The articles by Kreimer,on his 4 by 5 cold camera and guiding head appear 
in the Observers section of S&T Dec. 1965 pp384 and Aug. '66 pp106 (which 
has a good photo of his guiding head.He used a microscope head guiding at 
1200X,with the guide star behind a tiny metal disc cemented onto the 
cross hairs.The edge of the field was used,as he states the mirror's off 
axis coma produced seagull star images.
Hopes this helps Jack.
