Here's a post that may be of interest to the DIY ATM makers. It's a motor focus for my Celestron SE6. I made it as I spend most of my observing time on my PC doing Electronically Assisted Astronomy (EAA), and found it hard to manually focus my telescope while looking at my PC screen. The setup consists of a dual control box, a breakout box and the motorfocus unit. The motorfocus unit is a modified MG90S micro servo with a machined nylon sleeve that slips over the rubber focusing Knob on the SE6. The Control box Has 2 pulse width modulator speed controls, 2 DPDT switches 2 push button switches and 3 LED's the top switch is for a LED light. The control box is connected to the breakout box using 5 pin din plugs and a MIDI cable. The unit is powered by a spare USB port on my PC.All parts were purchased on Ebay amd the total cost was about $25AUD.
