Description

My second image from 2019's season, another fight against clouds...

I insered some diffraction spikes on bright stars because micro lens reflection (a deffect in this cameras), so I guess spikes more friendly than micro lens reflection. The spikes was generated with Star Spike Pro plugin.

I hope you like it!
