I submitted a ticket to Atik support last week, but yet to receive any reply.
It looks there is no support from Atik recently for this buggy driver. Support service was quite good a few years ago.
I updated the core software and driver to 5.0.0.4 (was from 4.2.2.9), on my Atik One, but it doesn't work.
In SGP (via ASCOM):
1. After I connect the camera, the filter wheel is not found
2. Symptom similar to #1, when the filter wheel is connected, the camera can't
3. It looks the camera and filter cannot connect simultaneously with the new driver
4. The filter wheel movement is much more noisy, than the 4.2.2.9 driver
5. Performance wise, it is also inferior, it takes much longer to find the camera by the driver, also on connecting. Same as for the filter wheel.
I am not sure, whether there is any advantage in using the DLL than under Windows services, with the issues found.
