Smart Telescope Planner
Version 23.0 (1) on Mac, iPhone, iPad, and Windows
Version 23.0 (1) is the same release on Mac, iPhone, iPad, and Windows, prepared for release. It is a free download with a 20-day free trial. Full Access is a one-time purchase: $12.99 on Mac and Windows, $9.99 on iPhone and iPad (US prices). If you bought the planner before it became free, you keep Full Access with no additional purchase. Bought it before it became free and having trouble with access? Email support@bigskyastro.com. Build Plan places every selected target across its Clear Sky, so the times overlap. Balance Plan gives nearly equal time. Use Priority gives more time to rank 1. The store links still open the versions on sale today until this release is approved.
