I'm hoping to be getting the orion skyquest xt6 and I know that it has no tracking system or motor, and that its not necessarily meant for astrophotography. But I still have seem some nice images of the moon and some planets with it. I know that I could get no more than 5ish second exposures without it being a blur. ( correct me if I'm wrong on that...). Do you think it would be possible to maybe photograph brighter deep sky objects with it? Such as the Orion Nebula or andromeda galaxy? And what about star clusters- I assume some of those are a bit easier. The main thing I want to know though is ill be able to get a non-blurry picture with some color? (Especially for nebula)

I know sky conditions are a huge factor, and where I live does have a lot of sky pollution. My goal is to view most/all of the Messier objects, and hopefully photograph a few.

Thanks

One way scientists discover exoplanets is by transits of a planet in front of its star. Is it possible these aren't explanets at all but instead a wandering planet passing in front of the star, which is in fact not even close to the star? Or when detecting these exoplanets do they watch it orbit more than once? Which would rule out a wandering planet...
