About SharpCap Beta

Be aware: Beta versions of SharpCap have had less testing than usual and may contain unfinished or experimental features.

If you choose to use a beta version of SharpCap, please test the cameras and functionality you intend to use before an observing session to avoid frustration and lost observing time. You can install a beta version of SharpCap without having to uninstall the previous release version, so it's easy to have both on the same machine and switch between them.

All beta versions have a built in time limit - they will only work up until a particular date (usually they have a life of a month or two). If your beta version runs out, check back at this page for an updated beta (or check the main downloads page for a new release). 

You can use most SharpCap Pro features that are new in this version during the beta period without a license.

NOTE: If your camera is not detected, you may need to install the SharpCap Pre-Requisites Installer. You only need to do this once, not for every new beta build.
