Can someone give me some advice about filters. I prefer to spend a bit extra to get quality filters first up so I don't have to spend more later to update.
1. Should I buy 2" or 1.25" size? I assume 2" is more versatile because I can use those with a 1.25" eyepiece with an adaptor, but I can't use a 1.25" filter with a 2" eyepiece.
2. Is there any difference between filters used for visual and astrophotography? I want to leave my options open so I can use the same filters for astro down the track.
3. Does anyone have experience with the Orion range of filters? I was wondering how they compare to the other brands on the market.
I plan to get to as many star parties around Newcastle/NSW as I can with my new scope. See you there.

Simple.
Don't buy any.
You will almost never use them.
The only time you might is looking at Mars when an orange or red filter increases contrast. Even then I just used an old photographic filter and rested it on the eyepiece.
