Review of Celestron Oxygen III filter
This is a great filter for viewing emission nebulae. This filter easily doubles the size and greatly increases contrast on several dozen nebulae. I would recommend this filter if you live in a light polluted area. The only con would be that it darkens the field somewhat so I recommend this filter for anyone using a 4" refractor/6" reflector or larger scope.
Pros: Brings several nebualae into view
Cons: Darkens field just a bit.
Narrow Band III filter
Filters the visible spectrum at 435 nano meters, I plan on using this filter with the Celestron Ultima Dou Eyepiece and DSLR camera, I just need 2 more to complete my RGB set SII and HA. I just wished, these filters were not so expensive. THe images I got with OIII was crisp and sharp with my SCT and Newtonian.
Pros:
- Fits eye pieces
- Just beautiful
Cons:
- Expensive filters
Best Used for:
- Astrophography
Would recommend: Yes
Great filter, great price
I was wanting to get an oIII filter
to catch great views, trouble was, they were all too expensive, and I was worried about quality, you know, cheaply made glass, cheaply coated optics, and anything else that would detract from a proper view of nebulae, which happen to be among my favorite targets.
Pros: easy to thread, works great, unobstructed view
Cons: none that I can think of really.
