Description

For reducing brightness and during Lunar and Solar observation. Suitable for solar observing only as an additional post-filter!
Fine optical polish results in no loss of sharpness at high magnifications even with a filter position far in front of the focal point.
Phantom Group coated. No ghosting, reflections or stray light.
Threaded both sides of the glass allows combination with other filters (e.g. Baader Color Filters).

Important Information for Observing the Sun

Polarizer and neutral density filters need additional filtering ahead of the scope or eyepiece for any observing of the sun (for example, Baader Herschel Prism or Baader Astro Solar Safety Film). Using without the appropriate safe solar filters can cause permanent damage to the these filters and eyesight.
