Ive noticed when centering a guide star in the reticle eyepiece prior to
autoguider insertion, stars that appear to be the same brightness are
perceived to be quite different by the 201. Ive had stars I thought would
need only a 1 or 2 second exposure by the 201 end up with 6,8 or 10 second
exposure. Then Ive had what I thought was a star of equal brightness, end
up using 1 or 2 second exposures when it should have been 6 or 8 seconds. It
doesnt make sense. Can anyone shed any light on this subject?
Thanks in advance. Alan
