Notes about Sharpcap - FearL0rd/ASCOM.DSLR GitHub Wiki

We strongly recommend using Sharcap 4.0 or higher. 4.0 is currently available as a Beta version.

If using with versions of Sharpcap below 3.3, when connecting to the camera, Sharpcap will immediately start taking pictures. This is normal as Sharpcap was originally designed for cameras without a shutter. This is fixed with the Sharpcap 4.0 beta, and should be in the 4.0 full release.
