The TMB Pro Series UV/IR Cut Imaging Filter is designed to block ultraviolet (UV) and infrared (IR) light, allowing only visible wavelengths to reach your camera sensor. Most telescope optics are optimised for visible light, so blocking UV and IR helps produce sharper, more accurate images with improved contrast and detail.
This filter is ideal for colour CMOS and CCD cameras, and can also be used with monochrome cameras. In addition, it serves as a protective barrier for your imaging equipment, reducing the risk of dust settling on your optics during long exposure sessions.
With its robust optical design and high-quality coatings, the TMB Pro Series UV/IR Cut Filter ensures maximum light transmission in the visible spectrum while minimising unwanted wavelengths, making it a simple but essential tool for astrophotography.
The Astronomik ProPlanet 642 BP is the lastest addition to the family of Astromik ProPlanet IR-pass filters. The filter thrills because of it´s wide range of applikations for daylight IR-Photography, high-resolution lunar and planetary imaging and for taking beautifull and deep images of H-alpha regions when used for Astrophotography.
What does BP stand for ?
"BP" are short for "Bandpass": The filter gives you a 200nm spectral window from 642nm to 842nm. Contrary to the other two ProPlanet filters it blocks the longer infrared. Together with the Astronmik ProPlanet 742 and the ProPlanet 807 you can now have three choices to match your needs when imaging in the IR. The Astronomik ProPlanet 642 BP will be the right choice for the best image quite often!
The Astronomik ProPlanet 642 BP will give you three filters in one single product! Depending on your camera, the Astronomik ProPlanet 642 BP is a great tool either for daylight IR-imaging with your digital camera, or it will reduce seeing effects and enhance contrast when used for lunar- and planetary imaging, and third it will be a very good and low-priced H-alpha Filter for getting started in Deep-Sky Astrophotography of H-alpha regions. Due to our skillfull developement with lot´s of tests we reached the goal to give you a filter which will do a perfect job to deliver amazing images.
Daylight IR-imaging:
contrasty images with a great rendition of colors
Clear "Wood-Effect" images
Not Hot-Spot from longer IR!
Short exposure times, about the same as normal VIS-imaging
perfect choice for Infrared-Videos
High-resolution Lunar and planetary imaging:
short Exposure times
effective reduction of Seeing
enhanced contrast
no ghosts and best sharpness due to blocking the longer IR
Deep-Sky Astrophotography of HII regions:
best transmission of the H-alpha line at 656nm
about 40nm FWHM with astro-modified DSLRs
amazing contrast under lightpolluted skies or moonlight
low priced filter for getting started in H-alpha imaging
easy focussing using camera display plus LiveView!
Guiding for Astrophotography:
installing the 642BP in front of your autoguider-camera dramatically improves guiding quality, as image-motion from one frame to the next is minimized.
Technical Data
more then 96% transmission for wavelengths of 642nm to 840nm
blocking of wavelengths between 350nm and 630nm
Parfocal with other Astronomik filters
Glass thickness: 1mm
Completely resistant against high humidity, scratches and aging effects
Diffraction limited, the filter will not reduce the optical performance of your telescope!
Astronomik filters are delivered in a high-quality, long lasting, filter box
Since 2008 we do ship filters with a completely new design. Any kind of halo or strange reflection is a matter of past
Deep Sky Filter Set Includes LRGB and narrowband SHO filters sized at 19 mm × 12 mm × 1.1 mm. The LRGB filters have an optical density (OD) of 3, while the narrowband filters have an OD of 5, providing high contrast and minimal light leakage for deep sky imaging.
Planetary Filter Set Ideal for planetary observation, this set includes LRGB filters along with a 20nm Methane filter, 40nm UV filter, and 10nm Sodium (Na) filter. Great for capturing fine atmospheric and spectral details.
Photometric Filter Set A complete Sloan filter set: u’, g’, r’, i’, z’. Suitable for scientific imaging and precise photometric measurements.
Ar III Standalone Filter The Ar III (Argon III) filter is a narrowband filter centered around 713nm, designed to capture the specific emission line of triply ionized argon. This emission line is commonly observed in planetary nebulae, H II regions, emission-line galaxies, and in the spectroscopy of ionized gases in laboratory plasmas.
Ideal filters for the reception of the moon and planets, notably Mars, with telescopes from 6" (150mm) aperture.
The ProPlanet IR 742 only allows infrared light with wavelengths of more than 742 nm to pass. In this wavelength range the effects of seeing are significantly lower than in the visible spectrum of the human eye. This allows much sharper images than are usually obtained from your device and location. Another advantage is that the sky background of advanced dawn is dark and so the filter even allows photography of the planets and the moon at daylight.
Main use
The Astronomik ProPlanet IR 742 cuts off the visible part of the spectrum and allows the light of wavelengths longer then 742nm to pass. Due to this behavior the part of the spectrum that is most sensitive to bad seeing is rejected. This approach does a big improvement to the imaging of planets and the moon. The image is more steady than the image in the visible light with nearly identical exposure times.

Other uses
Besides astrophotography the filter allows you to get stunning results in nature photography. If an EOS-Clip Filter is used in an MC modified DSLR you get tremendous results imaging the flora. The filter cuts off the part of the spectrum where Chlorophyll looks green and shows its high reflectivety in the near infrared. If trees are photographed in spring and summer under blue skies you get stunning images with white trees and clouds in front of a near black background.
Darkens the background during twilight.
Imaging of bright planets, stars and comets by day.
Imaging of young stars in dust clouds and stellar nurseries.
Alternatives
When the seeing is very bad and the instrument is 10" (250 mm) or larger, the Astronomik ProPlanet IR 807 may be the better choice.
Ideal addition to the Astronomik ProPlanet IR 742 for imaging the moon and planets, with telescopes larger then 10" (250mm) when the seeing is poor.
This filter is an ideal complement to the ProPlanet IR 742 for use with converted DSLR cameras, CCD cameras and Webcams. The effects of seeing are distinctly reduced. It is your entry into previously unknown dimensions of photography of the moon and the planets.
The ProPlanet IR 807 only allows infrared light with wavelengths of more than 807 nm to pass. In this wavelength range the effects of seeing are significantly lower than in the visible spectrum of the human eye. This allows much sharper images than are usually obtained from your device and location. Another advantage is that the sky background of advanced dawn is dark and even allows photography of planets and moon at daylight.

Other uses
The Astronomik ProPlanet IR 807 is designed to be an addition to the Astronomik ProPlanet IR 742, if the seeing is extremely bad and a larger telescope is used.
For most cameras the exposure times doubles, compared to the Astronomik ProPlanet IR 742 or imaging in visible light, if the Astronomik ProPlanet IR 807 is used.
Darkens the background during twilight.
Imaging of bright planets, stars and comets by day.
Imaging of young stars in dust clouds and stellar nurseries.
Alternatives
If the seeing is not so bad or if the telescope is smaller than 10" (250mm) we recommend the use of the Astronomik ProPlanet IR 742.
