Baader Planetarium

• High precision focusing motor for very heavy loads (up to 8 kg), with temperature compensation
• Timing belt eliminates backlash, fits onto all Baader Steeltrack^® focusers (classic and Diamond), can be adapted to other focusers like the FeatherTouch by Starlight Instruments. Adapters for other focusers than the Steeltrack^® (classic and Diamond) are not included.
• Contactless Homing Sensor for precise homing and repeatable approach of saved absolute positions as well as reference of the mechanical endstop – perfect for remote observatories
• incl. intuitive hand control with back-illuminated keys to quickly change between normal speed, jogging mode and single step mode
• 12 V / 1A PWM power output: e. g. for a dew shield heater. A dew shield heater can be connected with an optional adapter cable (sold seperately). The temperature can be controlled precisely via the temperature sensor(s) attached to the Steeldrive
• Remote-focusing is possible with a PC with USB-port
• incl. powerful SteelGo-software (as download)
• Made in Germany: The housing is made in our house from CNC-milled aluminium. The electronic boards are also made by a German manufacturer according to our design

We will also offer the controller with further application possibilities as well as the focusing motor separately. For the motor we will produce adapter sets for eyepiece slides of various other manufacturers. More information will be available soon.

• M68 extension tube for classic eyepiece projection or Fluoride Flatfield Convertors (FFC)
• 10mm long

• Premium grade H-alpha interline chip CCD-filter for fast optical systems f/10 to f/2.8
• IR-blocked
• NO halos, NO reflections, NO ghosting
• non-ageing sealed coating edges

• Warning: for photographic imaging only
• for solar work use only with 3.8 AstroSolar 200x290mm Photo Film (included)
• never use any eyepiece filter for solar observation without objective front filter
• non-ageing sealed coating edges
• Never look into the sun with the K-Line filter without an additional OD-reduction filter. For more information read the PDF Notes about the stacked 1¼" K-Line Filter

• Triband-SCT's are available in apertures of 8", 9¼" and 11".
• The telescope features:
  • Schmidt Cassegrain optical tube assembly with Triband-ERF-coated Schmidt corrector plate, rear ventilated heat shields for tube and secondary mirror (with Neodymium-magnetic holders)
  • The transmission windows are designed for Calcium-K, Continuum (incl H-beta and O III), H-alpha, S II
• The Triband-coated Schmidt corrector plate reflects more than 90 percent of the incoming light, so that no additional ERF (energy rejection filter) is necessary
• Highest resolution for solar observing at an affordable price
• For the following uses, you need further equipment:
• H-alpha: Solar Spectrum H-alpha filter, TZ-3 telecentric system and telecompressor TK0.4 or TK0.7. An additional D-ERF filter is not required. (T 630 - 680 nm)
• CaK: Solar Spectrum CaK-filter, Baader U-filter for planetary photography in UV. (T 380 - 400 nm)
• Continuum: Safety Cool-Ceramic Herschel wedge and suitable narrowband filters.(T 480 - 515 nm)
• Deep-Sky (not for solar observations!):Deep-sky filters according to your field of interest (RGB / H-beta / O-III / H-alpha / S-II)

We recommend: APF-R image sharpening process

The APF-R method for sharper images was developed by Christoph Kaltseis over the last couple of years. It is based on a simple, but important question: How does a really sharp image look like? APF-R describes this step of image processing in a way.
