67FL F3.8 Astrograph

1st lot of 67FL objective is coming up in Japan. As mentioned several time, these are Canon-made fluorite optics. As far as I know, Canon is the sole producer who is continuously and commercially polishing fluorite optics in the world.


67f3867FL F3.8 Astrograph (objective is prototype)

2567 + 7025 + 2 x 7050 + 7801 + FTF-BORG + FTF-M57 + 7352 + 7885 + 5005 + Canon

Unlike 7870(0.7x reducer), this system allows to use longer main tube (125mm total). So it’s better for overall weight balance. If M57 camera rotator isn’t used, we can replace these 3 tubes with + 7136. This system will be added as [part # B06738] in astrograph package. This is fastest speed among BORG astrograph family.
