Description

I thought it would be interesting to present the Seagull nebula in an unusual way, using 3nm Halpha and  3nm NII filters. Yes there is a difference between the images from each filter, with substantial overlap as well. Not sure I'll use this approach again but, to me, it was interesting and certainly worth the effort.
