I am also new to the world of scopes. I am surprised you haven’t had a reply as yet ,i am sure it wont be long before someone on here gives you the information you are wanting.
Regards to the GO-To i bought a Sky watcher 127 some weeks ago ,this being my first ever scope. It takes a bit to get to grips with the go-to handset and still after 3 weeks and only 4 nights of being able to use it. The advice i was given ,was to get a telescope that had a go -to as this would be idea for someone never used a scope before. I have managed to connect it to my computer and during the day test it with a program called stellarium. Good luck and i hope you get many replies
