    • 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"

    Please note: Since the power requirements of the SunDancer II electronics sometimes exceed the power limit of the previous Baader OTP II 19W: Outdoor Telescope Power Switch with elbowed plug (#2457615, € 26,-) in winter temperatures, the Baader OTP 60W Outdoor Telescope Power Switching Power Supply (#2457630, € 64,-) will be included in the standard scope of delivery of the SunDancer II from 11/2021 onwards at no extra charge.

    We recommend: APF-R image sharpening process

    The APF-R method for sharper images was developed by Christoph Kaltseis over the last couple of years. It is based on a simple, but important question: How does a really sharp image look like? APF-R describes this step of image processing in a way.
