Description

We used SCT8 Celestron with focal reducer, EQ8 mount , Atik 383L + monochrome camera, AOG Celestron, Starlight Xpress guidance camera, AstroArt 7, Cartes du Ciel, PHD 2 Guiding. The frames were taken on the evening of December 5 at a temperature of about -7 degrees Celsius. That's why I had a problem with the ice that was formed on the corrector plate. Now I have a warming system, but unfortunately I did not have a clear sky and it looks like it will not be too soon. More parts in the picture was affected by the ice crystals formed so we made small crops from the 29 images. The 30 second exposures images I used for the animated GIF image.
