I wanted to provide some information and tips in regards to using fluorescence on the Arcturus XT. First, I am posting a reference sheet to give you the excitation and emission properties of the Nikon filter cubes we sell. you may only have the red, green, and blue cubes if you purchased the standard fluorescence package, but also, you may have the UV and Triple Pass cubes if you decided to upgrade at some point. Nevertheless, also attached is a reference guide with tips on how to optimize fluorescence viewing on your Arcturus XT. Please feel free to comment if you have any questions, concerns, or more information to add.
