larkinsen 1.9 was a massive update which pretty much sorted everything. And it works. Done many many hours with it. With v2 I've spent more hours setting up and trying to fix issues than imaging so gave up on it. At the moment the only thing v1.9 needed was an up to date target list (eg recent comets).
If you want to update v1.9 and give something genuinely useful, give proper planetary imaging exposure controls and allow saving as images, I still use astroberry for this as it allows much better control, custom ROI thus using the high speed FPS frame rate of the cameras as advertised by the company and not saving as standard 25/30fps video which doesn't freeze the seeing so well.
