Hi,

I used to moderate this forum last decade, but then took a long hiatus from astrophotography.  

Recently I mounted a Bausch & Lomb 24” f/6.0 aerial reconnaissance lens on my telescope mount, and shot some 4x5 Provia 100F.  The film expired in 2005 but has been kept in the freezer and is still good as new.  I don't think the jpeg compression of the scans does the image justice, but the TIF is too large to upload.smile
