Met up with Tom How for the first time in quite a while and he brought along the stepper motor/Arduino drive unit for auto-focusing the Canon 200mm lens. Focusmax talks to the unit (and to Maxim DL) and it all looks the business. Just need to have the top plate off the mini-WASP AGAIN to replace the JMI electric focuser with this stepper and I should be in business. Yet another quality astronomical product from the Tom How factory 🙂
