No Problems....once you make the purchase you will bring on cloudy skies in your city for a week - it's just what happens when you buy new gear!
No, getting the scope and finderscope pointing to the same spot is just the alignment of the 2 - this can be done during the day on any reasonably distant object (be very careful of the sun!)
Collimation is aligning the primary and secondary mirrors to ensure you get the best views at the eyepiece. Solid tube dobs hold their collimation reasonably well so you shouldn't have to do it every time and being a little out of collimation is not the end of the world.
I think many people user a laser collimator and some do a final check with a cheshire one but I'm not an expert.
I think andy's shot glass tutorial might help -

Would I need to get a collimator as well? If so, which one will be good? The reason I ask is because I have read a few places that Dobsons lose their collimation quite a bit.
BTW when you say collimating a Dobson, does it mean making sure the finderscope and the dobson are looking at the same place? |
