I currently have an ultra high contrast filter - Zhumell High Performance UHC - and have had some luck seeing additional features in larger objects while using it. I was thinking about purchasing an Oxygen-III filter also, but wonder just how different is the O-III compared to the UHC? Is it worth the money to have both in my filter collection? My scope is only a 130mm, and I would love to see additional details while finding and viewing DSOs such as Dumbbell and Ring nebulae, see more details in Eagle, Trifid, etc. It would be awesome to find something that would also enhance galaxies too (M31, M33 etc.). Does anyone know if an O-III filter will perform better than my current UHC filter?
Hi, As i may be looking to purchase an O-III or a UHC filter sometime in the future, I've a question thats been bugging me for a while. By picking up a 2" filter, would I also be able to use it with 1.25" EP's if I unscrew the lens of my 2x Barlow and replace it with the filter? Do they fit and are they the same thread pitch? I'd guess I'd be using my 20mm and 32mm EP's with the filters, but they are 1,25 and 2" respectively and I'm not going to buy the same filter in two different sizes. Thanks
Hi I want to improve my imaging of DSOs (I struggle a lot with LP) - particularly the Veil. But the price of O-III filters looks pretty steep to me. Except this one: http://www.365astronomy.com/SkyWatcher-O-III-Filter-2.html Would that be any help to me? Steve
