QHY5L-II has 74% high QE, 4 electron readout noise and 3.75um small pixels. This camera is idea for the short focal guide scope. miniGuideScope is a f=130mm Diameter=30mm ultra small telescope with F4.3 ratio. It has no complex focal adjust system. Just rotate the front part focuser it can get fine focal adjustment. There is a locker to fix the focuser position.When it get focus you can lock it and no need focus again in future.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv style=\"margin-top: 0px; margin-bottom: 0px;
