Product information "EXPLORE SCIENTIFIC 1.25" O-III Nebula Filter 6.5nm"
One of the most important obstacles for the exploration of the night sky
is the brightening of the night sky by artificial lighting, such as
streetlights. The night sky is not really dark in the vicinity of towns
or cities, which reduces the visibility of objects beyond the solar
system enormously. Depending on the type of celestial object, it is
possible to increase the contrast dramatically by blocking the interfering artificial light.
FEATURES
The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so-called emmission nebulae.
Those objects glow in special colors, the so-called emmission lines.
Those emmission lines are linked to chemical elements - in this case
oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the two emmission lines of the oxygen can pass the filter.
The result is astonishing: suddenly, nebulae are visible in locations
that were completely empty without using filters. In suburban skies, for
example, the veil nebula NGC 6992 is almost invisible with a 200 mm
telescope. By using this filter you can see the nebula and its
structures without any difficulties. A must for every visual observer and for astrophotography.
The EXPLORE SCIENTIFIC nebula filters come with an individual test certificate - your guarantee for receiving a premium filter.
This filter's narrow passband of only 6.5 nm bandwidth highlights the
faint emission nebulae or makes them visible even under difficult urban
conditions.
- enables the observation of so-called emmission nebulae

- band pass width: 6.5 nm
- narrow band version for difficult urban conditions
- allows more contrast for faint deep sky objects
- ideal for use near cities, in heavy brightened skies

The EXPLORE SCIENTIFIC S-II filter uses the property of the so-called emission nebulae. These objects glow in certain colors, the so-called emission lines. The emission lines are associated with certain chemical elements - in this case ionized sulfur. The EXPLORE SCIENTIFIC S-II nebula filter blocks all other colors (and thus almost all artificial light) and lets only the emission lines of ionized sulfur at 672 nm through. The effect is amazing: suddenly, nebulae become visible in places that appear completely empty without the filter. In slightly brightened skies many planetary nebulae, emission nebulae and supernova remnants can be seen without any difficulties when using this filter. A must for every visual observer and for astrophotography.
EXPLORE SCIENTIFIC nebula filters come with an individual test report - so you can be sure to get high quality filters.

Apart from air turbulence, the brightening of the night sky is the greatest
barrier to observing faint objects beyond the solar system. Due to
streetlamps and other artificial lighting the sky in urban areas is no
longer properly black. As a result, the contrast and thus the
perception of deep-sky objects also suffer. However, depending on the
type of celestial object, it is possible to filter out some of the interfering light making it easier to photograph the objects.The EXPLORE SCIENTIFIC H-Alpha filter uses the characteristic of the so-called emission nebulae.
These objects glow in certain colors, the so-called emission lines. The
emission lines are associated with certain chemical elements - in this
case the red glowing hydrogen. This filter blocks all other colors (and therefore almost all artificial light) and lets only the emission lines of hydrogen through. Especially the disturbing light of mercury and sodium vapor lamps is effectively blocked. The effect is amazing: Suddenly, nebulae become visible on the photos in places which appear completely empty without the filter.The EXPLORE SCIENTIFIC H-Alpha Nebula Filter has been developed exclusively for astrophotography. Especially in heavy light-polluted skies many emission nebulae are only visible and shown in full expanse on astrophotos when using this filter. The H-Alpha nebula filters make astrophotography near the city possible and the use leads to amazingly good image results despite the existing light pollution. A must for every urban astrophotographer.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure to get high quality filters.This filter's narrow passband of only 7 nm bandwidth works out

EXPLORE SCIENTIFIC OPTOLONG 1.25" L-Pro Deep-Sky Light Pollution Filter
€169.00*
LPS filter L-Pro for deep sky nebula constellation photography.The relentless spread or urbanization and its associated light pollution
have become a growing problem for all amateur astro photographers. The
current solutions to the problem can be expensive and might include the
purchase of a monochrome camera, several types of narrowband filters and
a filter wheel. Especially with inexpensive newtonian telescopes,
double-lens ED refractors or even achromats, the L-Pro filters open
up completely new possibilities for the capture of high-class
astronomical images even out of the light polluted city. CMOS cameras
can deliver images like monochrome cameras. This new generation of
filters makes it possible to take amazing astrophotos directly from the
light-polluted city with all its artificial light sources.
L-Pro is a multi-bandpass filter which offers better color balance by
maximizing the transmission band. The balanced transmission allows
astrophotos to be taken with minimal color cast to broadband emission
objects such as galaxies, reflection nebulae and globular star clusters.
L-Pro is the best choice for light pollution suppression. L-Pro description L-Pro
(L-Professional) filter is designed to improve the visibility of
various deepsky objects. By selectively reducing the transmission of
wavelengths of light pollutants, specifically those produced by
artificial lightings including mercury vapor lamps, both high & low
pressure sodium vapor lights and the unwanted natural light caused by
neutral oxygen emission in our atmosphere (i.e. skyglow). Together with
the highly transparent in main nebula emission lines at OIII (496nm and
500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm) as well as
SII (672nm), the filter is suitable for enhancing the contrast and
details for both visual and photograghic purpose at sub-rural areas with
heavy light pollution.
L-Pro is a multi-bandpass filter which offers better color balance by
maximizing the transmission band. The balanced transmission allows
astrophotos to be taken with minimal color cast to broadband emission
objects such as galaxies, reflection nebulae and globular star clusters.
L-Pro is the best choice for light pollution suppression. Main use and performance Suitable
for visual observation and astrophotography.
L-Pro filter has a very low transmission reduction rate against
continuous spectrum space objects, and thus is quite effective in
suppressing light pollution sources when shooting galaxies, reflection
nebulae and globular star clusters. The same holds true for visual star
observations.
L-Pro filter alone can suppress infrared wavelength, and thus can be
used at ease for ''L'' image shootings with CCDs.
Light pollution filters do not eliminate the effects of light pollution
or increase the object’s brightness. In many cases, they increase the
contrast between nebula and night sky, not brightening the nebula. WARNING: These nebula filters are not designed for sun observation. DO NOT LOOK AT THE SUN WITH THIS FILTER. You will go BLIND if you ignore this warning.Coating technology L-Pro has a multiple anti-reflective coating on the optical substrate. The L-Pro filter uses a precision coating based on ion deposition coating technology. This ensures durability and scratch resistance as well as stability on the CWL (central wavelength), which is not affected by temperature changes. Absolute precision and homogeneity of the coatings as well as maximum values for transmission in the passband and optical density in the off-band range are guaranteed for all filters.FEATURES Professional visual and photographic filter for astronomy Improves deep sky nebula constellation photography Best choice for broadband light pollution suppressionFilter diameter: 1.25 inch / 31.7mm Connecting thread: M28.5 x 0.6mm (Eyepiece thread 1.25 inch)Selected optical glass material Spectrum: 380-750nmSurface Quality: 60/40 (Refer to MIL-O-13830) Fine-optically polished glass to ensure accurate 1/4 wavefront and highest parallelism over the both surfaces High transmission at major nebula emission lines (i.e. H-alpha 656nm, OIII 496nm&500nm, SII 672nm and H-beta 486nm)Precision
