According to EU law, we have to display different, country-specific VAT rates in our online shop. In doing so, we try as best we can, the country of origin of our visitors from the IP of the requesting browser. This usually works, but not always.

Baader 2 Inch Highspeed Filter Set - H-Alpha, O-III, S-II - 6.5 nm - CMOS optimized

Narrowband filter set by Baader-Planetarium for astrophotography with CMOS sensors for high contrast for fast telescopes and telephoto lenses from f/3.4 to f/1.8

♦ H-Alpha, O-III and S-II with 6,5 nm FWHM

♦ 2" mounted with filter thread on both sides

♦ Low profile filter cell - height only 6 mm

♦ Optimized for CMOS sensors (Color and MONO)

♦ Especially suitable for fast telescopes, like Celestron RASA, Starizona Hyperstar, TS Boren-Simon Newtonians or fast refractors and camera lenses

♦ Reflex blocker coating against reflections in combination with correctors placed near the filter

♦ Exact and narrow FWHM for optimal signal-to-noise ratio

♦ Identical filter thicknesses for parfocality (not parfocal to older Baader filters!)

♦ Blackened edges

♦ The front side is marked in the form of a black outer edge (front side indicator)

♦ The edge of the filter is sealed, so no moisture can get in

♦ Life-Coat - an even harder coating for a virtually unlimited lifetime

CMOS optimized filters from Baader-Planetarium

The completely redesigned, CMOS-optimized filters from Baader work excellently with all CMOS cameras. The new ultra-sensitive CMOS sensors require special filters to get the most out of the images. These sensors are much more sensitive to reflections and halos. Baader has taken this trend into account with the new CMOS-optimized filters. The filters are the new standard in astrophotography with CMOS sensors.

The features of the new CMOS-optimized filters from Baader:

♦ Increased contrast due to narrower full width at half maximum (FWHM);
♦ Reflex blocker coatings for maximum insensitivity to reflections with correctors, reducers and similar auxiliary optics;
♦ All filters have identical thickness for parfocality - no need to refocus due to different filter thicknesses;
♦ All filters have blackened edges with filter front side marking (black outer edge at the front side), thus additionally avoiding any reflection also at the filter edge;
♦ Each filter is individually fine optically polished and coated, with sealed coating edge. This prevents the penetration of moisture.
♦ Life-Coat stands for an even harder and age-resistant coating, thus the fiter can withstand the most adverse conditions and offers full filter performance even after years;
♦ Each filter comes in a stackable filter box for optimal storage and transport;

Life-Coat: Limited-Lifetime-Warranty for CMOS-optimized Baader filters

Filters equipped with Baader Planetarium´s Life-Coat technology are so durable that Baader Planetarium guarantees the coatings for the life of the filter. Baader Planetarium has developed Life-Coat using materials and processes that result in coatings that will not degrade or age for the life of the filter. Life-Coat coatings resist moisture, temperature extremes and are hardened to withstand normal cleaning.
Baader Planetarium guarantees that the Life-Coat coatings will not peel, flake or physically degrade and will withstand repeated cleaning with fine optical cleaning agents. This limited lifetime warranty applies to the original purchaser and does not cover failures due to misapplication, physical damage due to improper handling or improper cleaning.
