Playback PEM corrections


Chris Spratt
 

If you "train" the PEM at 1x or .5x what speed should you set the
keypad at when playing back the PEM? I usually have my speed set at
12x and leave it there for the observing once set. Does this setting
compromise the PEM playback?


 

Chris,
You don't need PEM unless you are doing manually guided astrophotography or
CCD work. There is no other reason to turn it on. You can put the button
rate anywhere. PEM playback is independent of the button rate. While
manually guiding, you would naturally want 1x or slower button rate.
