Baader Planetarium

• Filter changer and Tilter (mechanical image position corrector), specially designed for Celestron RASA 8" Astrograph and QHY cameras with 90 mm diameter (e.g. QHY 268M (version before June 2023) / 294 / 533)
• The Baader FCCT (Filter Changer Camera Tilter) allows the use of filters as well as the adjustment of camera plus filter to the optical path
• With the FCCT, a very fast adjustment or finest readjustments are possible - without having to unscrew the camera each time. This makes working with the RASA 8 a pleasure
• 3D-printed filter sliders are available for the FCCT, which exclusively accommodate unmounted filters with diameters of 31 mm / 36 mm and 2" (w/o cell)
• We offer selected 2" filters specifically for the FCCT in an unmounted variant, but basically all Baader 2" filters will work when removed from the filter cell

• Filter holder with T-2 threads on both sides and 1¼" M28.5 internal filter thread.
• Used for attaching 1¼" filters before Baader binoculars
• A 1¼" filter can be attached from either side and will sit within this adaptor

• Enables the use of up to three instruments at the focal plane of a telescope.
• Designed, manufactured and assembled in Germany
• The light passes through the IMP either undisturbed to the rear port (port 1 with 85 mm free diameter), or it can be deflected to the left or right (ports 2 and 3 with 67 mm free diameter) via two automated 40 x 40 mm mirrors with BBHS coating.
• Can be controlled by a keypad or remotely via a webinterface.

• Replacement halogen bulb including ceramic socket
• Consisting of  Replacement bulb (Halogen) without socket (#2000317 , € 33,-) and Ceramic holder for halogen bulb (#2000318 , € 24,-)
• Replacement part for The Original: Baader Planetarium (#2000000 , € 2450,-) – already 1x included with the planetarium.
• Please use only this bulb, otherwise you may destroy the transformer of the device, which due to its size can not give more light output. For continuous operation (3 hours and more) you must use the medium light level.

Steeldrive I for Classic Steeltracks is not produced anymore. On this product page you can inform yourself about the Steeldrive I for classic Steeltrack focusers and download the corresponding software.

More details about Steeldrive II

• Colour Filter Set with 6 colours for contrast enhancement of lunar and planetary observations.
• Largest free opening of all the colour filters on the market which eliminates any vignetting.
• Double 7-layer anti-reflection coating with only 0.25% residual reflection per surface (Phantom Group Coating) resulting in no reflections, scatter or dimming.
• Planeoptically polished for sharp image at high magnification.
• Included Filters: Dark Blue Filter, Light Blue Filter, Green Filter, Yellow Filter, Orange Filter and Red Filter
• Non-ageing sealed coating

• 1¼ "/ T-2 eyepiece with fine focus (5mm focus travel)
• With three eyepiece clamping screws for fine centering - as well as rotation locking screw to secure the exact focus position
• Telescope side with T-2 internal thread
• For 1¼" eyepieces or connecters

• Temperature sensor to compensate the drift automatically, if there are large temperature differences
• Flat design, ideal to be attached to the optical tube
• Temperature sensor with phone connector and 1m cable, also supports control of dew-shield-heating
• Can be used with the Steeldrive II Motor Unit or Steeldrive II Controller

• Full field sharpness: The ultra-sharp 76° undistorted flat field is unsurpassed by any other modern wide field eyepiece. Also on-axis sharpness and contrast rivals our best, ever released planetary eyepieces, the Zeiss Abbe ZAO I & II.
• Long Eye Relief and optimized for bino-viewing:  ~ 20mm of eye relief provides that famous spacewalk feeling, incredibly impressive with bino and both eyes.
• Hard aluminium alloy with industrial quality UV-stabilized anodizing surrounds a set of 8 lenses with one ED- and two Lanthanum elements.
• 2" and 1¼" nosepiece: integrated into one eyepiece of 55mm max outer diameter, supports bino-viewing even for kids.
• Photo-Video Adaption: Like their Hyperion siblings, all Morpheus eyepieces make superb imaging projection optics with the M43 photo/video-thread
• The Morpheus 17.5 mm is the only eyepiece of the Morpheus series that is not parfocal to the rest of the series. It requires 2.5 mm infocus.>/li>
