Mounting eyepiece diameter: 1.3 inches (31.7 mm)

Effective diameter: 0.7 inches (19 mm)

Neutral Density Equivalent to ND4

Uses a ND filter that effectively diminishes the moonlight

This UV/IR filter can block bad UV and IR rays. Because its bad light can prevent digital sensors from taking high contrast and high quality images

Used as a permanent lens protector, it is useful for DSLR cameras, CCD cameras and modified WebCams or telescopes digital imaging

The production optical quality glass substrate and coating allows for greater detail, reduced chromatic aberration, and more natural and fine color gradation

SVBONY filters are a good choice for DSLR cameras, CCD cameras, and improved WebCams, or telescopes digital imaging

UV/IR cut filters use the latest coating technology to ensure high permeability quality and long service life. UV/IR cut filters can be combined with other filters and then attached to an eyepiece or camera adapter to reduce chromatic aberration. So it can not only take sharp images but also reduce ghosting images caused by IR radiation

Double Pair of Magnets Compared to traditional screw rotation. Magnets have stronger adhesion. Convenient to install and use. Two filter holders Standard 1.25" and 2" filter holders Plug & Play; Reduces disassembly and assembly procedures repeatedly in dark environments

Fits 1.25" and 2" filter mounts. Also works with existing 1.25" and 2" filters. For beginner photography. Save money on changing filter size

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

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

1.25" ND Moon Filter Reduces glare and allows you to see more details of the moon and surface features on the telescope. Will not change the natural color of the moon

Use ND4 filters at 25% transparency during crescent months. When the moon moves around the earth, using ND4 filters is very good at this point, and you will see more and more of the illuminated half

Uses ND8 filters with 12.5% transparency when the upper and lower string. Excellent effect when using ND8 filters at the upper and lower string

For 18 nights, use ND16 filter with 6.25% transparency. Lighted areas of the moon are shown to decrease It is very good to use ND16 filters in the first week after full moon

When full moon, use ND1000 filter with 0.10% transparency, you can see the full moon, and it is very good to use ND1000 filter when the moon is brightest

Filter Diameter: 1.9 inches (48 mm), Made in Japan

Depending on the telescope or lens, it may not be able to install it. Product features depend on the angle of the light coming in. It is recommended to be used with a telephoto lens or telescope for proper performance

When used with a square lens, the screen will have uneven brightness and color balance. Please adjust the color balance of the image when photographed using the commercially available image processing software

Product specifications may change without prior notice due to improvements. Please acknowledge

Perfect fit, adjustable outer diameter from 80mm to 118mm, 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 SV550-80mm 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

Filter filters out unwanted light (light pollution) such as street light when observing and shooting nebula, star cluster, comet, etc

Cuts out the shine of mercury and sodium lights which are the base of light damage, which helps to tighten the sky and increase the number of stars you see clearly

By allowing the light lines such as OIII and Hα, you can capture nebula with high contrast

Using high quality optical glass, the filter surface is extremely precise and allows you to observe and shoot in high quality

You can also see stars near the horizon, so it is very convenient to observe and take photos

Cut-off Depth ≥ OD4::SV240 Multi-Band Pass Filter blocks light pollution and can be used in BORTLE 1 to 8 cities. Capture clearer and contrasting astrophotography in cities without going to the country

Wide application: SV240 multi-band pass filter can effectively choose Ha;OIII;H-Beta wavelengths. No need to use multiple filters to solve the problem of traditional filters is not suitable for galaxy or star clusters and capture most deep sky objects

Wavelength Range: Near infrared (NIR) blocks wavelengths up to 1100nm. It has a strong processing capacity of 300-1100nm wavelength, which can effectively isolate the light harm

FWHM: 25nm; 22nm; 115nm; Hα, OIII, Hbeta wavelength range SV240 multicolor low band filters allow you to capture colorful images

BORTLE 8 RESISTANCE: Multi-band pass filters are resistant from Bortle 1 to Bortle 8 cities and are suitable for almost any city

Multi-layer Coating: SV240 is coated with multiple layers of film such as bumper layer, waterproof layer, adhesive layer, etc. Due to the superior coating process, the SV240 improves the S/N ratio and contrast of your images while maintaining a good color balance

Note: Optical filters using infrared are often halo in the near infrared area, and the halo effect will deteriorate due to halo overlapping which creates the filter itself, so please buy with caution

SECURE Astronomical Telescope Accessory Set: Beginner telescope accessory set. Includes 2 PL eyepieces, 2 barlow lenses, moon filter, ND filter, and blue planet filter

PL Eyepieces: 2 PL Eyepieces(6mm + 17mm) Basic Eyepiece to meet your daily needs, you can replace two sizes Premium optical glass is used in lens material to provide clear vision and superior contrast. And the lenses are multi-coated for a sharper image

2x Barlow Lens: The Palo lens can extend the focal length and allows for higher magnification observation with your eyepiece. The image is flat and balanced to correct chromatic aberration, and knot clear images

ND4 Filters: ND4 filters only transmit 25% of incoming light Helps reduce radiation. Reduces the change between light and dark areas of the moon end. Helps protect your vision when viewing the moon surface. Suitable for watching crescent moon As the moon moves around the earth, the illuminated half becomes more and more visible. You will get that sliver first. It grows over the day. This phase is called crescent moon. At this point, the ND4 filter is very good

Moon Filter: 1.25" Moon Filter is a multi-band pass filter that can transmit high percentage of light in the visual spectrum. This filter can increase contrast when observing bright objects such as the moon and planets

82A Blue Filter: 82A blue filter can be used with the moon and most planets to emphasize low-contrast areas without reducing overall brightness of the observation
