Your scope will have an SCT visual back, you would need to let us know what filter wheel you have for how best to connect it.

If you can change the nosepiece on your wheel then you need to look for an adapter which connects SCT to whatever your filter is. If the 2" nosepiece is fixed then get an SCT - 2" Push fit female to connect to the scope and create a standard 2" connection.

hi Rossco.. its a brighstar filter wheel and the nose pieces can be removed i got a 2" to T thread with 2"filter threads and T to sct tread adapter ring but neither work

TS Adapter SC Innengewinde auf M48 2' Filter Aussengewinde

This will connect the scope to the wheel.

Is your diagonal sct threaded or 2" pushfit?

[robbie65]

sct threaded

[Rossco72]

Then what you need is a M48 Male thread to SCT Male thread adapter, I haven't found one with a quick search but you could use an SCT male to M48 female and then an M48 male continuous to connect them together.

so is the ts adapter ok for the scope to filter that you gave the link ok

[Rossco72]

The TS link would connect the front of the filter wheel to the scope.

Getting your SCT diagonal connected to the back of the filter wheel is proving harder.

Hi Rossco have you come up with any ideas with the other side of the filter problem

[Rossco72]

You could get one made to order, I had to do this for one of my connections.

Altrnatively if it is only for visual then combine two adapters together as advised above.
