Lambda Centauri in 3nm NII

This is an image from 25x16 minutes exposures in 3nm NII. It took all night to collect, seven hours in fact.

It was mainly an exercise to eliminate any noise in the very dim regions.


I already have seven hours of RGB data and will collect HA, OIII and SII.

My system can really only usefully collect from the East to two hours after the zenith. The light pollution in my western sky is far worse than my eastern.

Below is also a crop showing the Bok Globules.
