Description

Project with Paul Kummer and Peter Woods.

Apart from old Telescopic Ha for the Cigar, this is all Samyang 135 data, shot wide open at F2 onto a TS 2600 OSC camera. Avalon M Uno mount. 3.4 hours in 3 minute subs.
When I compare it with the time and effort taken to catch less IFN than this in a Tak106/CCD camera, I can hardly believe it.
