Hi all! I have a Celestron Nexstar 8SE telescope and I even bought the GPS unit for it! For some reason with deep space objects away from the immediate planets, I have trouble accurately centering the three stars during the alignment procedure and while near space objects such as the planets work well with the "GoTo" hand controller, the deep space objects always seem to be slightly off. Do you have any tips or hints on what I should do? Also, if the objects are slightly off, what is the best way to find the objects? Use a star map? I was hoping that with my GPS skysync unit my alignments would be completely on target. It is a little frustrating. All tips and hints would be highly appreciated.
In addition, I haven't been able to take it somewhere away from the night sky of the city yet, so I understand my viewing capabilities will be severely limited until I do so (even though I have an urban city filter). Anyhow, I can of course see the planets beautifully and even star clusters; but I have not been able to yet see galaxies or nebulae. What kind of deep-sky objects can I expect to see with my 8SE both in the city and then away from the city?
Thanks in advance for your input!
