20080824 Sun (DSLR)

I've tried to setup my Borg 45ED II again today, to test the DSLR. This time, I tried in both white light and CaK.

Telescope: Borg 45ED II without extension tube
Filter: APM Herschel Wedge + ND3 (white light) or Baader CaK (Calcium K)
Camera: Canon 450D

The combination barely reach focus, but since the image scale is rather small, I would use a barlows both to increase the image size and at the same time, allow more back focus. Therefore, I've used a Tele Vue 3x for the images below.

White Light, 1558 (GMT+8):-

CaK, 1604 (GMT+8):-

CaK, 1605 (GMT+8), longer exposure:-
