Re: (IAAC) re: Light Pollution Filters



I have used my Lumicon O-III and Deep Sky filters succssfully for double
star observing as well and have kept records of which stars were
separated by this method. I guess the next step would be to relate the
spectra of the stars involved to the filter used to see why some filters
work in this application.
I started doing this because I left my DSF in by mistake one day and
after a while figured out what was going on (yo...green stars).
Also I have found the DSF to be useful for Jupiter and regularly cycle
through the DSF along with the 81A when routinely observing Jupiter. PJT
