Seeing was absolute rubbish but I wanted to test out a theory. I made a 60% aperture mask for the 11" SCT which works out to approx. a 5" aperture less the fairly big central obstruction.

Even though the seeing was sub par; 2-3/10 tops (I only saw a very brief 2 second period with seeing of about 8/10) I'm now starting to see granulation & surface details. Can't wait for nice seeing to test this out further.

Cheers.
