Guest Tweedledum Posted September 16, 2014 Share Posted September 16, 2014 Hi Michael, Its not so much "is it any good for a 10" do"' but will it improve my viewing. It really depends what your targets are. You need to give us more info on what your interests are in the sky!. Link to comment Share on other sites More sharing options...
Doc Posted September 16, 2014 Share Posted September 16, 2014 Take a look at these sites: http://www.prairieastronomyclub.org/resources/by-dave-knisely/filter-performance-comparisons-for-some-common-nebulae/ http://www.prairieastronomyclub.org/resources/by-dave-knisely/useful-filters-for-viewing-deep-sky-objects/ The first one tells you which filter to use for which object. I find the O111 filter alot better then a UHC. Link to comment Share on other sites More sharing options...
Guest Tweedledum Posted September 16, 2014 Share Posted September 16, 2014 Doc, That is a great find. Worth pinning somewhere on the forum. Link to comment Share on other sites More sharing options...

Guest Tweedledum Posted September 16, 2014 Share Posted September 16, 2014 Not to me, concise & clear info. Link to comment Share on other sites More sharing options...
Tweedledee Posted September 16, 2014 Share Posted September 16, 2014 If you have some 2" eyepieces, get a 2" filter. You can usually fit them to a 2" to 1.25" adapter for use with smaller eyepieces. Those websites have been in my bookmarks for a while. Extremely useful info. Link to comment Share on other sites More sharing options...
Tweedledee Posted September 16, 2014 Share Posted September 16, 2014 In my opinion those filters are a useful addition to your kit but are no substitute for really dark skies. You will find much more expensive makes of filter that are probably only marginally better. Link to comment Share on other sites More sharing options...
Daz Type-R Posted September 16, 2014 Share Posted September 16, 2014 Pinned as requested in the observing section.... http://www.eastmidlandsstargazers.org.uk/topic/8655-filter-performance-comparisons-for-some-common-nebulae/ Link to comment Share on other sites More sharing options...
Guest MichaelDurban Posted September 16, 2014 Share Posted September 16, 2014 I have the full messier list with a run down of the appropriate filters was just checking...the price is quite low. I can't afford a O III yet. so o was thinking gettong this UHC Link to comment Share on other sites More sharing options...
Doc Posted September 16, 2014 Share Posted September 16, 2014 I would get the UHC first and see what improvements you see while observing then when you can afford it upgrade to the O111. Good thing about astro gear, you very rarely loose a lot of money on it especially if you buy and sell second hand. Link to comment Share on other sites More sharing options...
Guest MichaelDurban Posted September 16, 2014 Share Posted September 16, 2014 Yep...those were my thoughts exactly Mick. I was just stumped by the price, I know there are high quality filters such as Astronomik and 1000 Oaks, but this one (albeit GSO) is only GBP 15,- converted !

Doc Posted September 16, 2014 Share Posted September 16, 2014 You get what you pay for Michael. When I buy filters I try to get the Baader ones, I think they are a good buy compared to the Astronomik and 1000 oaks one. Link to comment Share on other sites More sharing options...
Guest MichaelDurban Posted September 16, 2014 Share Posted September 16, 2014 Yes.... I will try this filter and order it, which may take a while.. If it is bad...I can always write a cautionairy review. Link to comment Share on other sites More sharing options...
BAZ Posted September 16, 2014 Share Posted September 16, 2014 I have a Sky watcher OIII and a UHC filters, both Chinese like the GSO's and both do well for me. I would try different filters, as what might work for someone else may well work different for you. Link to comment Share on other sites More sharing options...
