Description

Here's a 3-panel mosaic of some of the emission nebulae in Cygnus spanning NGC 7000 to SH2-115. This was shot with two different dual-narrowband filters, Ha/OIII and SII/Hb. In this case, I used SHbO for the RGB mapping and Ha as a luminance layer. Turns out there's not much H-beta in SH2-115... but it did make for an interesting blue/red/purple composition. 

This was a total of about 55 hours integration time divided about evenly between the three panels and two filters. Processed in PixInsight with the stitching done in APP, and final processing again in PixInsight.
