Mario:

Nice lens and lots of stars.

Two days ago I took images of the Lyrae constellation with a 135mm lens, but I posted only a small crop (at full resolution with a D7200) of the Vega and eps10/20. The question I asked was: Do star diffraction patterns distract. Your Sigma 105mm f1.4 at f/2 apparently has sufficiently rounded aperture blades, that Vega does not show a diffraction sunstar, or maybe not in your posted jpeg version.

Why did you down-sample the D5600 24 Mp? At full resolution you should be able to resolve the Ring Nebula (M57). Shown below is the M57 area with my setup. M57 is in the lower left corner. My image almost missed it.

Taken from my Bortle 8 backyard.

Cheers,
