First light Askar SQA55 without filters 14/11
And first light of Antlia ALP-T Ha+OIII 3nm filter 15/11
Then stacked. Stars unfiltered.
Shot in post-sunset clearings between snowfalls, if it wasn't necessary to first-light the equipment, wouldn't even have set up.

Added a couple of hours of accumulation and removed unfiltered stars - they look very strange on the filtered background.
