Description

Back to Hyperstar imaging! This time it's the dark nebulas B347 and LDN 889 in Cygnus. As usual, it's difficult to achieve good collimation and focus with the Hyperstar. I had less issues with a smaller sensor, but the full frame one makes it particularly problematic, so even after cropping the image, corners are horrible. It's especially visible on M29 on the lower right.
