![]() ![]() They work well, though you really need a short focal length eyepiece of 6mm or below to get reasonably good planetary views out of the StarBlast’s short 450 mm focal length, and a wide-angle eyepiece in the 25mm range will give you a wider and slightly sharper view than the stock 20mm does.Īs with most beginner scopes, the StarBlast 4.5 Astro is provided with a red dot finder for aiming-more than adequate given its ultra-wide field of view. The StarBlast 4.5 Astro includes two eyepieces: 20mm (23x) and 10mm (45x) oculars, seemingly of some variant of the Kellner or Plossl design. For mounting it on a full-sized equatorial or alt-azimuth mount, you’ll need a pair of tube rings and a dovetail plate. The StarBlast attaches to its mount with a simple clamping tube ring, allowing you to slide the tube back and forth and rotate it. The focuser is a standard 1.25” rack-and-pinion unit. It does need collimating, but that’s an easy task. And of course, it’s no contest when it comes to deep-sky objects. A light pollution map can be very useful for planning your observations.While primarily a wide-field instrument, the StarBlast performs pretty well on the Moon and planets, much better than the 60-90mm refractors often cited as good beginner scopes. Also, make sure you observe in a place with minimum light pollution. Use the Starry Night software for more help. You can expect to see the Andromeda Galaxy, the Orion Nebula, the Dumbbell Nebula, as well as some other Messier objects. In addition, this telescope is better suited to observe deep-sky objects than planets. The Moon, on the other hand, will look astonishing and sharp, just like you were in its orbit. With the 6mm eyepiece, you'll also begin to see Jupiter's gas bands. With the provided eyepieces Saturn can be seen as a tiny disc and you'll be able to make out the rings around it, but not distinguish between individual rings. However, better equipment is needed for observing the planets in greater detail. It means that it provides bright images of the Moon, planets, and even wide-field celestial bodies like nebulae and star clusters. The focal ratio of the StarBlast 4.5 is f/4. Using both, the 2x Barlow and the zoom eyepiece, you'll get maximum performance. You jump from one power to another, thus making it very child-friendly. ![]() It's convenient because you don't need to refocus it when the object moves out of view. The obvious solution would be to invest in better eyepieces, but instead of buying many of them, we recommend getting the Orion 7.2-21.6mm zoom eyepiece. Eyeglasses wearers will have a hard time here. ![]() However, the narrow aperture of the 6mm eyepiece could be uncomfortable to look through at such high magnifications. You'll be able to see Saturn's rings without much effort and Jupiter's gas bands will appear as faint stripes. Combining the Barlow lens with the 6mm eyepiece will give you the largest view.

Our suggestion would be to buy additional lenses and/or a 2x Barlow lens to maximize the potential of the StarBlast 4.5. Although, the Galilean moons will be visible as four bright dots around the planet. With the 6mm eyepiece, you can begin to see Saturn's rings, but you probably won't be able to make out Jupiter's gas bands. Jupiter and Saturn, the two gas giants, will look tiny. However, they are not ideal for planet observations. You can see Moon's craters and mountain ranges very well and with great detail. The included eyepieces are of decent quality. ![]()
