The Palomar has a corrector plate.
From:
http://www.cr.nps.gov/history/online_books/butowsky5/astro4f.htm
The corrector plate at the upper end of the tube is 49.75 inches in
diameter. The 48-inch telescope, at an optical speed of f/2.5 covers
an angular field of 7 degrees. The telescope is guided by two 10-inch
refractors attached on each side of the tube.
