Atik OAG


As a complement to the EFW2 filter wheel, we developed an Off-Axis Guider. The Atik OAG features a moving prism which allows selecting the best quality stars of your corrected field of view, while maintaining the possibility of using from small VGA sensors up to 35mm multi megapixel full frame beasts.

RRP  203€ / $244 (excl. tax)

The Atik OAG features an extremely smooth and precise fine focus system, with extension rings of 3 different lengths, so that different types of cameras reach focus with different types of autoguiders.

It interfaces perfectly with the EFW2.2, meaning that no spacing exists between both units, keeping total backfocus requirements low. The OAG can also be used without the EFW2.2  by using an adapter.
