Re: (IAAC) New
Hello Bill,
There is lots to see from anywhere. The first thing you need to (
if you haven't done it already ) is get a good star chart or
software like Redshift3. This will give you the locations to many
DS objects.
As far as eye pieces go I would suggest that you only need one
more, to go with the scope that you currently have, to bring you
up to about 120x to 150x any thing higher than that and the
quality of your image will start to degrade.
