Hi Erick (everyone)
I've used http://stores.ebay.com.au/BJOMEJAG-E...QQftidZ2QQtZkm
supplier in the U.S with great success, as have many members of my club.
Prices are significantly cheaper (even with postage) than OZ prices.
The filters work brilliantly.
Erick,
I've used my 2" UHC/0111 filter with great success on Eta Carinae, Orion Nebula etc, plus finding those elusive faint planetary nebulas. http://bjomejag.squarespace.com/ is his main site.
It will give you a great background to man.
