    17,5 mm Morpheus® 76° widefield eyepiece

    # 2954217

    € 245.00 Price excl. German VAT tax (19%): € 205.88
    • 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>

    Large scope of supply:

    • Metal / Rubber eyecup: The folding rubber eyecup now comes with an integral M43 threaded metal ring (this accounts for the complete line of Morpheus-eyepieces). The threaded attachment enables the eyecup to stay soft and compliant, while keeping the eyecup securely attached to the eyepiece while folding it up or down.
    • M43/M43 extension: all Morpheus eyepieces now include the M43 extension #2954250. It is used for optimizing the position of the eyecup in setting the personal viewing position as well as for adapting a camera with M43-thread (eg. Sony / Panasonic). In addition this extension serves also as clamping surface for smartphone holders
    • Eyepiece-Holster: Not enough space at the telescope? The pouch does not only protect the eyepiece – you can even use it as a belt pouch or attach it to your tripod.
    • Focal-Length Indicator-Clips: these stainless steel clips can be attached e.g. to the eyepiece holster and one or more of the little indicator fingers is bent upward - according to the focal length used. In this way the user experiences a taktile ("braille"-equivalent) sensation, being able to identify each eyepiece without looking and without using a flashlight
    • Winged Eyecup: Soft and compliant rubber-eyecap with foldable side shield. Provides the ultimate comfort and exclusion of stray light necessary for binoviewing with eyeglasses
    • 10-page manual: a manual with many application examples and a list of optional accessories (similar to the Hyperion manual) is included (also under Tab "Downloads")

    17.5mm Morpheus® Review

    We appreciate the positive feedback we have received so far. With 3 years of additional development time - the Morpheus 17.5mm was also the most elaborate eyepiece project we had ever started.
    A detailed Morpheus 17.5mm test report has now been published by William Paolini in the most popular astro forums. We are very happy about his extremely positive conclusion and would like to quote the following line:

    The latest Baader addition to the Morpheus eyepiece line up comes across to my eye like they saved the best for last.

    In general the comments on the Morpheus 17.5 and the improvements to the complete eyepiece series (new eyecups with integrated metal threaded ring, index clip, etc.) in the popular forums are quite positive. We would like to pick out the following forum post / test report: https://www.cloudynights.com/topic/609523-baader-morpheus-175mm-televue-delos-173mm-user-impressions/

    • Insert diameter: ∅ 38 mm

    • A Glaspathcorrector is primarily intended to correct the prismatic color fringing that occurs on Refractors due to the high amount of glasses used in binocular prisms

  9.   Baader Neodymium (Moon & Skyglow) Filter

    Baader Neodymium (Moon & Skyglow) Filter

    From: € 79.00 Price excl. German VAT tax (19%): € 66.39
    • The best visual and photographic filter for contrast enhancement for all telescopes, without loss of image brightness!
    • The effect of the element neodymium as filter material is very impressive. When added to optical glass, it enhances contrast, enhances the red colour in the image (especially with Mars and Jupiter) and it darkens the spectral region which is particularly marked by street lamp light, which is the biggest contributor to the nightly "Skyglow".
    • Planoptically polished and MC-coated – with IR-cut coatings!, without any loss of sharpness as a single filter in front of a binocular or be used for afocal projection with digital cameras (far from the focal point!)
    • The IR spectral range is blocked making stars much sharper when used with dSLRs.
    • The Baader Moon & Skyglow Neodymium Filter are two filters in one: Neodymium contrast enhancement filter and UV/IR blocker.

    • Baader Wide-T-Ring to connect Canon EOS DSLR cameras on the Astro T-2 system
    • All Baader Wide-T-rings have an S52 dovetail in addition to the inserted T-2 ring.

With the S52 / M68 adapter # 2458252, the Wide-T-Ring can be directly attached to an M68 male thread to securely fasten your camera to the widest possible aperture.
    • All Baader Wide T-rings can be directly adapted to an UFC (Universal Filter Changer) with the optional Baader UFC S52 dovetail camera-adapter (#2459119), in order to change different filter sizes directly in front of the camera sensor.
    • Furthermore, the illumination of the camera chips improved significantly, mainly because of the larger clear aperture.
    • On the camera side: Canon EOS Bayonet
    • Telescope side: S52 dovetail clamp incl. S52/T-2 internal thread with 0.75mm pitch

    • Blaze Reflection Gratings 1200 L/mm
    • cemented onto Tilting grating holder
    • Please note: Each DADOS spectroscopic grating (especially the 1200 line grating) needs to be precisely calibrated individually for each DADOS-spectrograph. If you order a DADOS together with another of our reflection gratings, this service will be done by us before shipping your order. If you already own a DADOS, we must ask you to return your DADOS each time when you order another grating, apart from the standard 200 line grating. Gratings can be exchanged by yourself later on, if you choose to change the grating resolution. But the initial calibration of the grating in relation to the mechanical body of the DADOS must be one here one time.
      You will only pay for the cost of the grating and the transportation. We will do the calibration work free of charge for the Baader 900 and 1200 line gratings. Please announce your order planning well in advance so that we can plan it in production and provide a comfortable time slot.
