Description

An opportunity to test the luminosity of the fully open Samyang lens under a nice sky by city standards (rain and wind improved transparency).
Unfortunately I still do not have the correct spacers necessary to achieve the best spacing and when keeping bin at 1x1 with the small pixels of the ZWO ASI 183MM camera (particularly without a narrowband filter), this creates aberrations on the stars, hence I had to intervene a bit heavily on their shape in post-processing.
