Good clean condition.
This adapter allows the attachment of anything with a 2" tube (such as a standard 2" diagonal) to be attached directly to your Meade SCT without using the microfocuser. By doing so, you significantly shorten the optical train, improving backfocus while permitting accessories to clear the scope base - allowing telescope use at 90° declination. As with the EyeOpener, the adapter retains a full and unrestricted 2" diameter optical path.
The 2" Tube Adapter piggybacks onto the EyeOpener II, which in turn threads onto the 3-1/4" thread on the backplate of the Meade 10", 12" and 14" SCTs.
The adapter is fabricated from 6061T6 aluminum and black anodized. The attachment screws are stainless steel, and are long enough to allow clear finger access without bumping your fingers into the scope backplate or the attached device. A brass compression ring is used to prevent marring the inserted 2" tube while griping it tightly.
The total height of the adapter above the scope's backplate is only 1-1/2 inches (38 mm). By comparison, with the standard configuration, the nominal height from the scope's backplate to the back of the microfocuser is 3-1/8 inches.
