Yes, you have yourself a refracting telescope with a 60mm (2.4 inch) main lens diameter offering anywhere from 56x power of magnification to 525x depending on your combination of eyepiece mm (the smaller the eyepiece lens diameter the higher the magnification). You have a 1.5x power erecting eyepiece which will invert the image so it can be viewed normally, where up is up, down is down as when viewing terrestrial objects as apposed to space objects where there is no up or down.(a matter of relational reference). The Barlow lens allows you to attach an eyepiece of a particular power and will increase the focal length of the lens up to 3x (3x in your case, Barlow comes in different powers). Sometimes the Barlow lens allows you to slide the inner lens along its holding tube to any power in between the maximum power giving you 1.5x, 2x, 2.5x and 3x the magnification of the eyepiece. The Barlow adds another element (optical lens) between the main lens and the eyepiece thereby decreasing the amount of light to the eyepiece so things would look a lot darker than when viewing through no barlows. The larger the main light gathering capacity element (main lens in a refractor, main mirror in a reflector) the more powerful the instrument. As a rule, reflectors are less expensive because the mirror is easier to make then perfecting a lens giving the consumer more bang for their money. I own a Meade 8 inch Newtonian reflector on a motorized equatorial mount, which with a camera adaptor allows me to attach my old SR101 Minolta camera effectively making the telescope a huge telephoto lens. Its what got me started in photography forcing me to set a room aside as a darkroom for instant gratification since I didnt have to wait for the B&W pictures from the drug store to develop them. Living in New York City, with tons of light pollution, made my telescoping adventure short, and I no longer use the scope and have it all discombobulated in what was once my darkroom. Cleaning the main mirror one day, I lost my grip and the mirror slid down the main tube cracking it on the adjusting knobs at the bottom end of the scope. You can still view through it but now the gathered light is scattered haphazardly along the scope. (sigh) Heres a company pic of my scope, mind you, it measures 5 feet in length, is 8 inches in diameter and weighs about 100 lbs. with the counter weights. Scope
