Which driver for EFW3 and TheSkyX?
« on: February 29, 2020, 08:10:32 pm »
I downloaded the latest version of the core drivers (, and I still don't see a choice for EFW3.  I tried the EFW2 choice but all it does is hang TheSkyX when I try to connect.

This core version does work with the native driver for the camera now though, which is nice. 

Am I just stuck with using the Ascom driver for the FW?

Hello Jamie,

Did you email our support with this issue? If not, the ASCOM driver is the only driver supported by us now, the native driver was written by Software Bisque but should work. When selecting the EFW3 in ASCOM are you seeing the attached screenshot? The EFW2 and 3 are are selected with the same driver EFW2/3.

Hope this helps.
Best regards

HI - you should find that this will work. However, there is a bug in the Ascom camera server used to connect to the FW which causes a memory leak. After a while, the driver will stop responding.

I had to revert to an earlier daily build (12439) and install the legacy Atik software to get a reliable connection to the FW.

Hope this helps,
