Description

Build your own GoTo Astrophotography mount, fully open-source! 

 

The OpenAstroExplorer is a compact and portable equatorial mount designed for light to midrange astrophotography setups.

 

It features a fully belt driven RA axis, resulting in very low backlash and PE, using the same two-stage 9:1 gearbox as OAM. It also includes a magnetically detachable RA ring, a compact worm gear driven DEC axis, and a foldable ALTAZ mechanism, optimized for easy transportation and quick setup in the field. Despite its focus on portability, the OAE offers precise tracking and guiding with a good payload capacity.

 

A built-in Auto Polar Alignment (AutoPA) mechanism simplifies setup, making the mount user-friendly for both experienced and new astrophotographers.

 

 

You can find all the relevant guides, BOM and print instructions on our wiki:

The print files here on Makerworld include all the main parts but you will have to print the appropriate Counterweight and Tripod adapter from the “other” folder.
