Javed, a 25mm telescope eyepiece is mounted on the camera via an adapter,then mounted on the telescope of which I use two, the 1250mm is my favorite because it is very portable. An electronic shutter release is used with the tracking motor engaged. Shutter and F stop is set manually.
Difficult subject matter and so far away, well taken. This is something I like to photograph, some technical detail would be nice, how did you manage to shoot this? Thanks for your comments on "peace On Earth".
