Although the CoStar is primarily intended as a high performance guider, it makes an excellent electronic finder and planetary imaging camera!
- Imager type: Aptina MT9M001 mono cmos chip with low dark current and anti-blooming.

The top image is a 5 second expore taken with the CoStar with a F5 80mm telescope. The bottom is the same scope view but with the Lodestar instead. While the Lodestar is more sensitive, the CoStar is still an excellent guider.
