Description

This time I used relatively short exposures (20 seconds) and the highest possible resolution (bin 1x1 with 2.4 um pixels) to try and obtain the highest detail and sharpnesspossible for the given aperture and focal length.
Unfortunately the is some asymmetry in the picture, with the stars on th eleft side showing some distortion.
Could be some mechanical play in the way the filter is set in this particular setup.
