I posted a teaser of this prior to StarFest but it has been a challenge to get to this. Finally I thin that I have finished the image off.

this was 5hours of RGBHa with Askar 151PHQ and 2600mm. Interesting that the SeeStar for the same time does a good job but it’s really not the same https://cleardarkskies.ca/2025/09/06/ngc6946-fireworks/
