A No-Harm GoTo Home Made Oak Dob
This is an example of what can be done to a telescope without harming the mount in any way. The customer that owns this scope shipped me just the mount and tube cradle. I did the rest of the conversion for him. No harm was done to the mount at all. He can undo all of the conversion and use it on another scope if he wishes, with some modification. The manual movement of the scope is retained.
You see the three wooden blocks on the side of the rockerbox ? They are the clamps that hold the geartrain plate to the side of the scope. I could easily have made them metal, but chose to keep the wood look. They bolt into places where there was already a screw. I just took his out and used a longer one in it's place.
The 'tin can' in the back is a scope of mine.
Remember, there is no harm done to this scope. Those clamps come off easily and don't mar the finish on the scope.
- Unlike other GoTo systems, all of our systems are GoTo telescope controls for a lifetime. The circuitry, motors, computer, cables, software and (usually) the gearing, can be used on other mounts (Dobs or GEMS) with a little modification to the new mounting.
- It does NOT use encoders, none are required or even recommended.
- There is no Field de-rotator included in any system but the system is quite capable of using one for astrophotography.
- Stepper motors that are quiet enough to talk over in a normal tone of voice when tracking and nearly silent when slewing.
- Time tested software and hardware.
- No permanent modifications to the telescope mount itself. Almost all of our systems are removable should you upgrade to a larger mounting.
- A small 17 amp hour gel cell battery is good for one night of observing.
- Resolution is at .225 arc seconds for this mount. Better resolution is available on request.
- Laptop can be an old 486 and can be included with your order.
- Software is included and pre-configured.
- Telephone and e-mail support is available for free.

- Laptops and the circuitry can usually be powered from the same battery. There is no need typically, for a power outlet.
- LX-200 interface for control with other computer programs, standard.
- 40 microsteps per full step of the motors. Typical number of microsteps with the gearing is 5, 760,000.

- Realtime display of coordinates.
- Built in observing log is standard.
- Wireless mouse operation available.
Here is a picture of a laptop and the pcb together. We attach the two with long pieces of industrial strength velcro. The laptop just sits on top of the pcb. BOTH can be made to run off of one single battery at your request. I have done this with quite a few laptops and all have worked perfectly running off of 12 volts.
