Optimising your GSO dobsonian.
So you have bought yourself a GSO dobsonian telescope.
Congratulations on purchasing what is in the opinion of many the best value scope on the Australian market today !
Whilst being cheap, the GSO dob has been designed and built with some compromises to keep the price down. The good news is that those compromises are not in the basic optical components and the scope can be greatly improved upon for little cost.
