Nebula Filters
TeleVue.com: Eyepiece > Nebula Filters > Background

Bandmate™ filters yield bright, sharp and contrasty images — even in the optically sensitive position in front of the diagonal. Optical quality ground and polished BK-7 substrate means no loss of sharpness - even when used in front of mirror diagonals. These complex filter designs are made possible by Ion Beam Sputtering (IBS) technology.

As part of our 100% quality control, every single filter is checked optically and cosmetically to assure performance. Every filter is individually serialized.
