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>
