New! Bandmate Type 2 Filters!

New for 2018: Bandmate Type 2 Filters.

We’re excited to jump back into the filter game with our new Bandmate Type 2 Filter series!  Visitors at the recent Northeast Astronomy Forum (NEAF) got the first peek at our initial three offerings and the opportunity to buy as stock arrived just in time for the show.

The Bandmate Type 2’s are premium filters produced for us by Astronomik in Germany. Since both companies are obsessive when it comes to quality control, our product goal is to provide our customers consistency in optical and mechanical tolerances that have plagued the filter industry.  It starts with the materials all being sourced from Germany and ends with each filter tested both at Tele Vue and in Germany.  All filters are individually serialized, and the case shows the average transmission over the passband range. Each filter is also cosmetically scrutinized and optically tested in high power-space to ensure no image degradation before we let them out the door.

Bandmate Type 2 filters are highly scratch and moisture resistant and warranted against manufacturing defects for 10-years.  Filter-types come in 2″ and 1¼” sizes to fit your eyepieces. The first three filters available include the following models:
 
  • Nebustar is a narrowband design specifically made for Tele Vue. Unlike typical Ultra-High Contrast (UHC) designs, Nebustar blocks red wavelengths and so eliminates star bloat to produce sharper, more natural looking stars along with enhancing nebulosity. This is a great general-purpose nebula filter for scopes of any size. 

  • OIII filter passes light from doubly ionized oxygen atoms. As such, they are great for viewing planetary nebulae and supernovae remnants. It is a more typical representative offerings available from Astronomik’s product line but with the tight specification tolerances and additional assurance of Tele Vue’s testing guarantee.

  •  filter passes the aqua colored hydrogen-beta emission lines found in the Horsehead, California, and other hydrogen emitting nebulae.  It is effective for viewing objects that take up the entire field — even when using our wide-angle eyepieces.  Like the OIII, this is a more typical representative offerings available from Astronomik’s product line but with the tight specification tolerances and additional assurance of Tele Vue’s testing guarantee.
