|Astronomik 1.25” H-alpha 12nm Narrowband CCD Filter |
I am moving to a larger filter so I am moving my filters to a new home. I was using this filter last week during the full moon to capture the Horsehead Nebula with good results.
The FWHm of 12nm is optimised for typical DSLR cameras with CMOS sensors and CCD cameras with a normal/high dark current: With these cameras the background signal in images taken from heavily light polluted sites is dominated by the dark current of the sensor, not by flux coming from light pollution.
