Re: Software advice for stacking photos

You don't need but one reference if the scope is tracking in RA adjusting just
one axis, as occurs with a true equatorial mount. Then the sky dos not rotate,
and therefore one point is enough of a track.

If you're doing non-trailed wide angles, then you're tracking on one axis for
the sky, and not two as occurs with most GOTO scopes operating in alt-azimuth
mode, and you can use Registax.
