NGC7000 and IC5070 in Glorious Technicolor

Cygnus is a beast of a constellation. There’s no denying it, targets everywhere you look and this set is such a perfect 200mm frame

NGC7000 and IC5070 have strong Ha and O3 gas emissions with incredibly strong Ha filling the entire surrounding area

This image reflects this with the blue areas showing the strong O3 and red being the strongest Ha with the purples being a blend

I know it’s a strong image and won’t be to everyone’s tastes but it’s good to push at your own sensibilities and see what comes of it. Never stop testing and learning
