Vicinity of the star Sadr. NGC 6910 NGC 6888

First light with the new lens. I cropped the edges, the flats were poorly taken, and there's a strong gradient in the sky. At first, I shot at ISO 1600, but after stacking a few frames I realized the stars were blown out, so I lowered it to 800. Stacking was done in Siril, processing in PixInsight. I placed a 2-inch filter in front of the lens, resulting in an aperture of around f/2.9–3. Of course, the nights are still very bright—the software shows it's twilight.
