Description

The subs was taken by Mr. Niels Haagh in the city of Ganloese, half an hour drive by car from CPH DK.

The TTS 160 Panther mount with the telescope rOTAtor was used.
Celestron C9.25 Hyperstar F/2 scope/setup and camera ZWO ASI071MC pro. used (my camera and 2" filters :-)
A 2" Baader UV/IR block filter & a IDAS LPS V4 filter (used on the 300sec subs) was also used.
A Televue TV-60 scope used for guide purpose, the tracking scope was ZWO ASI224MC.

The PS, CCDStack2, RegiStar processing part was done by me, and Niels H. did the calibration & stack of subs in PI.
