Description

I captured this image of the Crater trio Cyrillus, Theophilus & Catharina last week in the early evening during daylight using a 610nm red long pass filter, just to see it this would give me any results that would have sufficient contrast, and if it was an option to begin with to use such a filter on my ASI462MC color camera. It seems that indeed this improves the contrast quite a bit by filtering out the predominant blue part of the spectrum that is present before sunset.

And usage of such long pass filter seems very well possible with this camera that has its highest sensitivity in the infrared wavelength spectrum. It is important however to equalize the R G & B histograms well in Firecapture so that they overlap.
