- Got a Telrad & no finder scope? Use your binoculars behind the
Telrad for magnification. Ast first, it’s a little tricky lining
up the binoculars with the Telrad, but with practice, it’s not
too difficult & will allow you to position the telrad on fainter
objects – Dave Scherping (original idea from Steve Bornemeier) -
At the start of an observing session, look at a star or planet
with the eyepiece outside the normal focal position. You can see
the turbulence crossing the image. If it is doing anything other
than going straight across you know you have a local seeing
problem that you need to take care of. – Martin Gaskell - The
eye is more sensitive to very dim, large, objects when they are
moving. Thus, the Horsehead is far easier to see if you gently
move the scope back and forth a few minutes of arc once every
two seconds or so. Let the image move, don’t try to follow it
with your eye. The brain seems to define faint edges best if
they are moving across the retina, constantly hitting new areas.
