The Keyspan USA-19HS can be found for about $32 or less these days,
even from Dell and Amazon (where free shipping may apply)...

I use StarryNightPro v4.5 with my Keyspan, and it works
quite happily... on my Windows XP box.

have fun

It's been a while, but I want to get back into this astronomy thing with
my ET-90 PE.  I would like to start controlling it with my Mac......I
have a MacBook Pro 17" running OS 10.5.2, with 4 GB of RAM, and, if
possible, I'd like to control the ETX using my Starry Night Pro (Version
6.2.3) software.  What's been your experience with the Keyspan high
speed adapter, or are there less expensive options.  Is there anything
else I need to complete the connection?  I'll most likely buy what I soldering skills are less than stellar.

I know this has been covered before, but a search of your web site
mostly showed earlier (2001  2004) solutions, and I want to make sure
what I get will work with my system.

Mike here: My Keyspan Twin Serial USB adapter works fine on my MacBook Pro with Mac OS X 10.5.2. You will also need a #505 serial cable to connect to the AutoStar. It is easy to make using the instructions on the Helpful Information: AutoStar Info page.


Thanks for the quick response.  Do you know of anyone who's used that
with Starry Night Pro?

Mike here: I don't recall anyone mentioning that but I'm sure there are users who have.
