Description

after the last year using a series of OSC colour cameras and the optolong light pollution filters I decided to give Mono a try for the first time purchasing the new-ish ZWO ASI294mm and a set on Antlia Narrowband 3.5nm SHO filters and ZWO filter wheel. Took a while to get eveyrthing setup but finally managed around 6 hours last night with ~ 2hours on each filter with 300s expsoures. Carina is well place at the moment for me so made an obvious target.

Stacked and processed in APP with just some minor tweaking in PS. I mpressed with how much can be done with narrowband in APP. I'll process this also later in Startools using the linear stacks from APP but happy with this for a first go, new camera, new filters, new processing etc. Amazing what can be captured in narrowband in a light polluted city with a full moon!

In APP I loaded SII as red, Ha as Green and OIII as blue but also then added SII and OIII as green as well... seems to produce a better SHO colour balance as a starting point. Basic colour APP gradient and star colour processing and HSL selective colour.
