1. SVBONY SV115 Telescope Filter O-III Filter Narrowband Cuts Light Pollution Filter for Astronomy Telescope (2 inch)
Telescope filters can be a great way to improve your viewing experience, by blocking out or reducing certain types of light. There are many different types of telescope filters available on the market, but one of the most popular is the OIII filter.
The OIII filter is designed to block out all other wavelengths of light, so that views of nebulas are optimized. It also increases contrast through selective filtration. The filter is made from high-grade glass, with dichroic interference and antireflection coatings.
One of the benefits of using an OIII filter is that it can be used with all 2-inch eyepieces. It is also useful at light polluted sites, as it increases the contrast between nebula and night sky, not brightening the nebula.
The 2 OIII filter is also great for astrophotography. It enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions. The filter allows just for the Double Ionized Oxygen lines between 4959nm to 5007nm to pass through at 90%.
- The O-III filter completely blocks virtually all other visible wavelengths of light so views of nebulas are optimized;increases contrast through selective filtration-Anti-reflection coated to prevent glaring and ghosting
- The filter made from high-grade glass with dichroic interference and antireflection coatings;not only useful at light-polluted sites; the contrast is also increased at dark sky sites;it can be used with all 2" eyepieces
- Narrowband filter do not eliminate the effects of light pollution or increase the object’s brightness;in many cases, they increase the contrast between nebula and night sky, not brightening the nebula
- The 2" O-III filter useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming. Allowing just for the Double Ionized Oxygen lines between 495.9nm to 500.7nm to pass through at 90%
- Astrophotographic;The filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; 2" filter allows high-contrast imaging even in areas with strong light pollution
2. SVBONY Telescope Filter 2 inches CLS Filter City Light Pollution Reduction Filter Broadband Filter Suitable for Deep Sky Visual Astronomical Photography
City light pollution can be a real problem for anyone trying to do deep sky visual astronomy. It can be very difficult to see anything beyond the bright city lights. There are now filters available that can help reduce the amount of city light pollution. SVBONY has a 2-inch CLS filter that is designed to do just that.
The CLS filter is made with electron beam gun evaporation with ionassisted deposition coating technology. This makes the filter durable and resistant to scratching. It also guarantees stability on the central wavelength, so there is no deviation affected by temperature change.
The filter also features a planetary rotation system that offers precision and homogeneity of the coatings. This ensures high transmission of the pass band and optical density of the off-band. In addition, the filter has a 90 transmission of the main nebula emission lines, such as Ha 656nm, OIII 496nm, 500nm, and SII 672nm. It also has a 01 transmission of the off-bands, specifically the major emission lines of artificial light pollutions, such as Na 589nm, Hg 435nm, and 578nm.
This filter is suitable for color CCD cameras and unmodified DSLR cameras. It can be used to improve the contrast of shooting targets when used with urban optical filters.
