If your DOB and low-mag eyepiece gives you a wide field of view (FOV), it's not too difficult to track LEO objects. I have a 6 inch (150 mm) f8 Dob. With a 35mm eyepiece I get a 1.4 deg FOV. This makes star hopping pretty easy. Of course it's at its best when timing Superbird A. > Take a look at meade or celestron offers > > http://www.meade.com > http://www.celestron.com Don't forget Discovery and Orion at http://www.discovery-telescopes.com http://www.telescope.com Orion's XT dobs were rated best overall in a Sky and Telescope review of 8" (200 mm) dobs. Discovery and Meade' rating were very good too. http://www.skypub.com/resources/testreports/telescopes/0001sixdobs.html When you budget your expenses allow for a 2x Barlow, an additional eyepiece (for the wide FOV) and (particularly if you live in Canada or northern USA) a solar filter. There will be a partial solar eclipse on Christmas Morning. Also - much of the telescope discussion has been covered in the recent past. Go to: http://www2.satellite.eu.org/seesat/seesatindex.html and do a "Goggle" search on the word "telescope". Before the scope arrives practice making plots suitable for a telescope obs. I generally find a spot no more than 3 deg from a bright star and wait for the object pass through my FOV. The plots themselves cover about 5 deg of azimuth and 4 deg of elevation with stars to mag 13 plotted.
