More details about Steeldrive II

• Silently heated H-alpha-Filter with integrated 3x telecentric system with 2nm block filter.
• Half-width (FWHM) of 0.6±0.1Å at an effective focal ratio of f/30
• Resistant to ageing: The dielectric coating of the blocking filter and the airtight storage of the SolarSpectrum Etalon filter in oil prevent the ageing process
• The complete disk of the sun as well as prominences are visible in telescope with focal lengths up to about 600mm
• shows prominences and solar surface details for visual observations as well as for photography and bino-viewers
• For telescope with 80mm aperture or less, no additional D-ERF (energy rejection filter) is necessary
• Userfriendly electrical temperature control; additional micrometer screw for observiong fast changes in the blue wing of the H-alpha-line
• Nosepiece: 2", 1,25"

• Eyepiece 1¼ "/ T-2 internal thread priced version with M 4 screw
• 1 M4 clamp screw
• 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>

• Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
• Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
• Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies

• suitable for temperatures from -55°C up to +30°C
• excellent grease-quality for low temperature application as prevailant at polar-circle regions
• not suitable for permanent use at temperatures above 25°C

• Baader SLOAN-u' Bandpass Filter, suitable from f/15 to f/1.8
• SLOAN/SDSS (ugriz’) photometric filter with transmission according to SLOAN-specification

• Equally suitable for modern CMOS cameras as well as for older CCD camera technologies

• For locking camera orientation
• Fits between (almost) any of our T-2 fittings
• Allows the rotational rotation of flanged accessories, locking in the appropriate position
• An important component to heavy CCD cameras to connect directly with T-2 thread without the compromise of a plug connection

• Baader levelling flanges are used to adjust the unevenness of the foundation or the concrete pillar as well as other deviations of the substructure from the perfect north-south alignment. They adjust these imperfections as close as possible to the mount, very precisely and steady, without reducing the stability of the pillar
