I wanted to ask about the filter curve of the filters (mainly the iDK 20" at Hakos, but the others are welcome too for photometric purposes). Do you have the manufacturer and model of the filters (for example, Astrodon LRGB Gen2 E-series)?
If the manufacturer supplied a copy of the tested filter curve, would it be possible to share this ?
In any case, if I know the manufacturer and model I might be able to find approximate curves online, which already greatly help with photometric studies.
