Recent work in Cygnus- still working towards a 6 panel mosaic of the Loop. I have been shooting the Hydrogen and Oxygen data from Chattanooga while shooting my LRGB data from Marathon remotely. I've been using a 3nm Hydrogen and a 6nm Oxygen filter to do my work. Results have been pleasing to me.

I hope to add a 3nm Oxygen filter soon.

Thanks for looking- Details:
