Customer Note: For 203mm (8") f/4.9 and 254mm (10") f/4.7 Orion reflectors, a #5122 eyepiece adapter is needed to reach focus. For attachment of a camera body for prime-focus photography, a #5117 T-thread camera adapter is required (sold separately).

*Note: The 2" Crayford-Style Focuser is not a drop-in replacement for the Orion SkyQuest XT8 Classic Dobsonian or Orion reflectors smaller than 8" aperture without modification of the telescope. Orion SkyQuest Classic Dobsonians purchased prior to 2002 also require modification in order to use the 2" Crayford focuser. Regardless of the telescope you plan to attach this focuser to, it would be a good idea to take a look at the Orion 2" Crayford-Style Focuser Instruction Manual before you buy, just to make sure it will fit and focus correctly.
