Thank you Ivan, IR filter in my 300D is just removed, thats why I use external 2" Baader UV/IR blocking fiter.
Yes I use 0,8 X Televue FF, which is suitable for refractors with focal length 800 -1000 mm and I have to say Im very satisfied with it.

Radek,
Beautyful images! These images looks like a true ccd images, not only a
DSLR images! Great!
What type of 300D do you use? Hutech modified, or different?
Did you use a FF (field flattener) for the TMB?
