This little combo makes for a superb 'guidescope'. It is a 100mm lens, f2.8 designed to attach to an SBIG STi guider.
Of course, CCD based guiders are no longer available and the STi has a shutter! So dark subtracted exposures are easily accomplished.
I am happy to sell this as a complete kit and both items are in perfect condition.
The STi used to be $595USD new and the lens $349USD new, a total of $944USD or about $1280AUD or so. Grab this pair now for $700 (was $850AUD, then $775) shipping on me.
regards
Martin
