The HomeBrew Gen4 (HBG4) Accessory for Celestron Mounts


Pardon the lack of explanation here -- to be updated some day!

In short, the HBG4 is a more powerful version of the venerable HomeBrew Gen3 (HBG3), with all of the same capabilities (and more!) as well as a faster processor, more RAM, and more FLASH memory. Over time, firmware improvements will begin to make more and more use of the expanded capabilities.

The ongoing HBG4 development is discussed here: Cloudy Nights HBG4 Discussion Thread.

In the USA, PCBs, kits, and possibly assembled/tested units are available from: hbg3pcb@gmail.com
