Astronomik UHC-E Filter

Astronomik UHC-E Filter – This filter was designed for the visual observation of emission and planetary nebulae with (mainly) smaller scopes, but also works well for imaging these objects if used with an IR block. The IR block can be inbuilt, as with a DSLR, or in combination. The Astronomik L3 type luminance filter gives particularly good results and colour balance. Price includes delivery.
