22/04/2020

The long awaited shipment from ZWO has arrived with ASI6200MC-PRO and ASI6200MM-PRO cameras.

At the moment we also have a few ASI533MC-PRO and ASI183MM-PRO cameras.

More shipments will be coming with more cameras, so please contact us or just pre-order any ZWO product, but be prepared for a bit of a delay.  ZWO manufacturing is at full speed, however the delays are due to limited courier services in China. Never-the-less we have several large scheduled shipments from ZWO and will carry on pursuing further shipments to fulfill customer demand.

Baader 2" BDS-RT Diamond Steeltrack RT Focuser for Refractor Telescopes
Baader 2" BDS-RT Diamond Steeltrack RT Focuser for Refractor Telescopes
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. Fitting the Baader Diamond Steeltrack RT It is assumed that the reader has access to the Steeltrack manual and has purchased the necessary RT-Adapter M90x1 Diamond Steeltrack (Baader part nu...
