Hi Glenn.
This forum is a great source of information and one of the ways to find such information is with the forum search function.
We get a lot of newcommers to the forum asking which scope to buy and as often as not they are pointed towards the GS dob. The same questions have been asked and answered many times before on this forum and a search will yield answers to many questions. If not , there are many helpful knowledgable people here who can help
