Looking at the specs of these two filters they seem to be almost duplicates. The prices for the 2" versions are even within $10 of each other. Does anyone have experience with them to comment on whether there are actual differences? I'm looking to get one for both visual and some EAA views of galaxies and other DSO, under light polluted skies. I already have the Optolong L-eHance, which is great for nebulae (I imaged the Horsehead with EAA under Bortle 7/8 skies). Any thoughts are highly welcomed.
