The nebula filter passes H-Beta, O-III and H-Alpha and is designed for astrophotography.
- IDAS nebula filters are produced in Japan
- The NB1-48 is supplied in a filter cell with M48x0.75 / 2" filter thread
- Exposure time factor 4 - four times the exposure time is possible before you reach the sky background.
- The filter is especially well suited for tricolor shots of nebulae with color cameras
- Scattered light and nightglow are effectively suppressed, leaving stars and sky background relatively neutral
- High-quality anti-reflection coating
- Scratch-resistant hard coating
- With 2.5 mm thickness the filter is parfocal to other IDAS filters
- The infrared light is blocked, so the filter also fulfills the function of an IR blocking filter.

A new corrector for atmospheric dispersion. Now some will say, it's been around for a long time... yes, but this is one of the few on the market that uses plane-parallel cemented wedge plates and thus delivers diffraction-limited images. Due to the specially matched glass types, the corrector is free of image offset and thus free of coma. This is the only way your telescope can develop its full performance potential.
Technical data:
- Overall length: 35mm
- Connection thread: T2 (M42x0.75) on both sides
- Transmission: 17 mm
- Broadband AR coating: 340-900nm
- Surface accuracy: Better ?/10 at 633 nm
