This is my first attempt at Jupiter using a setup that’s primarily optimized for deep-sky imaging: C8 EdgeHD with 0.7× reducer and ASI294MC Pro.
At this focal length, Jupiter comes out to roughly ~65 pixels across the disc, so resolution is clearly limited from the start. I recorded a short SER (~1.5 minutes at ~30 fps using ROI), and stacked the best ~25% of frames in AstroSurface. I’ve posted both the unsharpened stack and the processed version. The Weiner deconvolution probably pushes the data slightly — though it does help separate the bands.
What I found interesting is how strongly image scale dictates the entire outcome. With this configuration, you can definitely resolve the main belts and capture Io cleanly — but there’s simply no room for fine structure to exist in the data.

I plan to repeat this at native focal length using an ASI676MC planetary camera, and possibly push further with a 2× Barlow to increase sampling.
For those who’ve made a similar transition:
At what point did you find the move to smaller pixels meaningfully changed the outcome?
How much practical gain did you see going from native focal length to 2× amplification on an 8" SCT?
In typical seeing, do you find 2× on a C8 genuinely productive — or mostly theoretical?
Interested in hearing real-world experience before I take the next step.
