This useful star diagonal for 2" focusers accepts two 1.25" eyepieces and incorporates a flip-mirror that enables you to switch between them for alternate views.
The 1.25" eyepiece holders can also be unscrewed to reveal industry-standard T2 42mm threads that will accept a 35mm camera fitted with a T-ring, so allowing you to observe through an eyepiece then switch to a camera for imaging. Ideal for terrestrial and astro photography.
It's 2" barrel is threaded for 49mm filters (a 49-to-48mm step-down ring is required for use with 48mm photographic filters).
Product arrived quickly to Ireland which was great. I have a Celestron Evolution 8" SCT however for the flip mirror to attach to the telescope i need an adaptor such as Baader SCT to 2-inch adapter as on this website and for a dslr need a t-ring.
this is a great idea and it works very well with a DSLR connected to the rear port and an eyepiece in the top. A simple flip switches between the two. The big let down is the fact that it ill not accept Skywatcher or Baader light polution filters. A step down ring is required but all the ones I have tried have too large a diameter and will not insert inside the focus tube. So it's a bit of a design flaw. I ended up taping the filter to the tube. not very professional. If this issue was sorted out it would make a good product fantastic.
I got it lately, the "made in china version". I wanted to screw it to the filter wheel, but the counter ring was loose on the thread for some reason. But the T-thread on the camera side is surprisingly a T2 thread inverter adapter (T2 male on both sides), so I used a Baader continuous T2 male + the counter/locking ring which did the job. On the 2" nosepiece is threaded for photographic filters, so 2" won't screw in. (what's more likely - a 2" filter or a photographic one?), Aside of that it works, it's short and lightweight.
