Test of Mintron 73S85HP-EX-SW-R deep-sky colour integrating Video camera with a 6" f/5 refractor

Integrated image
On March 1 I tested the Mintron 73S85HP-EX-SW-R deep-sky colour frame-integrating video camera using a 6 inch f/5 Helios achromat with a 0.5 focal reducer and a UV/IR cut filter. The live view was incredible and, unlike with an 80mm refractor, was almost as good as the image obtained by summing 100 integrated frames with dark-frame subtraction in Astrovideo.
