Lodestar X2  (stand-alone) Autoguider (Colour)

SKU: 110-0012 Categories: ,

Description

The Lodestar C is a very compact imager / guider which is powered and operated via a single USB2.0 computer connection. It also provides an opto-isolated output connection for direct control of most mounts, via their ‘Autoguider’ sockets. This output is compatible with the ‘ST4’ style of RJ12 connection and supplies 4 ‘pull down’ direction lines and a common return. Alternatively, you may send the mount control signals via a serial connection from the guider control computer.

The Lodestar utilises a very sensitive Sony ‘ExView’ CCD (the ICX829AK) with an array of 752 x 580 pixels in a ‘half-inch’ format. Although the chip is not cooled, it has a very low dark signal and very little readout noise, so it can be used to guide on faint stars that are beyond the reach of webcams and CMOS chip based guide cameras.
