nakbrooks Posted August 22, 2013 Report Share Posted August 22, 2013 My system includes a PL16803 camera with a CFW-3-10 filter wheel - which is large and heavy and offset to one side. This offset causes balance problems as the assembly is mounted on an ASA rotator so the balance changes as it rotates. My solution was to get a brass bar machined which bolts on to the spare bolt holes at the opposite corners of the PL16803 to the filter wheel and has threaded holes to accept a small counter-weight arm I had spare (this is a B&W item originally intended for Meade OTAs). The attached photos illustrate this and I've also attached a drawing. Nigel Drawing.pdf Link to comment Share on other sites More sharing options...
mattssporre Posted August 23, 2013 Report Share Posted August 23, 2013 Smart solution Nigel, What kind of focuser is that - it does not look like an ASA focuser, but you seem to have the Wynne corrector in the package? BRMatts Link to comment Share on other sites More sharing options...
nakbrooks Posted August 23, 2013 Author Report Share Posted August 23, 2013 It's not a focuser (that is on the secondary mirror - my scope is the ASA 400mm classical Cass). What is in the photo is the 4" corrector, ASA rotator, CFW-3-10 filter wheel and PL16803 camera. Link to comment Share on other sites More sharing options...
