Have just given up for the day. I could see by eye some prominences and surface features, but not really got anything out image wise. My intent to use a DSLR was scuppered early on when I found out the focus point is nowhere near where it needs to be to use a DSLR. Had to improvise with what else I had... The least worst follows:

Image
Output from Meade LPI, resized 50%. That was easily in range of the scope's focus. Took me a while to figure out the software settings to get anything out that wasn't clipped on either end. This just about showed some surface variation, but nowhere near as good as naked eye showed. I also found out it is a right pain to centre the image on the sun hence it is hiding in the corner a bit.

Image
This is the output from HX9V pointed at the eyepiece image, cropped significantly and resized down. I think there are hints of prominences trying to show up here, but no surface details. I think the exposure here was relatively higher than with the LPI, hence clipping the surface details out.

Image
And finally, I had to get the "laptop stand" out :mrgreen: The laptop screen struggled in sunlight though.

I gave up not long after the above, as the sun was obscured by some trees from late afternoon and I don't want to move all the kit out in front of my house for the last of the sun. Maybe I can find the eyepiece holder for another go tomorrow.

After some research using eyepiece projection directly onto sensor seems to be my best option, and I'll go for a 17mm Hyperion eyepiece which, with their optional fine tune rings, also works as a 13, 11 and 9mm too. Also add T-ring extensions which they suggest increase the "projection factor". Hopefully some combination of the above will give something usable!
