Description

A relatively short 4-hour integration of IC1396 in narrowband, but I still think it came out fairly appealing.  In fact, despite being a SHO mapping, this may be one of my favorite busy star fields and might be even more interesting than the nebula.  There are just so many!

Some tuneup on the HEQ5 Pro prior to the first sessions helped a lot also, providing some of my best guiding in a long time, often around 0.30, and really helped me retain the bulk of my 5 minute subs.

Stacked in WBPP, processed in StarTools 1.9 beta
SHO mapping of R: 50SII + 50Ha, G: 50Ha + 50OIII, B: 100OIII
Emissions balancing/throttling:  100% SII, 29% Ha, 57% OIII
