Although the raw data was pretty underwhelming, I did manage to stretch the data enough to produce an image I’m happy with. From the Bortle 6 skies that I’m shooting from, I’m sure that emission nebulae like this would really benefit from a narrowband filter. I have my eyes on the Optolong L-enhance as my next purchase which should hopefully cut down on the light pollution.
From this image it’s also clear that my recent astro mod of the D5500 has introduced some tilt into the sensor plane. Stars on the right are in focus, while stars on the left are bloated and out of focus. I may need to open the camera back up to see if this can be dialled out.
