Baader U Filter  [Re-Mounted in 49mm Mount, Glass Reversed]

£350.00

Specially adapted 49mm Baader U 365nm UV passing filter. The filter passes only a band of UV from approx 320nm upto 380nm with a peak at 350nm, it has special coating that almost completely supresses any IR. In comparison to the two filter combinations [UG11+BG39], the Baader U lets about double the amount of  UV through, which allows hand held UV photography albeit at quite high ISO's. The filter glass has been reversed from the manufactures spec to reduce flare and reflections when used with a camera lens rather than a telescope. This Re-mounted Version is a reversed Baader U filter just remounted in a plain 49mm Mount. The pictorial photos are taken with one of these adapted filters. See the UV tutorial page for more information. [Please ask if you prefer the original 48mm version shown in the main photo]
