Hi Everyone,

It’s been a while since I’ve shown any of my work. Been pretty busy. Like a lot of you out there, woodworking started as a hobby and then turned into a full time job. A while back I decided to get into Astronomy ‘as a hobby’
I bought a ZHUMELL Dobsonian 12” telescope and built an observation deck outside my shop.

You know how woodworkers are, we like to solve problems. I was having difficulty steering my telescope so I began to experiment with the idea of a slow motion control for the DOBSONIAN. After several proto-types I came up with
what I am now marketing as ZLOMOTION. You can check it out at

Merry Christmas Everyone!

Interesting. So does it use hydraulic pistons to slow the altitude/azimuth movement?

Hi Brian,

The base tension knob is loosened and the belt tension is all that is needed,
and can be adjusted via the aluminum plate. The Altitude device works by gravity.
The telescope is adjusted to be top heavy and the bearings that are on the scope are loosened.
If you haven’t been to the website, >, go there and checkout the YouTube videos.
Thanks for your interest. Do you have a scope?

I have a 10” Dob on a homemade mount. Nothing fancy, but it gets the job done.

Nice work on that scope. You can’t see anything where I live now but years back in the country had a simple 6” refractor. It was fun but even with a 6” I couldn’t track well enough by hand. The moon was impressive though.
