Have you ever used palm softwares like Planetarium?
You can in fact connect your Meade Autostar (497) to the Palm PDA. Once do that you can tap on the PDA screen and direct your telescope to find any objects shown on the chart.
I have a cable which connects Autostar to Sony Clie PDA. It is built by me and it works for Clie S-series (i.e. those models with 13 pins in the connection port). I changed my PDA and so do not need this anymore.
Ask for $20 include shipping. Paypal preferred.
Money back guranteed if not working.
If you need a similar cable for your Palm PDA, I can also build one for you for $20. E-mail me.
