Description

This was an interesting experiment.

I took an earlier wide stack of NGC 346, added a narrower Ha stack of 90m. Expectations were low, but after a few tweaks to the RGB-Ha balance, I was pleasantly surprised.

It's interesting how Ha highlights carbon stars. There are quite a few in this shot, and they're not hard to spot.
