Baader Planetarium

• Standard base viewfinder mounting Pairing MQR III, IV MQR, SkySurfer 5 for mounting on the "second telescope" and for all Vixen-style finderscope mount bases
• The Baader standard basis is milled from solid (no cheaper casting), adjusts all Tubusradien and can be with two screws in the slots - but also with a single screw in the center - absolutely firmly attach.
• The base plate is milled sinusoidal and forms on each tube radius 130-400 mm diameter two linear runs. This provides maximum stability.
• Hole spacing: for attachment onto a telescope OTA, the Baader-Standard-Base has two long-holes of 14 mm length each and 5.3mm width, The middle spacing between both holes is 36 mm. Accordingly the center spacing distance of two 5mm screws may vary from 26 mm to 46 mm

• Reducing piece: M68a to M62a for direct connection of M62 accessories (e.g. QHY Color Filter Wheel (CFW 3) (various versions available) ) to the M68 system
• Chonverts the M68 (Zeiss) female into a M62 male thread
• Telescope side M68 male thread, eyepiece side M62 male thread
• Optical length: 5 mm
• Inner diameter: 59 mm, outer diameter: 76 mm

• DT Adapter III, M68a / SP54a extension adapter M68
• Digital T Adapter System III of M68_a on SP54_a Shortest adaptation for Telecentric system or the fluoride Flatfield Converter (FFC).
• This adapter fits to the M68 (Zeiss) ring system - see at FFC (fluorite Barlow) -. Eg to a DSLR camera using the digital T-rings to mount the FFC as short as possible.

• Quick mounting of optics with all EQ standard Celestron / Skywatcher / Vixen dovetail
• Massive but lightweight EQ-clamp, 190 mm (7.5") long w. multi-contact ribbed dovetail face
• Bottom side featuring various predrilled hole patterns to fit onto DEC-face of most mounts (Takahashi, 10Micron, Astro-Physics, Vixen, Celestron)
• With an integrated 3 "dovetail, suitable for all mounts with 3" (Losmandy). Can therefore also be used for adapting telescopes with attached Vixen rails to 3" clamps
• Recommended accessory: 3D-printed ring-wrench for Baader Pan EQ- clamps (#2450071 , € 12,-)

• The two-piece pipe clamp has at the bottom of a 3/8 "thread (a reducer to 1/4" is included) Only in connection with the DADOS slit spektrograph available
• On the top of the pipe clamp has a further 1/4" thread
• The terminal is suitable to attach a telescope as an additional device
• The clip is a must for physics lessons with optimal grip on the optical bench or in any other test setups.

• Telecentric with 2" outer diameter and T-2 threads on both sides
• Aplanatic, with 4x focal length extension to achieve a parallel f/30 beam in conjunction with ~f/7,5 optics systems – free of field curvtare
• Primarily calculated and produced for H-alpha at 656,3 nm, delivering maximum Strehl (definition brightness)

• hand-painted earth globe with graduation to put on the gear box – electrically driven miniature motor for the earth and moon system
• Replacement part for The Original: Baader Planetarium (#2000000 , € 2450,-) – already 1x included with the planetarium.

• Allows direct connection of Baader 2" Zenith Prisms and mirrors to Schmidt-Cassegrain telescopes.
• For Celestron SCTs 8/9.25/11/14 with female 2" thread (5 mm optical length)
• For space-efficient connection of 2 "accessories to the large NexStar telescopes - just the 2" screw housing directly at the telescope.
• In this way you gain 20% field of view and you can connect for example binoviewers with the help of our 2" prisms and mirrors

• 37.5 mm Extension for the IR90  - Integrated Rotating Focuser from PlaneWave to the telescope to gain more backfocus for the Instrument Multi Port IMP85 (#2451300 , € 7950,-)
• Developed and manufactured in Germany   
• Connections on telescope side: PW focuser LK200 5/16 pitch18 UNC 
• Optical length: 37.5mm

• Baader Classic Ortho 10mm 1¼" Eyepiece , apparent field of view 52°, incl. winged rubber eyecup
• Parfocal Eyepiece series with very high transmission
• This eyepiece delivers a pure-white image with outstanding sharpness and contrast
• True High-Transmission- (HT) and Multi-Coating (MC) on all glass-air-surfaces offer a brilliant image while showing almost no internal reflections
• Suitable as projection eyepiece for OPFA (Eyepiece Projection adapter)

• M68 extension tube for classic eyepiece projection or Fluoride Flatfield Convertors (FFC)
• Telescope side M68x1 male thread
• Eyepiece-/camera side M68x1 female thread
• High-quality Aluminum, available in different lengths

• The Hyperion DT-rings are optimized for the shortest distance between eyepiece lens and digital camera lens.

• Baader O-III f/3 Ultra-Highspeed Filter – Premium Grade
• 4 nm FWHM, recommended for fast optical systems from f/3.4 to f/2.3
• Specially designed for the special filter requirements when used with fast f/3 optics
• For highest contrast even at strongest light pollution, minimizes star size, emphasizes finest nebula detail – indispensable under Bortle 9/8/7/(6) skies
• 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

NEW VERSION: Steeldrive II motor focuser with Controller

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

• Both sides 7-layer AR coating with only 0.25% residual reflection per surface. This is the most antireflective that has ever been undertaken with color filters.

• Focal lengths Fine Tuning for Hyperion eyepieces (all focal lengths)
• Optical path length 14mm
• Spacer rings fit between the negative lens and the 2 "barrel, so that it matches the respective eyepiece to your needs.

• 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>
