Featured Photograph

Aurora Borealis from Haukland Beach

Who doesn’t love the North America Nebula (NGC 7000)? On really dark, transparent nights you can actually spot it by naked eye close to Deneb in Cygnus. What we tend to forget is that this enormous start forming complex, about 1,700 LY from us, also includes the Pelican Nebula (IC 5070) and additional extended nebulosity and dark dust lanes.

This image, taken with a TMB-92 f/5.5 refractor and modified Canon 6D and IDAS LPS-V4 filter, covers about 90% of the brightest portions of this complex. This mosaic was composed from 8 x 2–3-minute frames shot at ISO 3200. Images were stacked in Affinity Photo and then processed in Photoshop CS6.
