Filters against light pollution for astrophotography
This clip filter is especially suitable for NIKON DSLR cameras of the D7000 and D7100 series. It blocks artificial stray light, but retains the natural colors (unlike UHC filters).
The main features of the IDAS LPS-D1 fog filter:
- especially for photography
- high quality anti-reflective coating - anti-reflective coating
- Particularly scratch-resistant hard coating
- Absorption of urban stray light (mercury, sodium vapor lamps) and nightglow
The IDAS LPS-D1 allows a double exposure time extension. The important lines in the deep sky area (e.g. H-Alpha and O III are let through to 90%.
Put simply, you can expose twice as long until the sky background comes through, but the object appears much stronger and more contrast against the background than without a filter.
Targets:
Not only gas nebulae and planetary nebulae can be successfully increased in contrast with the IDAS city light filter - the balanced color behavior also enables pictures of star clusters and galaxies. Even close to cities, pictures can be taken that are more reminiscent of a dark mountain sky.
The filter does not need an optical path.
This means that very short combinations (coma corrector / flattener) can be used, where there is no more space for filter holders between the T2 or M48 connection and the camera. Many telephoto lenses can also be used. The filter also protects the CCD chip from dust.
This clip filter is integrated into the Nikon camera housing of the DX format cameras D7000 / D7100.
The filter comes in a frame that fits easily into the camera body. The filter is simply carefully installed in the housing of the Nikon DSLR camera.
IDAS Filters: specialists in astrophotography
The Light Pollution Suppression Filters (LPS) block the artificial light and leave the natural color. This is exactly what distinguishes these filters from almost all UHC filters in the field of astrophotography. UHC filters are optimized for visual use and cause the sky background to be colored in photography.
The main characteristics of the IDAS LPS D1:
- Specially developed for photography with DSLR cameras and single-shot astro cameras
- It is also suitable for luminance recordings with SW cameras
- High-quality anti-reflective coating - anti-reflective coating
- Particularly scratch-resistant hard coating
- Absorption of urban stray light (mercury, sodium vapor lamps) and nightglow
Exposure time extension - factor 2: The IDAS LPS D1 allows an exposure time extension by a factor of 2. However, the important lines in the DeepSky range (eg H-Alpha and [O III]) are let through 90%. Put simply, you can expose twice as long until the sky background comes through, but the object appears much stronger and more contrast against the background than without a filter.
