With a gibbous moon up, I wanted to image this small bright object. I used a 2x converter on the 10 inch scope with the EOS Ra. No filters. 8 x 2 mins ISO 800. Off axis hand guided. Wind buffeting made it especially challenging. 2800mm focal length is pretty fussy and unforgiving. This is a small full res. crop.

Thanks all. If I balance the scope so its slightly east heavy, it keeps the drive worm gently engaged to minimise backlash and it tracks surprisingly well. I use Sharpcap polar align function to get it within 10 or so arc secs, so no dec drift or correction needed. The off axis guider shows sharp round stars with the Basder Coma Corrector in place. Any periodic error is gradual and correctable. The guide star sits there nicely in the virtual reticle. Last night the wind was the biggest pain. Had to throw out some subs so affected. Just so glad to get a deep. sky image after a huge run of inclement weather.
