Autofocuser recommendations wanted for a Startravel 102


Recommended Posts

When I had a Startravel 120 I used the combination of these two:

I think the ST102 has the same focuser, but you need to be sure that the knob on the focuser is removable (mine was, glued but I managed to clamp axel and use a pair of adjustable wide pliers. See note in the FLO product page). If you can't remove the knob, then the focuser can't be attached.

Another thing to note, is that this is a DC motor, and not a Stepper motor. This means that when you move steps in one direction the same amount of steps in the other direction may not be the same. Some people have compensated for this by attaching rubber bands between the imaging train and the OTA, to make the steps more equal.

I could not find a stepper motor which could be attached to a Star Travel, and have since upgraded to an Esprit.

I think another option for you would be to replace the stock focuser on the ST to one that would accept a stepper motor, such as the ZWO EAF, or the Sesto Senso 2 (which is what I now use on the Esprit).
