The AC 90/600 telescope's optics are ideally suited to surveying wide fields of view in the night sky. For observing Open clusters, in particular, it works wonderfully!The 9 centimetre diameter objective lens collects enough light to observe a range of Messier objects. The Messier objects are star clusters, galaxies, planetary nebulae, and supernova remnants captured by the French astronomer Charles Messier (1730-1817) in his catalogue of 'nebulous objects'. Hunt down as many objects in Charles Messier's catalogue as you can!Of course, the planetary astronomy is also now open to you - observe the rings of Saturn and the moons of Jupiter! The relatively wide field of view of this telescope also makes it especially interesting for observing comets.
