Today - I just received my two 1.25" O-III filters I ordered through Robs eBay site, which now add to another 2" I bought from Rob at Omega through astronut. Great international service I'll say. The
TWO 1.2's landed at my door today for
US$88 including shipping. Not bad.
I tried the 2", mounted at the the base of my 2" extension tube in the 8" Newt the other night (with John "astronut"), and was pleasantly greeted with a great contrasty view of the Eta Carinae, Turantula and Orion nebulae. It certainly made a huge difference to the dark lane areas - as advertised. By mounting it to the extension tube I can use the same filter for 2" and 1.25" EP's as usual by merely swapping the adapter above it.
I bought two of the 1.25" so that I can use both at the same time on the bino-newt that is in the works.
I guess that the other filters mentioned might be better in some way - but my human frailties and eyesight will probably prevent me from getting any better value from them. For the price, these are great.
Thanks John - a great pickup!
