SH2-188

Imaging under a full moon is never fun and this RC8 seems to pick up a huge gradient across the top of the image when the moon is bright, it probably took longer to sort out than the rest of the processing!

Anyway..... 4 hours of Ha and 4 hours of OIII in 15 mins subs with 30 mins per channel RGB for the stars.

Some more details on this target here. It's a planetary nebula that's travelling very quickly through the interstellar medium, forming a shock front on the left and leaving a faint tail behind it. I first came across it when I spotted a tiny arc in one of my widefield images and wondered what it was.

Very nice object and image! 

I do feel it could be sharper? But that of course could also be image compression for the web?

V nice, not seen that one before.

Nice job.

There is some nice SII in there (once the moon is out the way) which is a bit brighter than the OIII as shown in this post
