7nm Dual Narrow Band Filter is designed to significantly reduce the effects of light harm. The high transmittance and sharp cutoff greatly improves the contrast and gives you the most detailed information when imaging the shiny line nebula, planetary nebula, and supernova debris. 7nm bandwidth means strong separation of nebula radiation into H-Alpha (Red) and OIII (patina)

Enjoy deep space photography even in the city. Enjoy the fun of deep sky photography anywhere in the city. Dual band filters help astronomy enthusiasts take deep sky photos under serious light polluted urban areas and full moon

It is possible to lower the threshold of astronomical creations. The use of dual band filters simplify user post-processing and reduce the hassle of working

Compared to traditional black and white deep space photography, additional accessories and complicated post-processing are required and fade away. Dual band filter allows you to capture full color large screen with one exposure

Ideal filter for use with DSLRs, One Shot Color (OSC), Monochrome CCD and CMOS cameras and astroscopes with a focal ratio of F5 or higher

Quickly capture dark frames to optimize photo quality. The SV164 filter blocks all the light from the imaging camera sensor. Helps improve camera noise and hot pixels Ensures high quality photos especially in astrophotography

2" Standard Filter The SV164 Dark Frame Imaging Filter measures 2 inches. Mix and match devices that accept standard 2" filters

High Quality Filter SV164 Dark Frame Imagination Filter is made of metal. Black anodized exterior Durable, no need to worry about fading or tarnishing

High quality packing box Enclosed foam-lined plastic box holds dark frame imaging filters in place during transport and storage

Various combinations For example, the thread of SV164 dark frame imaging filter can be connected directly to the filter wheel. Quickly switch between different filters, very convenient

Traditional QBP filters were designed to gradually transmit near infrared rays over 900 nm, but when used with an acromatic mirror, a phenomenon of the star clamming halo. This product extends the length of the wavy area of the cut to 1,100 nm (1,100 nm) to reduce the appearance of halo around the brilliance when used with an acromatic mirror. Through the wavelength range around the main 4 shining lines of the celestial body (Hα, HBeta, OIII, SII), and the other wavelength range is cut to make nebula appear even in light polluted areas

Filter Size: American Size

The thread pitch has been changed (inches to mm screws)

Screw Diameter: 1.1 inches (28.575 mm); Thread Pitch: 0.02 inches (0.529 mm); Filter Thickness: 0.06 inches (1.5 mm)

CNC machined; advanced processing can ensure quality; provide more accuracy; consistent results; you can use it with confidence. Good quality and long lasting

Locking Screws Locking function helps to adjust tension and eliminate gaps; double insurance 5. M42-M48 adapter; camera side screw is male Filter mounting screws are female You can use the adapter to connect different camera specifications

Filter drawer thickness 21MM. Knowing the thickness of the filter drawer can help you calculate the back intercepts needed for astrophotography. Thickness is associated with the rear focal length. Back intercept will affect image quality

Black polymers are the most common filter material for observing and capturing sunspots and granular spots using telescopes or binoculars

This sheet is a high quality product from Thousand Oaks Optical, Arizona, a safe solar observation filter manufacturer for over 30 years. Stronger than Mylar Films because of the protected filter action within the substrate. 5 Year Warranty

You can attach your filters to your telescope, binocular or camera at a fraction of the cost of factory filters

Use this filter to see the sun in a natural orange color

WARNING: Please use adhesive tape to ensure that the filter is securely attached to your telescope, binocular or camera to avoid falling out during observation

You can see the moon surface more clearly, not only can you help you see the shadow of the crater of the moon but also help you solve the problem of light pollution in the area

After use, you can easily observe the moon and remove light pollution in the city

Made of aluminum alloy frame and optical glass

Standard 1.25" eyepiece screw interface

The effective diameter of the optical glass is 24mm

Perfect fit, adjustable outer diameter from 118mm to 159mm, screw cap and clamp screws allow the solar filter to be securely attached to the objective lens of your telescope

Solar filter; filters comply with ISO 12312-2; 2015 international standards; ideal tool for watching solar eclipse; do not look directly at the sun without filter protection

Works with existing telescopes; compatible with svbony SV550-122mm telescopes; can be used to observe solar eclipse; black dots less than 100 times

Great view and image This filter features an orange hue that creates a natural look that is perfect for viewing on a telescope or capturing images

Aluminum frame; Compared to other plastic frames, our aluminum frame is more stable and durable

SVBONY Sulfur II 7nm Xtra Narrow Band Filter, transmits 7nm bandwidth light around 672nm, greatly reducing other transmission including light wavelengths that cause light damage

Quality lens material SVBONY 2" filters are made from multi-coated Schott glass with ion-assisted sinking technology to ensure scratch resistance and center wavelength or CWL stability

Sturdy metal frame SVBONY filter cells are made of lightweight and durable metal, CNC machined, sandblasted, black anodized and laser engraved

Standard 2" thread size Insert the metal filter cell directly into the 2" barrel of the telescope eyepiece

SVBONY 2" SII-CCD filters are for astrophotography. You can increase the contrast when shooting objects in deep skies. You can see details that were not previously seen against the night sky

Light pollution reduction filters are a must have in the city due to high light pollution. Removes unwanted light such as street light and allows celestial light to pass through. Suitable for eye observation and photography of nebula, star cluster, etc

CLS filters use high quality optical glass to ensure extreme surface accuracy of the filter for high image quality observation and photography

Cuts out the shine of mercury and sodium lights that are the base of light damage, increasing the number of stars you see clearly

By allowing the light to shine through OIII, Hα, etc., you can increase the contrast of the shooting object

You can also see stars near the horizon, so it is very convenient to observe and take photos. Suitable for color CCD cameras and unmodified DSLR urban optical filters
