Absolutely – just select the SharpCap Pro features that you are interested in and start using them. For most SharpCap Pro features, the only restriction is that you cannot save any images while you are trying out features without a license. For Polar Alignment, you cannot access the final adjustment stage in trial mode.
When you decide to try out a SharpCap Pro feature, SharpCap will let you know what restrictions will be applied and give you the chance to continue with the trial or cancel if you want. To get back to normal (no restrictions) just close and re-open SharpCap.
