Highlights Maxbright II Bino rotation lock/auxiliary-ring – for the shortest possible adaptation of the Maxbright® II Bino directly onto all Baader T-2 star diagonals, be it prisms or mirrors – without any part in between that would cause an increase in optical length. The Maxbright® II Bino has a male M34 thread exposed, after both alternative adapters have been removed from the body of the Maxbright II. This M34 male thread directly threads into the female M34 thread present in every Baader T-2 prism or mirror. This direct attachment does not leave room between bino and T-2 star diagonal to take up a Baader glasspath-corrector, but on the other hand - the shorter optical length of the combo may be just short enough to not needing a glasspath-corrector at all - so it is well worth a try (exemption: the ) can be fitted in front of any of the Baader T-2 star diagonals). Still the Bino may not bottom out in the right position when fully threaded in while using the described male/female M34 threads. For this reason a dedicated T-2 Locking ring with lever - for MaxBright® II (#2458271) is available. This T-locking-ring will be threaded "upward" against the body of the Maxbright II, to prevent the Bino from unintended rotation and most of all to prevent it to fall off. A T-2 Locking ring with lever - for MaxBright® II (#2458271) , dedicated for the Maxbright-II, is additionally required. This locking ring threads straight onto the male thread of any T-2 star diagonal and the above mentioned Bino auxiliary-ring for adaptation of MaxBright® II (#2458272) is loosely put between binocular and locking ring. The small elevation visible at the locking ring must point towards the binocular and the smooth side towards the star diagonal. This auxiliary-ring works as a cushion, to prevent scratching the paint at the bottom of the Maxbright II while the T-2 locking-ring is threaded upward against the bino. Description Shortest possible Adaptation without Glasspath Corrector In combination with telescopes with long focal lengths (f/10 or slower), it may be interesting to screw the binoviewer directly onto the star diagonal. This gives you a very short (and theft-proof) adaptation, which is ideal for public observatories. In addition, you can screw a T-2 star diagonal directly onto our Baader Diamond SteelTrack focusers with the optional T-2-adapter #?2957202 – very compact, and protected from "accidental removal". To do so, you have to remove the T-2 counter nut or the Zeiss microbayonet. The shortest possible adaptation can be achieved with the Baader Prism Diagonal T-2/90° 32mm (#2456005 , € 110,-) You also need the T-2 Locking ring with lever - for MaxBright® II (#2458271 , € 36,-) and Bino auxiliary-ring. Screw the Locking Ring onto the male thread of the T-2-prism and put the Slip Ring between binoviewer and locking ring. The raised surface of the slip ring should face towards the binoviewer and the flat one towards the star diagonal. Now screw the binoviewer onto the prism and fix it in the desired position with the locking ring. The slip ring lets you still set the interpupillary distance. If the handle of the locking ring ends up in an uncomfortable position, you can change its position. It is only screwed into the ring, you can put it into any of the three threaded holes which are all around the locking ring, each 120° apart.
