Ordering information
Mounted on a short-tube 80mm with 1.25" focuser:
The barlow insert should be adjusted so the magnification is double
that of a direct-projection setup. Moving the insert towards the film
plane will decrease magnification. After adjustment tighten the two
setscrews to securely hold the insert. The telescope will likely focus
at a different setting with the barlow included. If enough out-focus
can not be reached, additional spacers may be needed.
