Vixen Flip Mirror Diagonal for 2" Focusers
Are you ready for a whole new concept in viewing possibility? The Vixen Flip Mirror Diagonal attaches to your telescope via a 2” threaded barrel that accepts 49mm filters. This diagonal has an enhanced aluminum coating for 96% transmission, and incorporates the use of a flip mirror to change between its standard 90º 1.25” eyepiece port and the multi-purpose, straight through eyepiece/photography port.
The straight-through port on the Vixen Flip Mirror Diagonal not only accepts many photo adapters but also unthreads to reveal a standard 42mm T-Ring thread.

Product QuestionsThe straight through photo part is removable revealing 42m threads for T-Ring for cameras, does this include DSLR's like Canon and is this unit compatible with Celestron's f/6.3 reducer/corrector in the imaging train lline up?Question by: Duane on Oct 19, 2015 11:31:00 AMYou can use this M42 adapter to connect a T ring and DSLR, but this combo is then too long to use with an f/6.3 focal reducer. The f/6.3 reducer has a nominal back focus of 105mm, the DSLR and T ring take up 55mm, and the flip mirror body plus nosepiece with minimal length SCT-2" adapter (OS-ASCT2), take up more than 100mm. This flip mirror will have to be used at the native focal ratio of the scope you are attaching it to.Answer by: Chris Hendren (Admin) on Oct 20, 2015 12:19:00 PMDear,
can I take just the central cube and disconnect the tubes? I want to use this cube in an Optical system of Thirlabs. What sort of threads it has? are they SM1 (1.035"-40) ?Question by: Amayas on Apr 15, 2017 1:30:00 PMUnfortunately you cannot remove the 2" nosepiece as it is a single machined housing with the main body of the flip mirror. You can remove the two output ends to expose male T2 threads (M42x0.75). You would need to add a machined adapter to attach any Thorlabs connectors.Answer by: Chris Hendren on May 5, 2017 2:43:00 PMIs the 2" nose piece also removable, if so, what kind of thread does it reveal? Thanks for your time.2 questions:
1) How much backfocus does this flip mirror require?
2) When the mirror is in eyepiece mode does it block all the light to the camera so I can shoot a dark?Question by: Seldom on Mar 17, 2015 9:42:00 PMThank you for your question. The flip mirror is 119mm long so you will need to take that into account
for your imaging train. The light still seeps through the sides when you have it in the eyepiece mode
this would not be suitable for taking darks.Answer by: Rod Gallardy (Admin) on Mar 18, 2015 1:28:00 PMWhat kind of filters does this take? In the Quick Overview, it says 49mm filters (not M48? not M42?) Lower down in the full description, it then says:
"The straight-through port on the Vixen Flip Mirror Diagonal not only accepts many photo adapters but also unthreads to reveal a standard 42mm T-Ring thread."
So, which kind of filters does this take?Question by: Jon Rista on Apr 1, 2015 10:41:00 AMThe flip mirror itself was not designed to take normal telescope filters and the thread inside the 2" nosepiece is 49mm. If you can locate an M49 camera filter thread to M48 adapter, that may work, but most M49 adapters are wider than 2" and would prevent the nosepiece from sliding into a focuser.
If you unthread the 1.25" outputs on each port, they each end in a 42mm T2 thread designed to attach a DSLR or CCD camera (with appropriate spacers). You could use a T2 filter from Astronomik if you wanted, but you would need a separate filter for each output.Answer by: Chris Hendren (Admin) on Apr 1, 2015 5:56:00 PM
