Perfect size fitting, clear and better than the default eye piece that came with my telescope

This 2x barlow works fine for your average telescope. I like that you can unscrew the lens at the bottom and screw directly into any eyepiece for 1.5x magnification. I’m currently doing this with a binoviewer with good results. There are many other variations of this product on Amazon. They are all the same other than the brand name printed on the body of the barlow.

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.

I needed to magnify the faint image which is produced by the Coronado PST. The telescope has a short focal length so sometimes Barlow's don't work well but this worked fantastic. My ZWO astrophotography camera has a large CCD so this really helped take advantage of all the CCD surface area. The Barlow looks well-made and should last for many years Provided that you take care of it just like any other eyepiece or lens.

This was given as a gift. The recipient was very pleased. He had never heard of a Barlow eyepiece before. I would reccomend this eyepiece.

The lens has a bunch of weird stuff on it that I couldn’t clean off so it makes the image very blurry. But that’s the price you pay when you go cheap people.
