Steve, I just got back some photos taken Sun. nite through my 10" lx200 on
hypered
PPF 400 using the Lumicon Deep Sky Filter. This was through the GEG at
f/6.6.
I don't have a web-site yet; I hope to soon. I got very good red response
with well defined dust lanes. I had a fair amount of blue response but I
have seen photos with much more. I'm thinking that the ppf 400 is not the
best film for recording blue reflection nebulas, so I can't help but think
film might have made some difference.
