OIII Filter
Hi Solanum,
Can not recommend the Astronomic OIII highly enough. I regularly use it in the 16" F4.5 scope in my observatory and in my 12" (highly modified) Lightbridge when observing with Kevnool out in the scrub.
The Keyhole through my 31mm Nagler with the OIII in is amazing, it virtually fills the very wide field of view.
Their are many objects that the OIII seems to work well with, NGC2736 Herschells Ray, NGC3199 The Southern Crescent, IC 3199 The Runing Chicken, NGC 2359 Thors Helmet and IC 2944 to name a few.
I also use an 1 1/4 OIII Astronomic in my 14mm Meade UW & 9mm Nagler to great effect on many PN's and on the less extended nebs.
I also have a 1 1/4 Meade Nebular filter which is a broadband filter and find that I really dont use it much at all since the arrival of the OIII's.
The 1 1/4 filters work well in a filter wheel.
