the seeing and transparency here in the PNW in the Winter time. I need to get some more OIII for this to bring out more of the nebula shell and the blue hue in IC444. Hopefully I will have a chance to work on this some more.

After speaking with Matt from CBO, the PN you see in the teal nebula of IC444 is HoCr-1, which was discovered in 2006.
