Is the Celestron astromaster 130 EQ Model able to see nebulas and galaxies? If this telescope is not able to see nebulae, please suggest me the best one telescopes for nebulas.
The question isn't whether you can see deep-sky objects but how many. Given a reasonably dark observing site, the Orion nebula and the Andromeda galaxy are visible in 7x50 binoculars. A 130mm objective should be enough to see most of the nebulae and galaxies in the Messier catalogue. Once you get the hang of it, you may be able to see a few NGC objects too, but a bigger scope will show more of them.
