Questions & Answers

David D : Hello How much backfocus does this device consume for the Camera side?  Thank you. David D
SANG H : I had seen a picture on the Baader website which had shown a 2" Baader eyepiece holder on the top of the flip mirror so I bought 2" Baader eye piece holder (Baader 2" ClickLock Eyepiece Clamp with M48 Female Thread # CLM48-2 2956248), but it was not fit the top of the flip mirror. I guess I bought a wrong eyepiece holder so do you know which eyepiece holder for the top of the flilp mirror I should buy in order for me to be able to use it with a 2" eyepiece?
SANG H : I recently bought a Baader 2" ClickLock Eyepiece Clamp with M48 Female Thread # CLM48-2 for the top for 2" eyepieces, but it was not fit the top. I made a research on the Baader website there was a picture showing a Baader 2" ClickLock on top of the flip mirror. So I think I bought a wrong eyepiece holder. Any idea which eyepiece holder for the top of the flip mirror I should buy for me to be able to use it with a 2" eyepiece?

Awesome accessory for planetary imagining

Excellent for planetary imagining. Planetary imaging is very challenging at high magnification telescopes. The flipper mirror allow to setup a visual and imagining train at the same time. The flip mirror allow to change between them without exchanging trains in the telescope. I was available to center the planet and change back to the imaging train very fast.

WOW!

WOW! I?m a Baader fan for life! I bought this for the convenience of switching from visual and astrophotography. Works as advertised and the build quality is superb. What I did not expect is my view thru my 1.25 eyepiece is twice the size and quality than before. Much more eye relief and no more fish eye.
