Description

Quick star test after collimation of my new telescope. Overall a big improvement compared to the stars from my refractor! The lower left corner shows some tilt, still need to work on that.

The faint red planetary nebula on the left is Minkowski 1-18 or PK 231+4.1, an object that is rarely photographed.
