My first decent RGB stack, I'd like to collect more. A third of the frames were rejected due to haze. But this is the BTO, you could even shoot it with a shoe.

Processing is light, no star separation, no fussing with layers. Just RGB combination, gradient removal, noise reduction, and stretching. That's it. Didn't even touch the curves to avoid eye strain. The center is blown out? Well, that's because of the exposure.
