Nice shot, it's great to shoot in the gray zone. A tip—make an aperture mask for the main mirror with a diameter of 125 mm. You'll lose a bit of light-gathering power, but it will eliminate stray rays around the stars. This is because the edge of the mirror is beveled.

Thank you! Yes, I plan to stop down the aperture; the diffraction spikes are ruining it.
