SVBONY SII CCD narrow band filter reduces other transmissions, including wavelengths of light that are responsible for light pollution (both artificial and natural)
300-1000nm Wavelength Range; The SVBONY Sulfur II 7nm Extra Narrowband Filter transmits a 7nm bandwidth of light that is centered at 672nm
German imported glass; Multiple layers of anti-reflection non-cementing coatings applied via electron-beam gun evaporation with Ion-assisted deposition
CNC machined and black anodized aero-metal filter cell that is ultra-thin to provide largest clear aperture; Laser-engraved to prevent fading
1.25 inch Mounted; Metal filter cell threads directly into the 1.25 inch barrel of your telescope eyepiece
The SVBONY 1.25" SII Filters are made of glass import from Germany that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength or CWL.

When total solar or partial eclipse happening, it can greatly shorten the searching time using this solar finder scope, you can observe the real-time location of it when the sun moving.
Versatile 60mm aperture Guide Scope with a built-in helical focuser for precise focusing of potential guide stars. Svbony SV106 Guide Scope can ensure that the main mirror accurately tracks the celestial body to be observed. This SV106 is used as a deluxe straight-through finder scope with optional 1.25" eyepieces installed (eyepieces sold separately)
Back Focal Length:220mm
Designed specifically for SV503 70mm, 80mm, and 102mm f/7 ED Refractor.
The field flattener corrects the inherent spherical aberration of curved lenses which causes distortion at the edges of the field of view.
The default back focus is 55mm. 70mm telescope's front end is an M54x0.75 socket to connect to the main lens.

SV179 red dot reflex viewfinder simple, affordable, and effective red dot sighting device makes aiming your telescope.
The SHO filter 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.
