Description

Testing in live conditions a homemade motorized Samy focuser.

Prototype version for now. A 5V stepper motor is screwed on a rig which stands between the Novoflex tripod collar and the Skywatcher L-bracket.

The motor is controlled by an Arduino. Commands are sent from the PC.

Very few vibrations and shaking ! This is very usefull to focus the pair [Samy + ASI camera].

Next step is to replace the Arduino board by a smaller board and to add controls (buttons or remote control from the smartphone).

Another option is to put an ASCOM driver on the board and try to do auto focusing :-)

About the Pleiades image : not enough integration time ! :-)

Last revision : final version with Wemos D1 board. Rotation is controlled from a web browser (from smartphone, tablet or computer).
