This adapter has a 2" filter male thread (M48x0.75) as well as a T / T2 female thread (M42x0.75) on one side. It has an SCT female thread (2"x24TPI) on the other side. So this adapter can be used as (i) an SCT female to T / T2 female adapter, or as (ii) an SCT female to M48 male adapter.
Important note: Since this is a slim adapter with a very short SCT female thread, this item cannot be used directly on the male SCT threads on the rear of telescopes or on SCT focal reducers since these typically have 2 or 3mm of unthreaded barrel before the threads start. With these items, this adapter's SCT female thread will simply not catch on.
Specifications:
- Total thickness = 5.5mm (0.22")
- Length of SCT female thread = 1.5mm (0.06")
- Length of M48 male thread = 1.7mm (0.07")
- Length of T / T2 female thread = 2.5mm (0.1")
- Maximum outside diameter = 55mm (2.17")
- Made of black anodized aluminum.
