# 2456460 Manual Thank you for your purchase of the Baader MaxBright II Binoviewer! Properly used, this sophisticated optical accessory will provide you with a lifetime of amazing views. To ensure optimal performance, please read this instruction manual before using your binoviewer.
Scope of Delivery and Accessories 1. MaxBright II Binoviewer ® 2. Rotatable T-2 Coupling Nut (pre-mounted) 3. Zeiss microbayonet (dovetail ring) 4. Spanner tool to fix T-2 adapter or Zeiss- Microbayonet to the bino-viewer. 5. ABS hard-top case with compartment for a T-2 star diagonal and a nosepiece Please note: This is only the scope of delivery of the MaxBright...
1¼" Star Diagonals The optical length (that is, the necessary back-focus) must be added to the optical length of the binoviewer. Part Number Name Optical Length # 2456100 T-2 Maxbright mirror diagonal 43 mm dielectrical mirror made of Sitall glas ceramic # 2456005 T-2 90°...
Please note: Some T-2 threads may be a little bit too short for the T-2 coupling nut of the MaxBright II. We have incuded a T-2 spacer ring which can be placed into the female thread of the coup- ling nut.
the part of the sky which you can see in it. That's why a 32 mm Plössl with about 50° apparent field of view usually shows already the largest true field of view. Neverthe- less, we have two eyepieces which can show you even more. This is only possible because their field stop is not inside of the nose piece.
Connecting the MaxBright ® Binoviewer to a Telescope There are many options to connect the binoviewer to your telescope. Depending on the back-focus and the optical design of your telescope, you can chose the option which best fits to your needs. Assembly with T-2 Coupling Nut With glasspath correctors 1,25x # 2456314,...
Assembly with Zeiss Microbayonet With glasspath correctors 1,25x # 2456314Z, 1,7x # 2456316Z or 2,6x # 2456317 For this, you need the optional TQC Heavy Duty T-2 Quick Changer # 2456313A . To use the included dovetail ring, you need to remove the T-2 counter nut first. Use the included tool for this.
(im- age below). Insert the GC into the nosepiece and screw the TQC quickchanger onto the nosepiece. Now you can use the MaxBright II with every 2" focuser. This image shows how to insert a glas- spath corrector into the optional T-2/2"...
Assembly with the 2" Glasspath Corrector 1 .8x for Refractors and SC's As described before, attach the Zeiss microbayonet to the MaxBright II instead of the T-2 counter nut. Attach the Glasspath Corrector to one side of the T-2 Maxbright...
Adapting the MaxBright II to the Cool Ceramic Safety Herschel Wedge ® We recommend to use the Zeiss microbayonet in combination with the optional TQC- quickchanger # 2456313A instead of the T-2 counter nut, because you can then screw the glasspath correctors 1,25x and 1,7x directly into the binoviewer. For the 2.6x GC, please see the note at the end of this chapter.
Addendum Addendum 1: The right Glasspath Corrector Back-Focus Sometimes referred to as “in-focus” or “in-travel”, back-focus is an important factor to consider when choosing a binoviewer or any other long accessory (cameras, Herschel Wedge, etc). Back-focus is simply the distance from a telescope's focal point to the surface of its fully retracted focuser.

It also compensates the colour aberrations which would otherwise occur beause of the huge amounts of glass inside of the binoviewer. A GC is more than a simple Bar- low element! The optical design is from Carl Zeiss and Astro Physics – we have tested many lens systems from other sources which only extend the focal point, but which do not remove the colour aberrations.
