Hi Doug,

I have a Sony A7III and trying to make it work with SharpCap. Are you making your driver public ?

thanks

Hi, sorry for long delay in responding - yes, driver is open-source, is known to work with SharpCap, and recently gained the ability to support both the 32 and 64-bit versions of SharpCap - here is a link to the wiki, it has links for download/install and various other things like troubleshooting:

Hi. I am trying to get SharpCap working with a Sony a6000. I've installed the ASCOM driver, but when I open SharpCap it immediately begins snapping pictures with whatever settings were set in the Sony Remote app (i.e. iso & shutter speed). It saves ARW and jpg files just the way the Remote app does, as well as clicking the shutter. I am trying to record ser videos in SharpCap for more convenient lunar stacking. Is this supported for the a6000? Or is that part of "Live View", which I know is not supported for the a6000. Is there a way to get this working?

Thank you!

Hi,

the Sony ASCOM driver only supports capturing still images (or at least it only works that way in SharpCap - in theory there is a standard now for ASCOM video cameras, but SharpCap doesn't support it yet, and I suspect that the Sony ASCOM driver doesn't either)..

cheers,

That is correct Robin.
I don't know if the Sony API allows direct streaming of video - the "Live" view shown in the Sony Remote app is just a series of JPEG images (1024x960 pixels) that are displayed quickly enough by that app to simulate video-like behavior.
ASCOM being ASCOM, it's not really up to the task of running at anywhere near that kind of speed.
The Sony driver does support reading these JPEG liveview images, but it requires the cooperation of the application as the ASCOM Camera standard has no knowledge of these things (on my machine it can get around 4fps "LiveView" performance thru to APT).

Just in case anyone is interested, in the next few days I'll be releasing a new version of the driver that can control the exposure time using the camera settings.
This means if you want to take a long exposure it'll use BULB mode, but when you want to take flats or bias images it will be able to wind the exposure time on the camera down to the 1/4000" or 1/8000" setting so you get consistent exposure length's.

I've been able to test this on NINA (and shortly APT) but I'm not a big Sharpcap user, so if anyone wants to get in early hit me up via retrodotkiwi<at>gmail<dot>com
