On 29 August I was able to get out again for another side-by-side test of the Canon 700D against the ASI 224MC. The skies were absolutely clear, jetstream levels in the teens and there was no surface wind. However, for some unknown reason the seeing wasn't great but still good enough to get some comparisons.
Based on previous discussions with Darryl, I've taken a lighter approach with my sharpening scheme with Jupiter which has produced a less harsh effects on the final appearance on the planets. Both images were taken with my Celestron Evolution 6" SCT with 2x Barlow, processed in AS!3, sharpened and auto-colour balanced Registax with final touchups in Photoshop Elements. The first image was taken with the Canon 700D image and used 25% of 10000 frames at 20 fps and f26, the second using the ASI224 with 75% of 38639 frames at around 214 fps and f22. There was about a 20 minute gap between the two captures while I changed over cameras, re-acquired the planet and re-focused.
I think there's a pretty clear "win" to the ASI224 on this occasion, the cloud bands appear to be sharper and have more of a "natural" look and feel to them, while the DSLR images never really showed much promise. Maybe there were other factors at play, changes in seeing, imperfect focus, etc.
