fwm891 Posted January 12, 2018 Share Posted January 12, 2018 Being a 'tinkerer' I got to thinking that my Nikon adapter has a 48mm T thread and my 2 inch filters have a 48mm thread so I could have just threaded the filter onto the back of the flattener/reducer and the Nikon adapter to that but that would destroy the back spacing. So I decided to try taking the filter glass out of its holder to see if it would fit inside the Nikon adapter it does! and the adapter with the filter inside still fits onto the back of the flattener/reducer without effecting the reducer/camera spacing. So I can now use narrow band filters with my 0.79x reducer/flattener on the 115 EDT_APO for wider FoV's with the Nikon. Johnnyaardvark 1 Link to comment Share on other sites More sharing options...

fwm891 Posted January 16, 2018 Author Share Posted January 16, 2018 Update: One of my filteres was just too big to slide into the threaded section so taking the threaded ring out reveals a recess and back bevel to the threaded ring letting me drop the filter in behind the threaded ring. Not a quick filter change but if you have an LP filter or a dedicated Ha camera then this might be a more permanent option... tuckstar 1 Link to comment Share on other sites More sharing options...
