Camera ZWO ASI120MM-S USB3.0

The ASI120MM-S camera is a small guide camera, well suited to short focal lengths (due to the small pixels, and the size of the sensor). It is the ideal solution for economical guidance. Note that it works in USB3, ie it is faster than the ASI120MINI (the latter is in USB2).
To be used on all the spectrographs of the Shelyak game, you will need to complete with the purchase of 2 rings:
– a M42 (male) to C-mount (female) adapter ring (Ref. BA0034)
Check that this ring is not already included in your camera’s box.
– A 5mm-thick ring(Ref. BA0036) to bring the backfocus to 17.5mm.
