Hi Bryan
We have a bakery in the main street that has far better pies than the Pie Shop. They're not open on Sundays but this is going way off topic. Did I mention the great pizza place in the main street too
I think your connection issue is something to do with the properties in device manager. I assume you're looking to connect LX90 to laptop wired ie no wifi unit? I drive my goto dob with the Orion wifi interface and it is the only way to go. Using Sky Safari Pro I can keep all my observations recorded. Don't do any astrophotography anymore. The observing side of things is so much more sociable not too mention completely hassle free. Plonk the dob down in the driveway and observing in a minute or two as dobby lives in the garage.
Shoot me the pm, I'll give you my address and you can bring your gear down and give it a whirl. Are you still a member of SASI (I'm not but still in contact via Facebook with most of the crew)?
