Sionyx Opsin and Rix ST6 - Night Vision and Thermal Fusion (Kinda)

This video was my best attempt to display what happens when I try to fuse the take from a Sionyx Opsin and a Rix ST6 thermal. This is not perfect because I'm not a video editor, and syncing the two is ... difficult. The ST6 take is at 70% Alpha because it's far brighter than the Opsin take in most scenarios.

Conditions were mostly clear, no moon, some light from the city and across the river - very dark. This was my fourth attempt at this, and the first that was mostly successful.

The primary problem I've run into is that the ST6 and the Opsin apparently have differently sized screens (different size pixels?). My ST6 take appears down and to the right of the Opsin take, and is ... wider? It's difficult to describe. I tried numerous different positions for the ST6 in relation to the Opsin (the Opsin is harder to move, I'll do a different video showing the setup). The only thing I can think of is that I need to move the ST6 forward, which is what I did to get this - but it's still not ideal.

I think the optimum setup would be taking the feed from both sensors and merging them electronically into the same display, with the ability to scale and adjust as needed. That, however, would require a system to do the merging, and potentially increase latency. This also would require interoperability that doesn't exist at the moment, and might be difficult to establish.
