Hi Andy,
It is perhaps also interesting for spectroscopy. I see from the specs that the sensor is larger than the one in the SeeStar 30 which means that unlike the Seestars it could potentially be used directly with a Star Analyser recording the full spectrum in one shot (not including the zero order, though that plus the blue end of the spectrum could be captures separately.) The equatorial mode would also avoid the problem of the spectrum fanning out due to field rotation which is seen with the SeeStar. The tiny 2 micron pixels means the image is probably well over sampled which should be good for avoiding artifacts with the colour sensor.
Cheers
Robin
