Description

In a wide field view this target should be called 'The Tadpole Nebula'.

Bortle 4 Skies but cold and damp air so guiding was 1-1.3 arc-seconds (2.4as/pixel so not terrible though). Moon was almost full and around 40 degrees away so also a bit challenging from that perspective.

This target is in the midst of a very dense star field so most images don't highlight the nebulosity well as the stars hide/distract from it. I have reduced the stars and added hydrogen-alpha data to the image to bring out more of the nebulosity and dark dust lanes. I am happy with the result. 

I also uploaded a close-up of this image here: https://www.astrobin.com/p0t0my/
