But on another scope, I have just fitted a new device that is marketed as an electronic eyepiece and a 3 Meg resolution and it seems to be promising. It is a web cam style of device, like the ToUCam and therefore will work with programs like MetaGuide. But I have yet to give it a bit of sky. The moon is still too bright but I'm hoping that there will be enough time before it rises to give it a proper test. The device is made by a Chinese (surprise, surprise) call Jicheng or some such and has a serial number MD300.
I have had PHD recognise it as well and the picture is sharp and well-defined so I'm fairly confident it will work pretty well.

Just did a quick google on the MD300, it's actually made by a company called
Zhejiang Jincheng Digital Photo Express Chain Co., Ltd.
The specs are: MD300 Electronic eyepiece
Specification: Type: 1/2" CMOS Active Pixel : 2048X1536 Resolution : QXGA 2048X1536 XGA 1024X768 DV 1024X510 HF 1024X190 Pixel size: 3.18um X 3.18um Frame Rate: 2048x1536 7.5fps 1024x768 20fps 1024x510 30fps 1024x190 78fps Exposure: Manual/Auto Exposure SNR: 46dB Out port: USB2.0
The attached pic is a bit confusing, as it shows a front and a back view. The front view shows what appears to be a 1.25 eyepiece tube.
Sensor is CMOS. May be good enough for guiding? Wonder what the price is?
