• The SV227 SII filter blocks infrared wavelengths from 700nm to 1000nm so you don't need a separate IR-Cut filter;
• 2 inch mounted; the filter can thread directly into the 2 inch barrel of your telescope eyepiece;
• 300-1000nm wavelength range; the SVBONY SII 5nm 2" Filter transmits a 5nm bandwidth of light that is centered at 672nm;
• This SII narrow band filter reduces other transmissions; including wavelengths of light that are responsible for light pollution;
• The narrow bandwidth and high transmission rate of this filter will make you experience a major boost to contrast.

Note: This OIII filter is NOT for use on the Sun, and is also unsuitable for telescopes with a focal ratio below F/5.

• The SHO filter 5nm 2 inch is highly transparent, allowing the emission spectrum of the nebula to collect as much energy as possible by accumulating exposure. There is higher contrast and the level of the nebula is richer and more delicate.
• This filter set is not suitable for telescopes with a focal ratio below F/5;
• 2 inch mounted; The filter can thread directly into the 2 inch barrel of your telescope eyepiece.

• The SVBONY Narrowband OIII filter is designed for nebula observation allowing 5nm bandwidth of light centered on a wavelength of 500.7nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high- and low-pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere;
• OIII 5nm 2" Filter is designed to deliver 90% transmission at the 500.7nm line which provides you with well defined nebulae structures;
• 300-1000nm wavelength range; the SVBONY OIII 5nm 2" Filter transmits a 5nm bandwidth of light that is centered at 500.7nm;
• 2 inch mounted; the filter can thread directly into the 2 inch barrel of your telescope eyepiece.

• SVBNOY H-Alpha 5nm 2" Filter blocks the transmission of contrast-killing light pollution wavelengths; improve contrast and detail;
• This H-Alpha filter also blocks infrared wavelengths from 700nm to 1000nm so you don't need a separate IR-Cut filter
• Allowing 5nm bandwidth of light centered on a wavelength of 656.3nm to pass through; 90% transmission;
• Astrophotography under a light-polluted night sky can be difficult; the solution is an H-alpha filter; the H-alpha cut-off filter works to filter out a large part of this light pollution;
• 2 inch mounted; the filter can thread directly into the 2 inch barrel of your telescope eyepiece.

Note: This OIII filter is NOT for use on the Sun, and also unsuitable for telescopes with a focal ratio below F/5.

• The Narrowband OIII 5nm filter is designed for nebula observation allowing 5nm bandwidth of light centered on a wavelength of 500.7nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, high- and low-pressure sodium vapor lights and the natural light caused by neutral oxygen emission;
• The H-Alpha 5nm is an extremely narrow emission-line filter that works by allowing a 5nm bandwidth of light, centered on the 656nm wavelength through, and blocking the transmission of contrast-killing light pollution wavelengths;
• The SII 6.5nm Extra Narrowband Filter transmits a 5nm bandwidth of light that is centered at 672nm and drastically reduces other transmissions, including wavelengths of light that are responsible for light pollution. Due to the narrow bandwidth and high transmission rate of this filter, you will experience a major boost to contrast;
• The Blocks infrared wavelengths from 700nm to 1100nm so you don't need a separate IR-Cut filter, suitable for used for deep sky photographic and all are NOT for use on the Sun; 90% transmission of the filters can block the light from mercury and sodium vapour lamps; Standard M28.5x0.6 thread interface, can de directly into the 1.25 inch barrel of your telescope eyepiece.

• SV605MC astronomy camera is designed for deep sky photography. It can be used with other attachments for a series of photography activities;
• It can also be used for moon, planet and sun (extra with solar filter) photography;
• The sensor incorporates a 14-bit A/D converter, the 14-bit digital output makes it possible to read out the signals of 9.07M effective pixels at a high speed of 20 FPS;
• Read-out noise is as low as 1.0e which makes sure the highly suitable for high definition, low noise deep space objects imaging.
