PHD Guiding (Download Windows, Download OS X)

1.8.3 (4/2/2008) - Pre-release
- Support added for SXV / SXVF cams including the Lodestar. Both Mac and Windows.
- Setpoint.exe bug fixed -- Most DLLs set to delay-load. Users of the SAC4-2 will still have issues if running setpoint.exe. This is a camera driver issue, not a PHD issue.

Craterlet OS X (0.2) Download
Craterlet for OS X is designed to give Mac users simple capture application for DCAM-compliant firewire cameras such as those from The Imaging Source (sorry, the iSight is not DCAM-compliant). It's main application here will be to let you stream planetary or lunar images to disk. However, given the long-exposure options present in these cameras, other applications (e.g. DSO work) will certainly exist.

Currently, this is an early release. I have tested it with a monochrome camera (DMK 31AF03.AS) and with monochrome and color Unibrain Fire-i cameras. Images can be streamed to disk in BMP, JPEG, PNG, or TIFF formats. On color cameras, it will stream color images, currently using the camera's onboard debayers even if pure RAW modes exist. I welcome bug reports and any other assistance users can provide in testing. Let me know what camera you are using, what modes show up (note, you can only selet a mode while Preview is not active), and how it behaves.

Craterlet OS X is freeware. OS X 10.4 is required (some chance it will work with 10.3.9).
