Subject:	PEC training

Just got my scope back from Dr. Clay. What a great guy and great
service. He suggested that since I added my AT66 and telrad to my scope
that I have to do PEC training. I never did this, and just don't what to
mess things up.  Here is what meade says to do in their manual:

1.     Select "PEC Train" from the Smart Drive 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 displays a count of the 150 positions of the >
worm gear. When > > the count reaches 150, one cycle is complete. A full
cycle takes about > 12 minutes. > > 3. Press MODE to exit.

Is there anything that I am missing? In step 2 it asks to use the arrow
keys to keep the star centered. Do I have to look into the eyepiece for
the next 15 minutes to do this? Also if I use the DSI camera to do this
does the mount have to be connected to the computer for guiding or can I
just use it unguided???? Thanks for your help one more time! I owe you
one!

That's pretty much the procedure... yes, you need to continuously
guide the scope during the procedure, but you can have the camera do
it for you.   If you're expecting the camera to handle the guiding/centering
during the training, it does have to be talking
Camera->(usb)->PC->(serial)->Autostar.

You can improve the PEC performance by doing PEC Update cycles
after the Training. They're just like Training, except that the
new data is averaged in to the old data to smooth out the "noise".

Some folks find that the tracking rate slows down after doing a PEC Train
(and then having PEC engaged).  Setup>Telescope>TrackingRate>Custom

For the PEC data to remain in sync with the worm angle, you -must-
PARK the scope at the end of every session.  As long as you do that,
you won't have to retrain.   You can unclamp the clamps and remove
the OTA without losing the PEC sync, as long as you Utilites/PARK.

If you'd like to -see- your PEC data, you can use Andrew Johansen's
PEC Editor from http://members.optusnet.com.au/johansea

have fun

Subject:	Autostar #494

Mike, first let me say I really find the Mighty ETX site very useful.  I
am a newbie but I am learning fast.  I purchased the ETX 80 BB and have
recently purchased the DSI Pro with filters to begin imaging.  The ETX
80 BB came with the Autostar #494.  Can the 494 be used with the ETX 80
and DSI properly?  All the information I find says the serial cable goes
from the computer to the Autostar ( 494 does not have a port to plug
into).  Do I plug my serial cable into the AUX port on the telescope and
to the computer?

Mike here: The DSI and LPI imagers work with the #497 AutoStar, not the #494. You could still use the DSI for imaging but without the AutoStar connectivity.

And:

Mike, I have found instructions on how to use the 494.

506CableSet.pdf Let me know if you see any problems here please.

Mike here: With the #506 serial cable (which is different than the #505 cable that comes with the DSI) you CAN control the AutoStar #494 from a computer. However, the DSI software requires a #497 AutoStar.
