I have only ever used my Sony a6500 mirrorless camera for any kind of astrophotography. Obviously, most people use DSLRs or mirrorless cameras for DSO, but most people seem to use ZWO cams for Solar System imaging. The uncompressed video, high framerates, and such, give the planetary webcams an advantage. The sensor seems to be smaller in the webcams, but I don't know how that translates into pixel size. The Sony a6500 has a pixel size of 3.89um. Are these small pixels in comparison to the ZWO? I've always reasoned that smaller pixels give higher resolution, but gather less light. I don't know how flawed my reasoning is. Nonetheless, this is Jupiter at 14° above the horizon a few nights ago with my SkyWatcher SkyMax 180, captured with my Sony a6500. I'm using 4k video, and a digital zoom of 4x to crop in on the planet. Then I'm resizing the image down in post to give it a sharper feel. This seems to be working. Does anyone else here use a DSLR or mirrorless camera for Solar System imaging? What tricks work for you?
