Tele Vue has introduced their new line of Bandmate Type 2 filters!
The Bandmate Type 2 filter offerings will initially consist of OIII, Hß, and Nebustar-UHC models. The first thing you'll notice is that these filters are produced for Tele Vue in Germany by Astronomik. Tele Vue and Astronomik are two relatively small companies that adhere to the same philosophy. Do it better, or don't do it at all; the products, customer, and night sky deserve it.
David Nagler and Gerd Neumann had crossed paths at astronomy shows for years. Both have had their frustrations with the filter business. From passband to thread tolerances, the filter industry seems like the “wild west” of astronomical products. Tele Vue had been looking to develop a long-term supplier of state-of-the-art, custom filters and approached Astronomik with the idea of reintroducing Tele Vue’s line of premium quality Bandmate filters; guaranteed to perform and fit, with uniformity beyond any competitive brand. Gerd and Eric of Astronomik were excited with the idea of a partnership with Tele Vue. “When we started into Amateur-Astronomy, Tele Vue already was a legendary brand known for its outstanding quality of their telescopes and eyepieces. Today we are proud to team up with them to share our knowledge and experience in filter design and production and bring the best filters possible to all astronomers worldwide.”
The distinction you''ll find find with Bandmate filters is their consistency, achieved by keeping control of the manufacturing and quality control processes each company does so well. All the materials are sourced in Germany. Each filter is:
- Optically tested by Tele Vue in high power-space to ensure no image degradation
- Tested by Astronomik on a spectrograph to ensure the coating meets design specifications
- Mechanically tested for fit
- Cosmetically inspected for pinholes, digs, and sleeks and serialized, all to insure your customer's satisfaction.
- All filters are backed with a 10-year warranty against manufacturing defects.
The Hydrogen-Beta filter is a typical representative offering available from Astronomik's product line but with the tight specification tolerances and additional assurance of Tele Vue's testing guarantee.
