With an enhanced aluminum coating giving 96% reflectivity, this diagonal has much to offer. Attach this diagonal to your telescope via a 2" threaded barrel (threaded for 49mm filters, and not for conventional 48mm astronomy filters). This diagonal allows use of the flip mirror to change between its standard 90 degree 1.25" eyepiece or the multi purpose eyepiece/photography port straight through, yielding 100% transmission. This port not only fits many photo adapters but also unthreads to a standard 42mm T-Ring thread. Use with Item 37292, a 2" adapter to change the port on your flip mirror.
