This 1.25" SCT Visual Back # E-15 by Blue Fireball allows you to attach 1.25" eyepieces and accessories to most SCT telescopes that have a standard male SCT thread (2" x 24 TPI). Some larger Maksutov-Cassegrain telescopes feature a larger 2" SCT thread, and this visual back can be used with those telescopes too. Note that this item is not meant for use with smaller Mak telescopes that might have a smaller 44.5mm Mak thread, a smaller 1.375" NX4/ETX thread, or with other telescopes or accessories that feature an M42 T/ T2 thread.
This high quality adapter has an SCT female thread (2" x 24 TPI) on one end and a 1.25" eyepiece barrel on the other end. The eyepiece barrel features a brass compression ring.
Please note that this new version now features two thumbscrews, even though the item is threaded for three screws. Since we cannot predict the orientation of the thumbscrews when this item is fully threaded on to your telescope or accessory, we added the extra hole so that you can pick which two you want to use. The item is not missing the third screw.
Specifications:
- Total length = 40mm (1.57")
- Maximum diameter = 55mm (2.17")
- Length of female SCT thread = 6mm (0.24")
- Female thread specification = SCT thread, 2" x 24 TPI female
- Made of black anodized aluminum.
