LodeStar Guider Camera

As per my review of the EQ6 Pier from AstroShop I have been selling some of my equipment to start stepping up in the capabilities of the equipment I use, this included my Orion Awesome Auto Guider kit and GStar EX mono camera. I was simply carrying too much load on my mount and was also having issues balancing my set up with three scopes attached.

In replacement of the Orion Awesome Auto Guider and GStar was the Starlight Express LodeStar Guider. This camera is very similar to the GStar in sensitivity but a lot smaller and is compatible with many guiding software platforms such as PHD. This allowed me to remove one of the scopes from my mount and lighten the load a little.

It came packaged very well in a blue plastic case holding the Driver/Software CD, USB Cables, ST4 Cable and naturally the camera.
