It would be helpful if you could explain (a) what settings are needed in Sky Safari, and (b) what specific settings you need to enter in AlpacaScope (including, where applicable, port numbers and ip addresses). Also, I am confused by the fact that your post mentions Windows (I assume that the Windows PC runs the telescope mount) but your github page also mentions Mac OS and, further, has a number of files for various versions of Linux. Without some further explanation or documentation, it isn’t readily clear to me how (in terms of the practical steps required) you would use this application.
I'm going to answer the questions in the order of operations, not the order you asked:
b) Do what you normally do to get your mount & ASCOM up and running. Then install/configure/start ASCOM Remote. ASCOM Remote exposes the ASCOM API as the new Alpaca API. The first time you run ASCOM Remote, you will need to go into the Settings and enable your telescope mount.
Then, most people will install / run AlpacaScope on the same computer as ASCOM. As for IP addresses / Ports- the defaults should work 99% of the time. If you're one of the 1% then either ASCOM Remote isn't running, is using non-standard settings or is running on a PC on a remote network from ASCOM Remote.
The only thing you really should worry about are Telescope Protocol and Mount Type. The Telescope Protocol is how AlapcaScope communicates with SkySafari, NOT the telescope mount! I support both Celestron NexStar/Advanced GT and Meade LX200 GPS in SkySafari. If you're using something other than SkySafari, pick an option that your software supports.
If using Celestron NexStar, then you can choose the mount type to be reported to the SkySafari/etc.
a) Configure SkySafari like you were using a SkyFi. Select "Auto-Detect SkyFi" and "Celestron NexStar/Advanced GT" as your telescope (assuming you selected NexStar in AlpacaScope). You can run SkySafari on the same computer or a different computer/iOS/Andriod device. If running on the same PC, SkySafari will report it was not able to discover the SkyFi- that's OK, it will connect anyways. If using another device for SkySafari, then it should auto-populate the IP address of the computer running AlpacaScope.
As for why there are versions for Mac/Linux/Windows: The answer is that advanced users (say people with remote observatories) who which to control their mount remotely may find supporting other platforms useful. Also, I do all my development on a Mac and because AlpacaScope is written in a programming language called "Go", support for all these operating systems is easy.
Anyways, there is more docs on the readme: https://github.com/s...tic/alpacascope
