Recommendation for a nebula filter

[[1ponders]]

Save me seaching, what recommendation for a good nebula filter for use with a 35mm Panoptic?

Horse for course, of course, but all I have is an O3, Baader, in 2" as well.

cheers Gary. TFT

I should say this is for visual observing...yes that's right you heard me right. :lol: I guess I'm tossing up between the Lumicon UHC and the Lumicon Deepsky filter. (2" ) It would be used for public viewing through a 12" Dob

Hi Paul,

If you are only going to own "one" filter for visual deep sky observing, the DGM Optics NPB filter is the best choice IMO.

I also have the 2" Astronomiks UHC, OIII and H-Beta filters and the 2" Lumicon UHC filter. There are certain individual targets where each of these filters will outdo the DGM NPB. However, the DGM NPB provides some improvement on the largest number and on the widest range of targets. The DGM NPB is classed as a narrowband or UHC filter but it has very narrow passes near the OIII lines and is essentially a hybrid OIII/UHC filter. In addition to that it is very reasonably priced.

FWIW I don't have a 35mm Pan, but I do use it in the 31mm Nagler.

If you wanted to buy "two" filters then I would recommend an OIII and a UHC from either Astronomiks or Lumicon. For the one filter DSO observer, the DGM NPB is very hard to beat.

Cheers,
John B

Any old will do for public viewing :whistle: but if you want to eekk out every last photon you can't go past an AstronomiK brand. I did an exhaustive test with Graham Longs UHC Lumi and the Astronomik beat it hands down! I think Bintel are agents. When you get the 2" variety I'll have to have ( as Ron says) a shooffty???:P

Thanks for your input guys. It's a balancing act (volunteer observatory) of price and performance. I think the Lumicon might be the way to go for me. Thanks again.

This is sound advice!

The DGM NPB is a very good filter...

Not sure if it is still available but there was a astronomik 2" UHC filter in
the trade section going for $155.00!!! now that cheap. I would of grabbed
it myself except I blew my budget on a couple of EP's.

Cheers

I have 3 Lumicon filters - DS, UHC and OIII. I mainly use the UHC. The DS is good if you have light pollution, the OIII usually filters out too much light.

Thinking of leaving the dark side of the force and coming back towards the light Paul ?;)

I bought a 2 " orion ultrablock last year and have been pretty happy with it

I had a lumicon uhc and they both seem to do a similar job though at the time I bought
them the ultrablock was half the price
If you can wait a while they often run a summer sale in a few months.
