There are several ways to build a telescope mount drive including manufacturing your own precision worm gear check out this DIY build from the Curdridge Observatory but Ive opted to use a modified barn-door drive. The Barn-door mount gets its name from the two plates of plywood with a hinge connecting them like a barn-door. The double arm design was first described in an article by Dave Trott published in the February 1988 issue of Sky Telescope magazine.

A barn door is a specialized type of equatorial mount. At its heart the motorized version is essentially the same as the motorized barn-door tracker. I dont have a dobsonian but a small tabletop reflector Zhumell Z114 so the idea of building an EQ platform looks appealing although challenging.

I remedied this simply by filing down a bit of the motors. We see it pictured above installed on an old Celestron equatorial wedge which has adjustments for altitude and azimuth. The mount shown here employs a Type 4 double arm design.

In addition if you make a wider barn door you could mount multiple cameras on it for meteor showers. As a result the motor and curved bolt rubbed against each other which is obviously not a good thing. Each drive has two long arms and a lead screw to push the arms away from each other.

The motor opens the door very slowly to match the skys rotation. Known generically as a barn-door tracking platform its easy to make and works well for camera-and-lens astrophotography. To attach the motor off to the side where it is on my barn-door tracker I chose to mount mine in-line for a more-compact assembly.

You mount your camera on the door then aim the hinge straight at the North Star Polaris. Commercially available mount options have a starting price of several hundred pounds and range up to.

The telescope is usually fitted entirely inside the fork although there are exceptions such as the Mt. A gear head on the tripod with altitude azimuth adjustments can make polar alignment much easier. Serious astronomical imaging requires an equatorial mount for the camera telescope which tracks the rotation of the earth for anywhere between 5 minutes and several hours.

After reading that thread I see now. The mount can also be placed on a heavy-duty photo tripod. There was something about this telescope on top of.

January 12 2019 at 1043 pm Id have to do the math though seems like the longer arm radius systems. I built the tracker shown here based on one recently made by Ohio telescope maker Ed Jones and on a platform built by Sky Telescope s Dennis di Cicco in the mid-1980s. A summary about the DIY german equatorial telescope mount I have made and used for astrophotography in my observatory.
