Preview the next major release of PlaneWave Interface

The upcoming PWI 4.1 release will support a wider array of hardware. This preview version includes support for Series 5 Focuser and Rotator hardware.

This version supports both Maxim DL and ASCOM-based cameras when building pointing models and performing focus runs.

If you have a custom LMount.cfg that was generated for an older version of PWI4, it will automatically be migrated to the new configuration scheme for this version.

If you use a PW1000 and currently use a PW1000_custom.cfg config file, these settings are not yet automatically migrated. This will be added in a future release.
