How do I a make a #506 cable for the AutoStar #494?
A. The ETX-60AT and ETX-70AT with the #494 AutoStar requires the #506 cable. This cable includes some special electronics that are needed (unlike the #495 and #497 AutoStars). The specifications of these special electronics are not publicly available so you can’t make a cable that will work with the #494. You have to purchase one from Meade.
