The AG-131M CoolAir is a USB2.0 fan-cooled camera that offers exceptional performance and versatility easily outperforming cameras costing considerably more.

This guide camera uses a 4.9 x 3.7mm CCD (1/3" format) and will slide into a 1.25" focusing assembly. It may also be used with a 'CS' mount camera lens. The weight is less than 100 grams.

As an upgrade to the original Lodestar autoguider, the Lodestar X2 has the Sony ICX829 Exview chip with improved sensitivity and quantum efficiency for a result if doubled sensitivity over the original Lodestar autoguider

The 1/3 inch Aptina MT9M034 sensor is a 1.2 mp CCD chip. The pixel size is 3.75um which can reach a maximum full resolution frame rate of 30 fps.

The Orion StarShoot AutoGuider Pro Mono is a great design for both autoguiding and a solar system camera. With its high sensitivity and QE of 74%, details will become more apparent in exposures.

SBIG has developed a new spectrograph specifically for our ST-i camera.

The Exview Autoguider is a larger-format development of the older SXV Autoguider. It uses an ICX429 'Exview' CCD in binned 2x2 mode to give excellent sensitivity and rapid readout.

Although the CoStar is primarily intended as a high performance guider, it makes an excellent electronic finder and planetary imaging camera!

Employing the use of both a dedicated autoguider and guide scope is arguably the best way to optimize the accuracy of any astrophotography pursuit.

The Opticstar AG-131C COOLAIR auto-guiding system includes everything you need to auto-guide any telescope with an ST-4 compatible port (this includes the vast majority of telescope mounts).

Autoguiding has revolutionized the capture of deep-sky images by mechanizing the tedious and tiring method of "manually" guiding an exposure, which involved staring endlessly into an illuminated reticle eyepiece while tweaking your mount's electronic drive controls by hand to keep the stars pinpoint sharp.

SBIG began with the ST-4 autoguider nearly 20 years ago. This venerable stand-alone unit is still used by many for digital astrophotography.

The SBIG STI planetary and guiding camera is a full color autoguider camera capable of capturing high resolution images of the planets and Moon. The size of a typical 1.25" eyepiece, the ST-I is a compact imaging solution with a mechnical shutter for automatic dark frames making this a powerful and versatile camera.
