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 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. -

Before you start exploring the Sun it is very important to be informed about all the possible risks of solar observation. Please take a careful look at the manuals of all the equipment and filters before pointing your telescope at the Sun. © Baader Planetarium GmbH | 2020... -
Page 18: Adapting The Maxbright ® Ii To The Cool Ceramic Safety Herschel Wedge
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. -

Page 20: Addendum
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. -
Page 21: Choosing A Glasspath Corrector
By using a Glasspath Corrector, the focal point of the telescope can be extended sufficiently to ac- commodate the length of the binoviewer. © Baader Planetarium GmbH | 2020... - Page 22 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.
