It is suitable for visual observation on most emission nebulae, planetary nebulae and supernova remnants. Additionally, you can use it with H-alpha and OIII narrowband filters (SHO Set) for tricolor CCD astrophotography.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBoth of the new SII and Ha filters from ZWO have a positive and negative side.  Telling the camera and telescope sides is very simple.
