Optolong L-Enhance dual band filter

Dual band HA / OIII filter for colour CCD and CMOS cameras inc DSLR to allow narrowband imaging using colour cameras.

The bandwidths:

= 24 nm for OIII and H-beta

= 10 nm for Ha

2" thread fits most reducers/flatteners allows direct mounting on the optical path.

Used but perfect condition
