    • Highly recommended for the StarBlast (a small 4.5-inch telescope)
Size: 2X
I live in a light polluted city and took the small and convenient 4.5-inch StarBlast Dobsonian telescope to an open park field to show my young children Jupiter and Saturn. I was very disappointed the first night where I just used the two eyepiece that came with the StarBlast (17mm and 6mm). As an amateur astronomer I previously used 8-inch Dobsonian and could easily see Saturn's ring and Jupiter's stripes. But even with the 6mm on the StarBlast, Saturn's ring was so tiny that my 4 year old couldn't tell it's Saturn and Jupiter was so so tiny I couldn't see the stripes. (Though the Jovian moons were clearly visible.) I thought perhaps I should get a bigger scope. But I decided to get some accessories for the StarBlast to try again. I immediately purchased this Barlow Lens 2X (Bysameyee 1.25 Inch, $26) and an Orion E-Series 7-21mm Zoom Eyepiece ($63). Using either one immediately brought out the true potential of the StarBlast: Saturn's ring was clearly visible for my 4 year old and we can faintly make out the stripes on Jupiter. Given there was a quarter moon close between the two planets and we were in a light polluted city, I was VERY satisfied with the results. The kids were excited because they could easily identify the planets. Of course, using both together was the best. If you have to buy just one accessory (either the Barlow or the Orion Zoom eyepiece mentioned above) for the StarBlast, go with the 2x Barlow Lens. Using the Barlow with StarBlast's 6mm eyepiece gave the largest view (since the Zoom eyepiece can zoom to 7mm, not 6mm). However the problem with the 6mm is that since it has such a small field of view, it was sometimes hard to find the object as these stellar objects constantly move and also kids sometimes bump into the scope (also the red dot finder isn't as user friendly as a Telrad, but that's not too much of a problem) so I had to rely on the 17mm to zero in on the object and switch back to the 6mm. But since I have small kids, it was a hassle to switch back and forth. So that's where the Orion 7-21mm Zoom comes in. Wow! So convenient to find things when they move out of view, I don't even need to refocus during the zoom. It was also extra fun when the entire quarter moon fits in the 21mm and the kids can ZOOM into the 7mm themselves to look at some craters in detail. They had a blast! If you just use the Zoom Eyepiece without the Barlow on the Starblast, you don't get to see objects extra big, but it's fine, you can still clearly make out Saturn's ring and barely Jupiter's stripes. In conclusion, I highly recommend getting both the 2x Barlow and Orion Zoom to bring out all that the small but mighty StarBlast scope has to offer! I don't need a big scope in a light polluted city to inspire the kids after all! StarBlast with the 2x Barlow and Orion Zoom give me all the convenience, kid friendliness, and astronomy potential we need. P.S. After I try to observe some brighter galaxies (Andromeda) and other Messier objects I will update my review. ... show more

I use this product to look at planets, it magnified well and it's good, but there's a faint dark spot on the barlow which i just received so i did not break it and i tried cleaning incase it was dust but no it's still there.
