Old Lumicon Ha filter
Hi everyone. Well its time to get back into harness which was helped by attending a decreased estate sale.
The only item of interest was a Ha filter made by Lumicon back in the 1980s. This filter looks like it is only deep red coloured glass without any reflective coatings. There are no labels or markings except "H-Alpha PASS Filter - LUMICON".
I bought it as I would like to start doing some Ha astro imaging. Anyone here with a modern Lumicon Ha filter version, and if so, does yours have reflective coatings? (Perhaps the one I bought is obsolete technology.) Regards.
