Welcome to EQMac

This site is the home for the EQMac software, designed to control Skywatcher and certain Atlas equatorial mounts directly from your Mac. Here you will find some basic guides on configuring and using the software, as well as downloads.

If you have any requests, questions, or comments about the software, please use the contact form in the menu, or you can find me on Stargazers' Lounge as OzDave.

EQMac v1.1.0 Beta Release

This update adds a couple of exciting new features. Firstly, I have finally finished enough of the Gamepad module that it can be usefully released. This will enable you to plug in a USB gamepad and configure functions for each of the buttons and joysticks. Once calibrated, it will make the task of slewing the mount while looking through the eyepiece much easier! The major new feature though, is the provision of an LX200 protocol emulation over an IP connection.

EQMac v1.0.3 Released!

Some people have reported that EQMac sometimes starts up and crashes or just doesn't seem to get past the yellow LED stage when communicating with the mount. I have had a look into things and found a few places in the code that could have been causing these types of issues. This update therefore provides fixes for those issues and should hopefully result in a more reliable startup process and also initial communication with the mount. I would be grateful if people trying this release could let me know whether it improves anything.

EQMac v1.0.1 Released!

I've just released v1.0.1 to fix the issue with Parking and Polarscope alignment not working correctly when upgrading from v0.0.6 (or earlier).

Once you have started using v1.0.0 or higher, please do not use earlier versions of the software again otherwise you may experience problems with the Parking and Polarscope features causing your mount to slew in an unpredictable manner.

Bug Alert v1.0.0!

WARNING

v1.0.0 contains a relatively serious issue affecting Parking and the Polarscope Alignment features. Due to a change in the way certain coordinates are stored between v0.0.6 and v1.0.0, Polarscope calibration and Parking/Unparking may not work correctly and may cause your mount to slew in an unpredictable manner. This will only cause a problem if your mount is parked using v0.0.6 and you try to unpark with v1.0.0, or you try to use the polar alignment feature without recalibrating.
