The OpenAstroGuider is a printable 50/183mm guide scope with a integrated IMX290 sensor that can be mounted to OAT directly, or be adapted to mini-Vixen clamps.
It can be used for Guiding OAT, OAM or any other mount with ASCOM support.
It does not support an ST4 interface, so you can not use it with star trackers like the Star Adventurer without a special USB-to-ST4 adapter.
There are currently two designs you can choose from: OAG v3, and Andre's Improved Guider.
OAG's revison history is v1 -> improved -> v2 -> v3.
¶ OpenAstroGuider v3.1
This is the official guider design. You can find the CAD and STL on GitHub
Assembly Instructions are here.
Compared to v2, Version 3 of the OpenAstroGuider has the following improvements:
- Sturdier build
- Sturdier holders
- Better focuser
- Lens cap can now simply be clipped on
- Light baffles against internal reflections
- Strain relief for IMX USB cable
- (optional) Build in dew heater powered directly from USB power
¶ Andre's Improved Guider
The improvements of this Design were mostly over v1 of the official design. It is fairly similar to v2 and slightly simpler to build and print than v3.
