Rings and Plates

Both ways are possible and work equally good. We recommend to attach the Barlow to the 1.25" nosepiece of the Hyperion Zoom with the Adapter A, because this is more sturdy and also works with all other eyepieces.
But you can as well remove the 1.25" nosepiece from the Hyperion Zoom if this is better suits your needs. So, both options work equally in regards of optical performance, and you freely chose the mechanical adaption which you like better.

Unsere Lösung um einen UFC an den RASA8 anzuschliessen wird bald verfügbar sein, jedoch noch nicht jetzt (15.Apr.)
Es können Kameras mit bis zu 13mm Backfokus angeschlossen werden, z.B. ZWO mit abschraubbarer Verlängerung/Umkehrring mit 11mm.
Vielleicht möchten Sie unseren Newsletter abbonieren um frühzeitig darüber informiert zu werden wenn der UFC für den RASA8 verfügbar ist.

The shortest adaptioation is probably
- Takahashi Adapter M72/M68 (Zeiss) # 2558230, optical length 10mm
- M68 to 2" UNFi Conversion Ring # 2458232 (that's the female SC-thread), optical length 5mm
- Baader 2"/2" Inverter Ring with 48mm filter thread # 1508020

Then you just have to remove the 2" nosepiece from the prism and insert the inverter ring, so that you can attach the M68 und the M72 adapters. But please note that this is a fix connection, which you can't easily rotate.

If you want to rotate it (and can't rotate the whole focuser), you can use in addition
- Baader M68/S68 Changer to fit Zeiss adapter system (dovetail clamp only) # 2458180
plus
- Baader M68/S68 steel change ring to fit Zeiss adapter system (dovetail-ring only) # 2458185
with a combined length of 25mm.

Instead, you could also use
- Takahashi Adapter M72/M68 (Zeiss) # 2558230, optical length 10mm
- Baader Ultrashort 2" eyepiece clamp # 2458196, optical length 12mm
and use the prism with its 2" nose piece. Then you can clamp the prism like any standard 2" accessories and rotate it as you like it.

First you need this adapters that you have access to a wide range of further accessories by the common M68 Zeiss thread:

Then, for example, you can screw on this Items:

An alternate if its back focus critical:
