yep doth scopes are produced in the smae factory using all the same gear... as Louie said I went out and bought the 12" GS but if you want to get into astrophotography buy something like the LX.... Motorising the DOB can get expensive......
Im sort of a NOOB but i can now pick out a few objects.... like the striped soccerball ....
Hope i've helped
