How to connect new Zwo 2600 Duo to 8" RASA

Anyone figured how to fit large aperture adapter 48mm minimum (and where from?) to female 54mm thread on camera?

Thanks but the standard fitting that cones with the RASA is 42mm and therefore covers up the guide camera. Therefore need a RASA fitting with minimum 48mm or better still 54mm - have googled but can't find one

If you can mount your camera onto the standard RASA adapter (42mm) with a step up ring 42/54mm then mark where the guide camera focuser knob is on the RASA mount and drill a suitable sized hole in the RASA mounting plate to allow light through to the guide camera... May need some back focus adjustment for the main camera to meet the 25mm RASA spec's.

just a thought...

Keith,

Been looking at the RASA white paper and the Duo my thoughts are you would need an adapter plate with this type of profile having a 50mm central aperture, with a 54mm male thread to fit the Duo with a thickness to give the required 28.73mm from the back face of the adapter plate to the sensor plane. Should be able to do that but don't have the ali at the mo. Might  build quite a thrist doing this!
