  1. thanks for the link, I was using the one from your blog page , so will update. I think I will make up another focuser for my 127mm now such a cool project
  2. ah that's great. I the sketch I have is R5 I think dated 13 April 2014. I'll see if there is a later one
  3. hi is there any way to get the ascom driver to start at say position 1000 rather than 1 as it basically means that one can only focus one direction, at lest in focusmax, unless the ascom chooser is opened and the position entered manually. With the 200mm lens I normally keep it at last focus position (to do flats etc) and don't want to wind the focus in one direction fully. the focuser is now working a treat with an external 5v driving the stepper, no more stuttering or slipping
  4. hi I decided to just get the adfruit motor shield as I didn't want to mess around with adapting the easy stepper board too much. got the project finished. It works a treat on the bench although I had a bit of an issue on the mount as I think the USB hum system is not sufficient to drive the stepper properly. It just does not seem to have enough torque to drive the belt to the Canon 200mm lens. I think I will add a 12v supply to the motor shield board. It's a excellent project and will really help in the critical focusing of this lens
  5. excellent project. I have just got a 200mm lens and I was going to try and build this focuser. Parts ordered to try the drive belt approach. I already have an arduino. I ordered an easy driver board so hopefully I will be able to use this with the arduino.

  9. wondering if it's worth taking the scope out tonight

  10. totally agree. I was thinking abot getting a CCD but the infrequent use makes it hard to justify.
