(IAAC) re: Light Pollution Filters



Our 33-Doubles group has had a lot of discussion this summer about 
using these filters, especially the O-III filter, to split tight 
pairs with large magnitude differences, such as Antares. A number of 
group members were able to use these to help in splitting this pair, 
which was part of our summer double project involving observing 
doubles in Scorpius and Cygnus.
