Description

Used gain 0 for maximum dynamic range. Kept exposure time as long as I could without saturating too many pixels in order to reduce the number of subs collected.

Processed using PI:
SPCC
BXT
GHS
NXT

When using GHS I took care to use the "Protect highlights" slider during stretching in order to minimize bloating the brighter stars.

Note: I did not perform ABE or DBE there was plenty of target signal over the entire frame - background extraction was not required and may have removed actual signal if I had used it.
