Dual-band, tri-band, quad-band nebula filters

Recommended Posts

Posted (edited)


I was trying to get more information on the rather new "nebula filters", and I thought it would be interesting to share my findings into a Google spreadsheet :)  

I haven't included filters with a broader band pass, like the IDAS LPS V4 or some of the CLS CCD filters, which I believe are a different kind.

Also, regarding the FWHM, it reflects what the manufacturer officially claims. In the case of the STC Duo, it's unclear and I've seen different versions (10 and 12nm, 80 and 90% transmission). So, take it with a grain of salt :) 

Hope that helps!


Here are the links to the manufacturer's website:
