Hi;

 

I'm looking at picking up a used 18" Webster Dob. I have never collimated a Newtonian. Any thoughts on how the Webster system works in terms of ease of collimation, as compared to other manufacturers?

Any other points worth noting in inspecting a Webster Dob?

 

Thx

No personal knowledge of Webster scopes, but they have a forum and FAQ at their website

I don’t can’t imagine that collimating a Webster would’ve very different than any other similar dob. Don’t be intimidated. Also be open to getting good tools. I’m guessing most Webster’s are sub f/5 so good collimation is critical to good views. You’ll likely want a paracorr
