Questions & Answers

MUHAMMAD T : What do i need to attach a 2 inch flattener with this flip mirror?Domokos V : It depends on the camera-side thread on your flattener. The nosepiece of the flip mirror has a female M49 thread. If your flattener has am M48 (2' filter thread) or a T2 thread, then you can find step down rings from M49 to these threads. If your flattener has an SCT thread, then you will need and SCT-thread to M48 adapter and a M49 to M48 step down ring. The distance from the opening of the flip mirror's 2" nosepiece to the end of its square mirror box is 82mm. The round 1.25" ep holders are screwed on the mirror box with T2 threads. --Dom
Kjell D : I have a Meade 6" LS-6 ACF. Is this Vixen Diagonal Flip Mirror suited for my telescope ?ANDREW R : This unit should work with most 'scopes equipped to accept a 2" focuser.
Jorge R : can I use this with my Canon EOS Rebel XS? what else should I need? I already have a T adapter for my camara and my Celestron CPC 1100 XLT. Your advice is very much appreciated since I am a beginner in Astrophotography.ROGER L : Jorge The flip mirror works great with my Explore Scientific scope. As long as your scope has enough back focus for the added length it should work fine for you. The T ring and the Canon adapter is all you need. RogerJOHN H : I was unable to use it with my Rebel XS. You will need a telescope with a lot of back focus because of the length of the device. Furthermore it will create a lot of vignetting due to the diameter and length. If you really want to use an off axis device you need one that is very short and with 2" attachment points.

Handy unit to switch between viewing and imaging

This unit provides convenience to switching between visual observing and imaging allowing a camera or imaging device to remained attached to the straight thru optical path. The only reason I did not give it 5 stars is that the mirror is slightly undersized and does not necessarily provide full field illumination of all 1.25" eyepieces in the 90 degree diagonal position.

Works as advertised but I needed an additional t-adapter for my camera

Works as advertised but I needed an additional t-adapter for my camera. I would recommed it for astrophotography as an aid in focusing your camera.

More than expected with 1 shortcoming

PRO: Works as described. Attaches to both mak rear portal & 2" focuser. With eyepiece barrel removed, G2 DSI attaches directly to body. Solidly built. CON: Eyepiece barrel accommodates 1.25" eyepieces only. Mirror action slow and slightly undersized, neither detrimental to operation. Screw-fitted parts bind when cold.

nice, well built accessory

Received this promptly today from Adorama. I am using it with a 125mm refractor. My DSLR does reach focus with about 1/2 inch to spare so you might want to make sure you have enough back focus. You can use either a 2" or 1.25" eyepiece. To my surprise, there was enough spacing in the front so that I could insert my didymium light pollution filter, although I can't promise you'd have the same luck. I think you'll like it.

The optical path can be switched easily with the changeover knob of the Flip Mirror system, allowing swift transitions from star watching to a tronomical photography. There is no change of the focus point even when switching the optical path. A T-ring attachment thread is provided for direct focus photography.
