Product Description
SV115 O-III telescope filter suitable for visual observation on most emission nebulae, planetary nebulae and supernova remnants. Bright nebulae such as the M42 Orion Nebula can be viewed more clearly using SV115 narrowband filter in conditions of severe light pollution.
Using narrowband filter can increases the contrast between nebulae and the night sky, rather than increasing the brightness of an object or removing the effects of light pollution.
18nm Narrowband OIII Filter
Narrowband OIII filter is designed for nebula observation allowing 18nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, 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 (i.e. skyglow).
The SV115 narrowband filter can be used with a variety of accessories such as astronomical cameras, focus reducers and eyepieces to achieve good seeing in both clear and dark observation conditions.
Strong and Sturdy
Made of quality materials, the threads are strong and durable, not easy to loosen, and can be used for a long time.
Ouality Optical Glass
SV115 O-III filter made from high-grade glass with dichroic interference and antireflection coatings.
SV115 filter comes with a plastic case with high pressure EVA case lining, protect the filter from damage.

Exactly what I would expect for the price. I'm only a novice astronomer so I can't give a professional opinion. I can say that it does improve my view when star gazing and looking for Galaxies or Nebulas. Well worth the money spent

Some folks shy away from 1.25 oiii's but the key is exit pupil...on a lower power eyepiece this one is surprisingly good.

A well made filter that that really tones the light down in the light polluted skies. Excellent value.

I purchased both 1.25 and 2" filters for use on a 10" Meade. Both size filters make the image barely there as it darkens more than filters. The 2" at least is a little usable as it allows more light. I even used it to view the bright Jupiter and all it did was turn Jupiter a very dark blue.I do not recommend.

Nebulas really pop with this filter great for visual observing or imaging . Does a great job at filtering out light pollution also grab it on sale

I went from wondering if there was really an owl nebula there to being able to clearly define the nebula straight on in sub par skies. When using averted vision, I could occasionally make out the "eyes" in my 10" dob. Filter offers substantial improvement for cost.

The 2 inch Svbony UHC and OIII filters would tighten in the Orion Q70 eyepieces. I would guess the thread tolerances for both manufactures are at their limits in opposite directions. I did notice the threads on the Svbony 2" filters are shorter than the threads on Orion 2" filters I'll be returning the OIII filter, UHC is past the return date. The 1.25 Svbony filters work fine with the 1.25 Orion and ES eyepieces that is have.
