More details about Steeldrive II

• Filter Frame for D-ERF Filter, Diameter 75 - 180 mm
• No serial production - every filter frame will be adapted to your needs and professionally produced on our in-house 3D-printer (70-160 mm) or are CNC machined Aluminium (180 mm)
• Filter frame offers complete safe and firm hold for the delicate D-ERF energy reflection filters
• Only available in combination with Solar Spectrum H-alpha Filters and D-ERF Filters

• M68 changer for Zeiss adapter system
• Hardened steel - no impressions in the mating surfaces of the dovetail may occur even with the greatest burden

• 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>

• High-precision focusing motor for heavy loads (up to 8 kg), incl. temperature sensor, supports temperature compensation.
• Works with every Baader Steeltrack® focuser (Classic and Diamond)
• Please note: The motor unit requires the Steeldrive II Controller (#2957260 , € 445,-) . You always need one controller to operate one motor unit. But you can use one controller with several motor units one at a time – you only need to plug it into the motor unit which you want to use.
• Can also be used with other focusers like e. g. FeatherTouch. Adapters for other focusers are in development, but not included in the scope of delivery.
• Contactless Homing Sensor enables precise homing and repeatable ap- proach of saved absolute positions – perfect for remote-observatories.
• Can be controlled either with the powerful SteelGo II software or through the ASCOM driver. Needs Steeldrive II Controller (#2957260 , € 445,-)
• Made in Germany: The housing is CNC-milled from Aluminium in our factory. The electronical boards are made by a German company according to our specifications.
