Hey everyone, I'm relatively new to the whole Telescope/Astrophotography world and I'm buying a William Optics Zenithstar 73 APO for DSLR astrophotography soon. I'm having some difficulties choosing the right/most affordable EQ Mount. I'm thinking of buying an EQ3 Pro which comes with a Go-To system. It apparently has a 5Kg weight capacity for imaging and the Zenithstar weighs about 2.80Kg, and with a camera that weighs about 480 grams I'm left with 1.7Kg to spare (I don't intend to get a guiding scope yet). Is this a good choice? I've read that the EQ3 is not that good, but I don't intend to do anything too serious with my astrophotography and will be mostly on the road so the less bulky mount would be a life saver.
