[OneCosmos (Chris)]

Meade DSI pro monochrome CCD (Sony ExView CCD 510x492 pixels, 16-bit, USB2). This has been modified to remove the rather useless filter slide, which was prone to light leaks and dust, and replace it with a T-2 thread (M42 x 0.75) adapter that accepts a standard 1.25" or 2" nosepiece or a filter wheel. A 1.25" nosepiece is supplied with the CCD. Makes an excellent autoguider, and still a capable imaging CCD.

Comes with original driver/software CCD with Meade Envisage, but no box or USB cable. Works perfectly with PHD guiding.

Looking for $200.
