- This item is no longer available.
Our camera adapter allows you to attach your SLR (35 mm or digital) camera to any focuser that accepts 2" slip-in accessories. It is machined of aluminum, black-anodized and the inside is painted flat black. The I.D. of the opening where your camera attaches is 1.52" (38.6 mm) (some other camera adapters have a thick wall, which reduces the opening to your camera). The camera adapter is threaded for the popular 48 mm filters.
Note the tapered 2" barrel. When used with our brass locking ring (or any locking ring clamp), this unique barrel will seat your valuable camera squarely and solidly into place. Even a single thumbscrew interface will be improved. '
Purchase the adapter with or without a t-ring. Please specify the T-ring that you wish to use.
