Revision as of 17:10, 13 October 2008
I'm a complete beginner what concerns telescopes and astronomy, so I thought that my experience about telescopes might be useful for other beginners. Therefore also, a lot what I write here is about what I think, I just discover all these things for myself, only for entertainment.

What can I see through it
I don't really have much idea what can I see through that telescope, but Charles Messier who made the catalog of 110 deep sky objects (galaxies, nebulae and star clusters) in 1780, had a telescope which may be equivalent to today's 3 inch telescope, so I should see all these objects at least somewhat. But of course the skies of Paris were not so light polluted at that time, when there were no electric lights yet, than the skies of the cities today. Indeed I have found that I cannot see as much as Messier did, in addition having by far not such experience of observing as Messier had. Hodierna [1] found 19 deep sky objects already in 1654, using only a Galileo telescope with 1 inch aperture, of which 12 were Messier objects and 7 of these (M31, M36, M37, M38, M42, M44 and M45) were in the northern constellations.
There is a review in Cloudy Nights of the Orion SpaceProbe 3 EQ [2] which has an equatorial mount, but is otherwise optically similar to this telescope. At least it shows that one is able to see with this telescope the colors of the Orion nebula. I though didn't succeed the see colors of the Orion Nebula in my conditions, but considering how bright the nebulosity is, it seems believable that one can see some colors even with the visibility one magnitude better than mine, which is even not so good visibility, and you don't even have to be in a rural area. So don't be discouraged, your visibility is most probably better than mine.
