Follow up on my recent lecture on Narrowband imaging

[Simon Lewis]

At my recent lecture I showed you an easy way into NB imaging using colour cameras and a variety of dual/triband filters.

A recent post on the Cloudy Nights forum caught my eye and thought I would share it with you.

Canadian Astrophotographer, Jim Thompson, has carried out quite a study on some of the filters I talked about inc some really great spectral measurements. What’s interesting is how some of these filters are marketed and their actual filter response!

All isn’t quite as it seems and its worthy of a read if your’re interested in buying one of these filters.

The full thread is at CN here:

I’ve also attached a PDF of the reviews he carried out for download:  Here

 

Kind regards

Simon
