I’m thinking of acquiring a Raspberry Pi HQ Camera for autoguiding using PHD2; it has (from specs) decent sensitivity, capacity for binning and raw output, 12mp resolution, possibility to remove the IR filter as well, better at long exposures than Pi Cams v1 and v2. It does gave a rolling shutter however.

With an aftermarket 25mm c lens, it’d be equivalent to a 350mm lens on my crop sensor Nikon, and the 25mm lens is pretty fast at f/1.6. Whole thing would cost about 75 USD.

Any thought about this setup? Beats acquiring a dedicated guide scope or guide scope+cam, although a c-to-t mount exists if it is felt a guide scope would be necessary, and it’s be pretty easy to mount on the scope (straight-up 1/4 screw mounted on the ring) or on my astro dSLR body (hot shoe to 1/4 adapter). It seems to be supported by PHD2, but any optical or indi-related reason not to go for this setup?
