I live in low/mod LP area. For viewing, what LP filter should I buy first?

Hi Plium12.Welcome! When I was searching whether to flock,
baffle,{a 8" tube} or both, I came across a guy who showed
pictures of before and after he flocked his refractor. It was like night and day. He said that it gave 25% to 30%
more contrast. He also said that he only occationally uses
his LPF now. I've been reading that orthos also give more contrast and brighter views than wide fields.
In the refractor forum under "semi apo or baader fringe killer" John said that he had been testing the Astro Hutech
Idas LPS2 filiter for LP and he said that he liked it.
When I e-mailed him later he said thatit is subtle but it does help. Iv'e flocked my refractor and bought some Orthos but haven't been able to use them yet because of the weather.

I Just don't have the time,and exspecially the RV.LOL
The weather will be bad for another 4 days then I'll let you know just how great my improvements are.
I tried to download some before and after pictures of my flocked tube but the files are to big. If you want to see
reality send me a private e-mail and I will send you some pictures.
Clear Skies,
De Lorme

A light pollution filter is somewhat of a misnomer in that the good ones (which are actually narrow-band filters): OIII and UHC filters are useful everywhere. Even in the middle of the desert, the likes of the veil nebula will look much nicer if you pop in an OIII filter.
