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.

New Project - FocusMac

Recently I started building myself a motorized focuser based on the ideas generated by the SGL Observatory Automation group. I'm part-way through the build, although I still have the circuitry attached to a breadboard and I am writing my own firmware to drive the focuser. I could have just used the SGL firmware, but as a developer, I wanted to have the fun of doing this bit myself. In the process, I think I will be able to implement some improvements, such as allowing the focuser motor to move while the firmware remains responsive to the serial command protocol.

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.
