Altair Atmospheric Dispersion Corrector for planetary and lunar imaging or observing. 

The ADC corrects for atmospheric dispersion (rainbow effect) producing sharper images of object closer to the horizon.

Particularly useful on Mars, Saturn, Jupiter and the moon at about 20-40 degrees altitude which.

The prisms are high quality K9 glass with broadband multicoatings and a prism angle of 2.5° which gives a maximum deviation angle of 5°, which is ideal for the UK, Europe and North America.

The rear side has 1.25" pushfit adapter with 3x thumbscrews and internal compression ring to protect your Altair or other CMOS cameras and eyepieces. The pushfit adapter can be unscrewed to reveal a T-Thread for direct camera connection. The nosepiece is threaded for filters.

This is a high quality accessory as the images by Mr Neil Phillipson of the Langrenus area on the moon will attest (click thumbnails for full resolution).

The unit has a rotating lockable scale, so you can record your optimum settings.
