Fitting a 2-inch BDS-RT Baader Diamond Steeltrack Focuser to a Teleskop-Service GSO 8-inch Ritchey-Chretien
Background
The TS 8-inch RC has M90x1mm connections at the focuser end of the scope. My setup has a TS
50mm extension adapter with for 6- & 8-inch RC connected to the scope (TS part no: GSRCV50),
to accommodate the long back-focus.
Attached to this is a TS M90 tilting adapter flange (TS part no: GSRCJ90). This is an aid to
collimation and allows the long axis of the focuser to be aligned with the optical axis of the scope.
I then have a standard TS monorail focuser for the RC, again with an M90x1 connection.
Image 1 shows the 50mm extension and tilting flange, with the old focuser removed. Note the M90
male thread at the end of the flange, to which the focuser connects.

sidenote... TO THE ATTENTION OF OUR INTERNATIONAL CUSTOMERS!
EU CUSTOMERS: We have temporarily disabled European destinations whilst we adjust our system to the new VAT rules. Hopefully we'll be able to resume shipments to EU countries soon.
USA CUSTOMERS: shipping to the USA is active again, but we request customers to confirm product availability before placing an order! If you are ordering an MGEN-3, no need to check stock, we've got plenty of those. Please note, we will try to avoid sending goods via a postal service due to the huge delays and as DHL Express is more expensive than our system would currently charge for, we might have to charge extra depending on the value and size of the ordered goods.
Please note, due to the increased number if issues with postal services to most directions (especially Australia, Canada etc), we will only ship to these countries on the base of special request and depending on the value and size of the products. This is a temporary measure and we hope to supply worldwide again as soon as the situation improves.
