27006 OIII 3nm Bandpass
Chroma’s OIII filters isolate the 500.7nm primary emission line of doubly ionized oxygen. After H-alpha, this is the next most common emission when imaging nebulae
27007 OIII 5nm Bandpass
Chroma’s OIII filters isolate the 500.7nm primary emission line of doubly ionized oxygen. After H-alpha, this is the next most common emission when imaging nebulae
27008 OIII 8nm Bandpass
Chroma’s OIII filters isolate the 500.7nm primary emission line of doubly ionized oxygen. After H-alpha, this is the next most common emission when imaging nebulae
27066 OIII 3nm Bandpass optimized for f/2.8-f/3.6
Chroma’s OIII filters isolate the 500.7nm primary emission line of doubly ionized oxygen. After H-alpha, this is the next most common emission when imaging nebulae. Chroma’s f/3.0 filters are designed to minimize spectral shift and hold their shape better in an f/3.0 beam.
