Is this the scope that DSE has?
PowerSeeker 127EQ
I looked at the DSE siet and could only find the
Star tracker 127 which looks quite similar.
Regarding these scopes, I honestly don't think they will be too bad. They are reflecting telescopes of 5" aperture, and they don't appear to have a built in lens to increase focal length. I don't know how good the equatorial mount will be, and that's where the dobsonian design theory comes into play. With a dobsonian, you won't have the risk of a wobbly mount because of it's simplistic design. Dobsonians will be quicker to set up, just sit it on a flat area of ground. Both equatorial and dobsonian telescopes are equal with regards to collimation - they are both newtonian reflector telescopes. The advantages of a dob become more apparent at larger sizes. You can get a 12" dob for under a grand, where if you wanted an equatorial mounted reflector telescope of the same aperture on a mount that "isn't wobbly" you will be looking at double or triple that cost.
