Took the Tal apart and cleaned the optics after two years of use. It really needed it as focus was very vague. Took this test shot of 47Tuc with the Moon present (90%+).
Details
Canon 5DH, Tal 200k with Hutech focal reducer so 1790mm at F9, Hutech LPR filter, 2x8 min at ISO 400. Processed with Images Plus and Registar and adjusted for levels in PS.

Hi Bert,
Well composed image. :) There are some elongated stars throughout the image so not sure what happened with tracking/guiding.

I'm guessing you don't get any dust donuts now the optics are clean. You could perhaps take a few flats to confirm.

Nice image Bert,

Well done for just 2 x 8 min exposures.

Watch out for Mike because it's a lttle red bias....

Tweaked a few settings and did not have intermittent cloud ruining autoguiding.
All the same as below except 4X16min.
