What I need is the SV finder base adapter for the TeleVue Clamshell, part 'Universal Dovetail Base #F1001T' (NOTE: NOT SV's adapter for their own clamshell!).
I will pay up to $25 plus shipping for one of these, though they are only $9 new !!!! Order one off the web and make yourself a profit at my expense.
Why? Because Stellarvue no longer accept foreign credit card orders, so I'd have to pay $50 in bank charges to do a wire transfer.
Shipping to the UK is no trouble - All the taxes and duties are at my end. You'll have to take PayPal (add a 3% charge if you wish).
