Description

This is a reprocessing of my data from 2017. I tried to fix the effect of the field rotation, which made a strong and strange reflection (on f/2!) around the bright stars even in 60 seconds. The correction resulted the multiple spikes around Polaris.

Additionally I have uploaded a starless version too.
