I've just downloaded Registax6 and was trying it with my new ASI120MC and sharpcap. The problem I'm having is that registax6 won't open the AVI files that sharpcap produces, and I'm at a loss to work out way.
OK.
I've been using AS3! with 8Gb files (both AVI and SER) from FireCapture.
Then importing the final image into Registax for wavelets etc.
(The cameras are the ASI 174 and ASI 183MM)
