Here is an image of Jupiter, taken around 6am on 15 Feb with my C8, ASI120MC, +ADC, processed in Registax6 from around 30% of 3000 frames.
I am fairly pleased with it considering that the altitude of the planet was only about 12 deg. and the seeing looked bad when I tried to focus on a star. And it shows the Great Red Spot.

I had another go at imaging the shrinking Mars, this time without and with a x2 Barlow lens. The results are better with the Barlow, which is what one is led to expect. For whatever reason (probably bad seeing and/or low planets) when I tried a Barlow previously it just made the blur bigger. Equipment: C8 SE, ASI120MC, x2 Skywatcher kit Barlow element screwed directly into 1.25" barrel of the ZWO camera. This does seem to give x2 in practice. I did not use an ADC on the grounds that I shouldn't need one with Mars at an altitude of over 40 degrees.
3000 image video captured with Sharpcap. Processed in Registax6. I found that the Sharpcap exposure histogram did not appear to work on such a small image, so had to estimate the exposure. Yes, optical ADC correction would be better, but the dispersion seemed very small. Blowing up the image x2 in Registax showed a small colour fringe, which I took out with a single point of correction.
The images show some surface detail though the contrast is low (if you are using a flatscreen try viewing from below: 🙄) Mare Sirenum, with Mare Acidalium just discernible foreshortened at upper right.
