[Ali7 (Ali)]

Hi, Did anyone successfully find an adaptor to connect Zwo 120mm mini guide camera to Sky-Watcher Finder 9x50?
Thanks

there is an adaptor for the 9x50 finder to attach a guidescope.
you will need to find a 3d printer to do so.
I doubt there is an option off the shelf.

There are helical focuser add-ons available for ezxactly this. The direct version is hard to find now (it's M50 thread or something obscure like that), but there are other options on eBay/AliExpress etc. They look like this: https://www.ebay.com.au/itm/SVBNOY-1...0AAOSwTmRdPAsd - that one has an M42 fitting, so you'd need to have a custom adaptor made from M42 to the odd SW thread.

I have one of the original helical focusers that were around for a few years and it screws right onto the back of the SW 9x50 finder perfectly with no adaptor - haven't seen them in a while. I'll post a picture later.

This is the one that screws onto the SW finder directly:

Note - click the first picture it is the helical focuser by itself for $57. If you select the second picture, you get the focuser PLUS a new finder etc for $150

You can buy them from Modern Astronomy in the UK.

As George alluded to above, the add-on helical focuser is great - here is mine added to a SW 9x50 used as a guidescope (note the Lodestar inserted in the focuser). This is the direct to tube version - no adaptor / stepper required. I note Aliexpress sell them for $55 AUS, post extra.

I got mine for around $60 delivered. No need to mess around shifting the guide cam in and out as the helical focuser (non-rotating) has a good amount of travel.
