I recently bought a Fornax LT II.
I also have a SWSA 2i with the counterbalance arm and L bracket Dec head.
Rather then shell out $400+ for the Fornax counterbalance, I've been thinking about adapting the Sky Watcher SA counterbalance to work with the Fornax.
My initial thinking was to get a 3/8" mount slim panorama head to fit to the Fornax. This would allow rotation of the counterbalance. These all seem to come with an Arca Swiss type clamp however.
The SWSA counterbalance has a Vixen style wedge so I would need a Vixen clamp to hold it. It seems relatively straightforward to use a Vixen clamp on an Arca plate to connect to the panorama head.
Has anybody out there used a SW counterbalance arm with a Fornax LT II, and if so, how did you manage the interface?
