Summer with the Colour Deep-Sky Mintron

Colour Deep-Sky Mintron imaging

The MTV-73S85HP-EX-SW-R colour deep-sky Mintron was used at the Prime focus of an f/4.8 10 inch Newtonian to image M57 and M13 and with a 0.5 focal reducer for M51.

The Video was recorded to DVD including dark-frame video and then played back through a capture card and recorded by GStar as an AVI capturing a frame every 5.5s. The dark frame was scaled and used in Registax to correct the registered and stacked frames:
