Known errors and misprints in
ASTROPHOTOGRAPHY FOR THE AMATEUR
by Michael Covington
1991 edition


Last revised 1997 November 9


(Some of these errors have been corrected in some printings.)

OVERALL: Many black-and-white photographs are 
reproduced with excessive contrast and excessively 
dark backgrounds.  The color plates are well made
and are a better indication of how photographs
should look.

p. 27:  Picture is flipped left-right.

p. 57 last paragraph:  Despite advertising claims made
in the 1970s, Schmidt-Cassegrains do not cover an 
"exceptionally large field."  They have appreciable 
aberrations even 1 cm from center of field, which is why
collimation is critical.  However, they remain the most
compact and versatile telescopes, and I continue
to use them.

p. 111 top:  In some printings the two pictures are
reproduced with excessive contrast and look just alike.
The left-hand picture should have normal contrast but 
be slightly blurred; the right-hand picture should be 
a sharp image with a smeared effect superimposed on it.

pp. 124-126:  Many of these film recommendations are
out of date.  See  http://www.mindspring.com/~covington/astro
for updated film recommendations.
