Description

With no astronomical darkness anymore here in Cologne I decided to use a little bit of time to add some OIII to y existing NGC 7000 data. Quite a bit of work to now get six channels together but I enjoy the result.

Accidentally I had Gain still set at 300 for the OIII from a little Jupiter session before but I managed the noise by combining Lum from L, Ha and OIII all together.

Let me know what you think!
