Baader Planetarium

looking for an alternative to others expensive focusers on the market and a good value for money? it is time to take an interest in these Steeltrack focusers. As always with Baader, the finishing is perfect and the telescope has a great look with it. It was not so easy to install because you have to drill your tube. Even if it is thin, the drill bit can slip because the surface is not flat. Do not forget to protect your secondary mirror (for NT) from the filings. You should certainely have to redo your optical lane with the two mirrors, but this is not a hard process. Then enjoy: very smooth, really precise with micro movements, and very rigid.

Not only adds a ClickLock to 1.25" from 2" - the inner T-2 thread connects to Baader T-2 diagonals and many other products as well! Clamp a 1.25" eyepiece in the diagonal, and clamp the diagonal's 1.25" nosepiece in a 2" focuser drawtube. I use these on all my scopes and diagonals. Why settle for thumbscrews in the dark? Nothing beats ClickLock for security and ease of use.

I bought the BDS-SC to use with my C9.25 HD and I tested it on several occasions. I have to say it's an absolute joy to focus with the BDS. It runs very smoothly and allows very fine adjustments. It is big difference to the built-in focuser. The BDS allowed me to re-focus much quicker e.g. when switching to a barlow lens. I find it very convenient that it can be turned without unscrewing anything. The BDS is a very solid build and holds also long imaging trains firmly attached. Both 2" and 3.3" threads fit to the C9.25 HD with or without adapter that came with the telescope, respectively. There are minor imperfections on the inner threads assumingly from clamp attachment during electroplating. All in all I am very happy with the BDS and I think it's well worth the price.

Well made and provides a really secure fit for eyepieces and makes it easy to change eyepieces even when wearing gloves.

Vor wenigen Tagen habe ich einen 2" Diamond Steeltrack BDS-NT incl. SteelDrive erhalten und damit meinen bisherigen 2" OAZ (hochwertiger Hersteller mit Focus-Stepper) ersetzt. Der Umbau ging extrem leicht von der Hand und ich darf an dieser Stelle sagen: Was für eine tolle Qualität! Ich bin total begeistert von der Steifigkeit und der Stabilität! Es rutscht nichts durch (trotz 2,5kg-Kamerakopf incl. Korrektor, Filterrad usw.) und es wackelt und federt auch nichts. Die Kollimierung bleibt bei meinem 10"er nach einem Meridian-Flip einwandfrei erhalten! Auch das Positionieren des Auszuges mittels SteelDrive funktioniert wie aus dem Lehrbuch - ohne Backlash!! Einen herzlichen Glückwunsch an das Baader-Team für dieses extrem durchdachte Produkt!
