- The SV550 APO is a compact refractor with 122mm aperture; f/7 focal ratio and 854mm focal length; a great travel telescope for astrophotography and observation; and even some fainter deep sky objects due to the higher limiting magnitude. It weighs 6.44kg/ 14.18lb; easy to carry out and comes with a carrying case bag;
- The SV550 122mm adopts a FPL-51 triplet apochromatic lens structure which contains one piece of ED glass; the triplet lens provides better correction of aberration and greatly reduces chromatic aberration and enhance the clarity and sharpness;
- The gear ratio of the dual speed 2.5-inch toothed focuser is 1: 10; which makes it easy to achieve accurate focus; the dual speed focuser can provide two focusing speeds by using a set of co-axial knobs; for fast focusing and fine focusing;
- The length of the dovetail is as high as 300mm; it can maintain the balance to the greatest extent; and it will be more convenient in the adjustment process.

Unlock the full potential of your telescope equipment for deep space photography with our versatile and multifunctional accessories! Introducing the SV550 80 APO telescope OTA and SV209 1.0x filed flattener & focal reducer. It is suitable for visual observation and deep sky photography with dso cooled camera.
- Rugged housing prevents damage;
- Sliding graceful and soft dual-speed focuser;
- Ed glass (FPL51) can produce very beautiful and clear images;
- The fully multilayer coated lens eliminates all reflections on the glass, and it has little or no chromatic aberration at high magnification.
- Reduce light pollution; SV220 Dual Narrow bandwidth H-Alpha/O-III 7nm narrowband filter properly designed for astrophotography both in light polluted environment.It can greatly reduce the interference from natural light sources such as moonlight or artificial light pollution such as street lighting;
- Astrophotographic;the filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; the filter allows high-contrast imaging even in areas with strong light pollution;
- Improving contrast; an increase in contrast can be perceived as an increase in brightness; the filter makes the contrast of the nebula and sky background increase; not the nebula brighter;
- Strong applicability; the filter applicable to SVBONY's electronic cameras and astronomical cameras;
- Useful for imaging emission nebulae, planetary nebulae and supernova remnants. Designed to sharply cut off the inference of artificial light from sodium vapor or mercury vapor street lights and other unwanted disturbance like sky glow.
Note: This filter set is not suitable for telescopes with a focal ratio below F/5.

- Cut-off depth ≥OD4; highly efficient in blocking urban light pollution or other background light; use this multi-bandpass filter for astrophotography in urban without traveling long distances to the suburbs;
- Compatible with 99% astrophotography systems; if you have different astrophotography systems, no need to prepare dedicated filters, one SV240 can meet your needs due to its high compatibility;
- Photoing more kinds of targets; SV240 multi-narrowband filter select Ha,OIII,H-Beta wavelength effectively can cover almost photoing needs;
- High transmittance; the >90% transmittance in core wavelength of Ha,OIII, H-Beta, more objects for your astrophotography by using this multi-bandpass filter;
- Multi-bandpass filters; without multiple filters' combination for colorful images; rich color in your lens;
- Resistant of BORTLE 8; the multi-narrowband filters can be resistant from Bortle 1 to Bortle 8 cities, suitable for almost all urban;
- 300-1100 mm working wavelength; the wider coverage of this multi-narrowband filter allows it to have a strong ability to tack light pollution.
Note: Optical filters that use infrared light often cause halos in the NIR region; which are exacerbated by the halos produced by the filter itself.
