Hanora,
Both the 6 & 8 inch Dobs are fine choices and are often said to represent the best value for money in the telescope market. Normally the 6 inch Dobs are F8 whilst the 8 inch Dobs are F6; so they both have the same focal length. Effectively this means the optical tubes for both scopes are much the same length, although the 6 inch will be lighter and so will its base. However, most working-age men will find the 8 inch light enough to move relatively easily.
The 8 inch telescope will collect more light, however, the 6 inch scope will work well with more eyepieces (and cheaper EPs) than the 8 inch. Also an optical defect called coma is much less obvious at F8 than F6. So there really are some good arguments for either scope.
Whatever U buy, it will be a fine choice, so enjoy the journey. This is a passion that can last a lifetime!
