Baader L-RGB CCD-Filterset 1.25" (31.8mm)
US$ 253.47- 4 filters L-RGB
- Ultra high contrast impermeable RGB-Filter, IR-blocked
- NO halos, NO reflections, NO ghosting
- non-ageing sealed coating edges
Optolong L-eXtreme Filter 2" (50.8mm)
US$ 262.24The advantage of the L-eXtreme filter is that there is no transmission between the H-beta and OIII lines, as there is no nebula emission lines there. In this case, it isn't letting light pollution come through so that maximize nebulas signal and make the sky background darker while imaging. The L-eXtreme filter should better isolate the emission lines only and better protect from light pollution.
Optolong Kit L-RGB 2" (50.8mm)
US$ 288.55The LRGB filter kit is designed for maximum contrast and with extremely high gradients for a clear differentiation of light colors
- Improve your view of nebulae with your Celestron Origin, especially from urban and suburban skies. This filter blocks light pollution, increases image contrast and darkens the sky background for sharper, more contrasted images.
- This filter transmits only the key Hα-Hβ-OIII wavelengths from emission nebulae, making their colors stand out from the dark background. It also blocks light pollution, allowing it to be used even from urban and suburban skies.
- Made for the Origin 6" RASA lens. Unlike similar filters with narrower bandwidths, this filter was specifically designed to work with the Origin's fast f/2.2 lens.
- Made of Schott glass with anti-reflective coatings, the surfaces of this filter are completely flat and free of defects.
Optolong L-Ultimate 2" Filter
US$ 341.17The L-Ultimate filter is a practical solution for all amateurs who want to use their telescope from urban and sub-urban areas
Baader L-RGB CCD-Filterset 2" (50.8mm)
US$ 425.37- 4 filters L-RGB
- Ultra high contrast impermeable RGB-Filter, IR-blocked
- NO halos, NO reflections, NO ghosting
- non-ageing sealed coating edges
Daystar QUARK Magnesium I b2-line
US$ 1,314.70Explore highly magnetized and powerful excitations in the bright Magnesium I (b2) line. For use on refractors of F/4 - F/8 focal ratio refractors. This latest and likely the last wavelength offered for Quark reveals a whole new area of highly magnetized high energy in the bright 5172.8Å wavelength. The eye is most sensitive at this wavelength so the image is significantly brighter than calcium. Views show both plage and dark mottling of chromospheric network.
Daystar QUARK Prominence
US$ 1,402.41This new, All-In-One design marries high quality components of a telecentric barlow, adapters, snouts and Daystar hydrogen alpha filter into one simple assembly.
