Altair 130mm Aperture Energy Rejection filter - Ha Hydrogen Alpha only D-ERF for 5" Refractors
Product Features:
- Reduces approx. 98% of heat reaching the optics to keep Etalon from drifting off-band and protect your equipment.
- 30-40nm FHWM Bandpass at H-alpha (H) wavelength of 656.28 nm (Full Width Half Minimum) Transmission: ~90%
- UVIR blocking OD3 0.1% @400-1100nm blocking over 98% of heat to your 3rd party Etalon at eyepiece or camera end, E.g. Daystar Quark). Please note it's your responsibility to use a proper commercial Etalon with this product, and to follow the manufacturer's instructions.
- Visible light blocking: OD4 0.01% @400-700nm to reduce reflection effects and over 98% of heat.
- Diameter 140mm Thickness 12.0mm
- Multilayer coatings with SiO2 protective overcoat.
- ERF Holder cell included with soft tip threaded knobs. Tough and very light, easy to disassemble for cleaning the filter with optical wipes. Cell does not put any tension on the optics and will not scratch or damage your telescope. It also won't alter the balance as much as an aluminium cell.
