I'd like to let you know that we've just received a big shipment of various ZWO products.
New series of full frame cameras are available from ZWO now.
We got the ASI6200 MONO and COLOUR full frame cameras, the APS-C sized ASI2600MC-PRO that is only available in colour, and the ASI533MC-PRO is back in stock again. As the ASI6200MM-PRO is the first full frame monochrome camera of ZWO, they also developed appropriate accessories for this, i.e. 2" filter wheels (5 and 7 position versions), M68 OAG (Off Axis Guider adapter), 2" LRGB filters and 2" narrowband filters (7nm H-alpha, OIII and SII).
All these also arrived, except the narrowband filters that we expect a bit later.

You might have also noticed that we listed various Astrotrac products recently. We will receive stock at Astrofest at the end of the month and there will be a special introductory promotion of these at Astrofest, so if you wanted the finest and probably most beautifully engineered mount on Earth, come and visit us at Astrofest.

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...
