Guys, I want to be a DSO astrophotographer. Actually, I decided to buy a 150P-DS and HEQ5. But some advanced guys said I can buy a refractor like William Optics with Sky Adventure mount. So, I can buy the telescope and mount both for HEQ5 price. Also, William Optics' refractors are perfect. But, they show wide field and I hesisate about it. Also, I don't want to use guiding -because my computer doesn't have a battery, so I can't use it outside- Can Star Adventure track the stars without a guide scope? The Zenithstar 73 is about 3 kg.

Is guide scope very necessary for a beginner? Can I take good photos without a guide scope? With a 200p-ds HEQ5?

Yes, I will buy the 150PDS or 200PDS with HEQ5. I have new questions: Is EQ5, good for tracking? HEQ5 is too expensive... And, what is the ideal exposure time for astrophotography? For example, is 1 hour exposure for Andromeda Galaxy good? Or, is it unnecessary?

Could this be a problem with this telescopes? Need accessories? sorry for my teribble english...

Sometimes, I see people who can't focus their telescope. Also, there are problems about focusing the camera. Why? Skywatcher 150 or 200P-DS and CANON EOS 550D works together good

I want to observe and take photos of planets and DSO. I'm thinking of buying a Skywatcher 150P-DS. I will not do astrophotography professionaly. Is EQ5 usefull?
