Hello Gianluca,

> For the first time I would like to use a Meade DSI for autoguiding
with PHD Guiding via Ascom platform. Is it a working setup?

Yes, I think so. But I haven't tested this setup myself. There are so
many different programs and autoguiders that I can's test them all
myself. If you have successfully tested a software that's not already
described on my website
http://www.astro-electronic.de/software.htm
or here
http://www.astro-electronic.de/relbox.htm
then please write a small report for my website.

> This should provide an excellent PEC teaching.

That's right. But on the other hand, if you have an autoguider you
don't need PEC. The autoguider will automatically correct the
periodic errors, and even better, it will also correct the non-
periodic errors :-)
