Celestron LPS nebula filter for RASA 8 astrographs - increases contrast by suppressing stray light
- The Filter is screwed into the M55 filter thread of the RASA8 telescopes.
- The filter does not alter the working distance, the normal connection adapters can be used further on.
- The filter transmits the light of emission nebulae and block the light pollution from artificial lighting. So you can expose 4x longer.
- Schott glass with anti-reflex coating prevents from unaesthetic reflexes on the image.
- The filter works optimally together with the modern color CMOS sensors of astro cameras and system cameras and provides good color correction.
