Subject: Re: autoguiding primer?

Right. Sorry about that. OK. Got all set up. Got a bright star on the monitor, made 

adjustments like 4x4 binning and black point. Focused pretty well. All seemed fine until I 

tried to calibrate. The message I get is something like: "No motion detected. Problem with 

USB, GPUSB or motors not working."

The sticky buttons work, or a least two of them - Up and Left (or was it Right?) So I am 

confused by the message. I mean the sticky buttons wouldn't work if there were a 

connection problem, right? But then, all four should work instead of just two. hmm

My setup:

ASGT 9.25/ Firewire webcam/ AstroIIDC 3.0/ iMac 500mhz/OS10.3/GPUSB using USB port 

on the mac to Autoguide port on the mount. 

not imaging anything right now, just learning to guide. Thanks for any tips

All set to go with my orion short tube 80 now mounted on my

I'm looking for a step by step autoguiding primer of sorts. I have  

Milton's instructions of

course but I got stuck at calibration. Will likely get stuck again  

so I thought I would ask.

Hoping there is something out there that can get me unstuck - even  

if it is not written

specifically for Astro II DC. Perhaps a guide with some general  

principles of autoguiding

that have been helpful to folks using Astro IIDC.

Can you clarify what you mean by "but I got stuck at calibration"?

As to a general guide, here is two links to lists of things to check  

before attempting guiding.

The first is by Darryl Robertson creator Equinox and is on the  

Equinox list:

and the second link is some additions I added that are more Astro  

IIDC specific:

Points 12, 13 and 14 from my list are very important, as is having  

good polar alignment.
