Antares' new f/6.3 focal reducer provides a faster f/6.3 system for imaging or visual use when used with an f/10 SCT. This filter threads on to the rear cell of your Celestron or Meade SCT telescope. The female end attaches to the rear cell of the telescope. All additional accessories mount onto the exterior/male threads. The reducer features fully coated optics in an anodized aluminum filter ring with an ergonomic rubber grip. Customers have reported that this product is at least as good as, and probably better than, the Meade and Celestron f/6.3 focal reducers sold for a lot more. Focal length = 220mm. Made in Canada.
