Periodic Error Correction
If you wish to perform high-precision astrophotography, you may wish to "train" your
telescope in order to keep objects that you are imaging dead center in the telescope's
field of view during the photographic exposure. Periodic error correction (PEC) helps
to remove the slight perturbations from center that occur due to the mechanical
nature of a telescope. To perform this procedure, you need to use a high-power reti-
cle, such as the 9mm reticle (see
OPTIONAL ACCESSORIES
, pages 48 - 50). PEC
training is available for both drives.
Train Menu Option
Important Note:
The Train option overwrites any previous PEC data.
1. Select "Train" from the RA PEC menu (in the "Setup: Telescope" menu) and press
ENTER.
2. Look through the reticle. Use the Arrow keys to keep the star centered in the reticle
cross-hairs. Autostar II displays a count of the 64 positions of the worm gear. When
the count reaches 64, one cycle is complete. A full cycle takes about 2 minutes.
3. Select "Train" from the R.A. PEC menu (in the "Setup: Telescope" menu) and press
ENTER.
4. Press MODE to exit.
Update Menu Option
Use the Update option to further refine your training; it is recommended that you
update your original training two or three times when first using your telescope.
Update does not overwrite the data, but updates the training using information gath-
ered from both the last and the current training sessions. Press the MODE key to exit
from this option. If you wish to further refine your training, select this menu again and
repeat the procedure.
Erase Menu Option
Select this option to erase all PEC training data.
On and Off Menu Options
Select "On" when you want the telescope to use the training information. Select "Off"
when you do not want for the telescope to use the training information. Select "On" to
enable the Smart Drive.
