Re: [APML]: Solar Images Show Ghosts? Help!

<< Hi Everyone,
 
 I've been practicing my sequence and routine for the Feb. 26th Solar
 Eclipse and just got back a roll of Kodachrome 64 slides tonight and have a
 problem with "ghosting" in the longer exposures.
 
 First, let me introduce my setup and give a more thorough description of
 the problem.
 
 Here's my setup:
 
 * 70mm f/6.4 (480mm f.l.) TeleVue Pronto scope working at f/7.4
 * TeleVue Field Flattener optic (changes scope to 520mm at f/7.4)
 * Bogen Tripod and head, i.e. no tracking
 * Thousand Oaks Optical ND5 solar filter
 * Nikormat camera and Nikon T-Ring
 * Kodachrome 64 slide film >>

Try tilting the solar filter rather than putting it on parallel to the 
objective lens.  This sometimes helps eliminate reflections.
