Orion drive in action, the battery pack was corroded so I replaced the power source with a USB power bank.

Re: WTS: Celestron Byers fork + extra Byers gear

Note that I 3D-printed two spacers (the white strips) to increase the spacing between the two arms to fit the Mewlon (this particular fork came off a C-8).

WTS: Celestron Byers fork + extra Byers gear

I was planning on making a goto Alt-Az mount for my Mewlon but it’s been 3 years and I haven’t been able to get to this. All metal 1980’s Celestron fork mount for C-8/9/11 with legendary Byers gear on RA only. Extra Byers gear to motorise the DEC (these only came with a tangent arm on DEC). No elect...
