NGC2239 Rosette Nebula v2.1 including Ha data

This is my first attempt at taking and using narrowband within my LRGB images. This builds on a little LRGB data already taken (version) combined with additional Ha and RGB data taken last night. There is still very little data here as I have a limited window of visibility before it goes behind the house.

Using the Skywatcher Esprit 80 with the ZWO ASI1600MM-C, the ZWO LRGB filters and the Astrodon 3nm Ha filter. All images taken at -20C, 300 gain and 50 offset.

During processing I discarded all L data as it was weak in comparison to the Ha data, even when blended. I have also blended the Ha data into the red channel using the tutorial on the Light Vortex Astronomy website. 

Ha: integration of 35 x 30s (new) and 22 x 60s (new)

R: integration of 33 x 15s (original) and 10 x 30s (new)

G: integration of 39 x 15s (original) and 10 x 30s (new)

B: integration of 30 x 15s (original) and 10 x 30s (new)

Image captured in SGPro and processed in Pixinsight and finished in Lightroom.
