Description

This target is a bit small for the 4" APO, but there is a lot of dust and background gas that leads for nice composition. I've used the FORAXX palette with some palette modification which worked well on that target. It is also a relatively dim target. With close to 40hours on this target (shot over 5 nights), this is my all-time record for total exposure.

I've gathered RGB for the star substitution and it is comical how weak the broadband signal is even considering RGB accumulation time. Those Antlia narrowband filters are really doing some work.
