More details about Steeldrive II

• Using this device, you can check instantaneously the seeing value in arc seconds at your specific location
• Shows instant seeing value, light input and 1 minute moving average
• Separate sensor can be placed next to the entrance pupil of your instrument
• Runs on battery or USB

• Holds all all Zeiss devices - with 68mm thread (with 19mm optical height)
• Keeps all Vixen Optics - with 60mm thread on the focus tube (with 24mm optical height)
• Keeps all Astrophysics refractors with 2.7 "thread (with 13mm optical height)
• Keeps all Skywatcher- / Celestron refractors, all Synta optics - with 56mm thread on 2 "eyepiece holder (with 31mm optical height)

• Holder to attach the Steeldrive II Controller to a 3" Dovetail
• Suitable for all 3" (Losmandy standard) dovetail clamps
• The controller is inserted into the holder and can be quickly removed for manual operation.
• The holder helps to lay cables cleanly for remote setup

• 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>
