A 4.5″ reflector will get you there cheap - about $200. You might even find a 6″ in the clearance section of a good astonomical website. But get a good one - not Jason or Bushnell, and not the no-name brand cheapos on Ebay. Go with Orion, Celestron or Meade - in that order. A 4.5″ or 6″ “Starblaster” is a good option. You’ll see the rings on Saturn, Great Red Spot and bands on Jupiter, Polar cap on Mars, hundreds of craters on the moon. In Deep Space, you will not see any galaxies, but you will see nebula and star clusters, plus the occasional bright comet.For a beginnrer, a 4.5″ or 6″ Dobsonian reflector telescope is a great way to go. Don’t get an “equatorial” - it’s too complicated and heavy. In light polluted cities your best objects will be in the Solar System - Moon, Saturn, Jupiter, Mars, Comets. Jim
