5 CommentsWhat type of light pollution filter should I get for my telescope?
Question by shish2kabob: What type of light pollution filter should I get for my telescope?
I have an 8 incj dobsonian reflector telescope and live in an area close to a city so at times there can be a bit of light pollution. I want to get a light pollution filter to view nebula more clearly, emission nebula to be specific. I read reviews on filters called narrow banded filters and OIII filters. Wat is the difference between these types of filters and which one should I buy? Please let me know if any information is further needed

Answer by GeoffG
Narrow band filters like the Lumicon UHC and Orion UltraBlock are the best all-around choice, since they block most of the bad light and pass the main nebula bands. The OIII has an even narrower band pass, so needs a larger aperture to function well.

nebula filters are like this

for those filter fits into the lense(eyepiece), they are bad.
the good nebula filters has to be the same size of ur telescope( the diameter in inchs or whatever ) for the aperture,
aperture is the front of the canon where lights from outer space goes in.

Q&A: Anyone know of a really good light pollution filter for a meade telescope?
Question by biker chick: Anyone know of a really good light pollution filter for a meade telescope?
I live in the UK and have a meade EX90. I love my telescope but live 15 miles away from a city and its very light polluted, I have used a couple of filters but I was wondering if anyone would recommend a light pollution filter. I do want to eventually want to work my way up to get a 8- 10 inch meade but I do feel will still have light pollution problems with a bigger telescope. Can anyone recommend anything?

the place to start is a broadband nebula filter, which everybody should have anyway.
narrowband filters are a bad choice for a little scope like yours. since they pass so little light, you need lots of light to start with to be able to see anything. a narrowband o3 filter does wonders on my 18″ dob, but in my 5″ apo i might as well have left the lens cap on.
