Even though it has an external threaded housing, it can accommodate an eyepiece. This is a lovely Barlow. You are unable to visualize- It can be used with or without an eyepiece in conjunction with a DSLR or astro-photography system. camera for image capture
When an optic is placed in the visual light path, the image quality is slightly degraded, but this Barlow does a good job of minimizing that degradation and allows you to see whatever detail is available at twice the magnification, which can be very pleasing to the eye. If you're looking at Jupiter through your telescope and it's fuzzy, this Barlow will simply double the size of that fuzzy image without necessarily making it "fuzzier." It's not going to make things "clearer."
If you use 2" to 1" telescopes, it should work. Adapter for a 25" screen I can't tell you how to get proper back-to-back-to-back back-to-back back-to-back You'll almost certainly need an extension tube or a 90-degree mirror in the focal plane to achieve focus.
Take an eyepiece, place it in your scope, and look through it. Then put the same eyepiece into the barlow and into the scope; if the image isn't double what you saw before, it's defective and should be returned. Every time I watch, I use my 2x and 3x Barlows.

) is highly recommended. inch scope). I live in a light-polluted city and chose the small and convenient 4 as my mode of transportation. To show my young children Jupiter and Saturn, I took my 12-inch StarBlast Dobsonian telescope to a park field. The first night, when I only used the StarBlast's two eyepieces (17mm and 6mm), I was extremely disappointed. I used to use 8-inch binoculars as an amateur astronomer. Saturn's ring and Jupiter's stripes were clearly visible through a 12-inch Dobsonian telescope. However, even with the StarBlast's 6mm, Saturn's ring was so small that my 4-year-old couldn't tell it was Saturn, and Jupiter's stripes were so faint that I couldn't tell it was Jupiter. (Though the Jovian moons could be seen clearly. ) ) I reasoned that I should get a larger scope. But I decided to get some StarBlast accessories and give it another shot. br>br>I went out and bought this Barlow Lens 2X (Bysameyee 1. 25-inch television ($26) and an Orion E-series television ($26). Series 7- $63 for a 21mm zoom eyepiece. Using either of them immediately revealed the StarBlast's true potential: my 4-year-old could clearly see Saturn's ring, and we could just make out Jupiter's stripes. Given the close proximity of a quarter moon between the two planets and the fact that we were in a light-polluted city, I was very pleased with the results. The children were ecstatic because they were able to recognize the planets with ease. Of course, using both at the same time was ideal. br>br>If you only have time to buy one accessory for the StarBlast (either the Barlow or the Orion Zoom eyepiece mentioned above), go with the 2x Barlow Lens. Because the Zoom eyepiece can only zoom to 7mm, not 6mm, using the Barlow with StarBlast's 6mm eyepiece gave the best view. However, because the 6mm has such a small field of view, it was sometimes difficult to find the object as these stellar objects move all the time and kids occasionally bump into the scope (the red dot finder isn't as user friendly as a Telrad, but that's not a big deal), so I had to rely on the 17mm to zero in on the object and then switch back to the 6mm. However, switching back and forth was inconvenient for me because I have small children. So that's where the Orion 7-star system comes into play. This is where the 21mm Zoom comes in handy. Wow! I don't have to refocus during the zoom because it's so easy to find things when they move out of view. When the entire quarter moon fits in the 21mm and the kids can ZOOM into the 7mm themselves to examine some craters in greater detail, it's even more fun. They had a great time! If you use the Zoom Eyepiece on the Starblast without the Barlow, you won't be able to see objects as large, but that's fine; Saturn's ring and Jupiter's stripes can still be seen clearly. br>br>In conclusion, I strongly advise purchasing both the 2x Barlow and the Orion Zoom to fully appreciate everything the small but powerful StarBlast scope has to offer! After all, in a light-polluted city, I don't need a large scope to inspire the kids! With the 2x Barlow and Orion Zoom, StarBlast provides all of the convenience, kid-friendliness, and astronomy potential that we require. P. br>br>P. br>br>P. br>br>P. I'll update my review once I've tried to observe some brighter galaxies (Andromeda) and Messier objects.
Other barlows with similar names are also available. For a typical telescope, this 2x barlow is sufficient. I like that the lens at the bottom can be unscrewed and screwed straight into any eyepiece for 1. There is a 5x magnification on this picture. I'm currently using a binoviewer to accomplish this, and it's working well. On Amazon, you can find a variety of different versions of this item. Except for the brand name printed on the barlow's body, they're all the same.
The Coronado PST produces a faint image, which I needed to magnify. Because the telescope has a short focal length, Barlows aren't always effective, but this one did. Because my ZWO astrophotography camera has a large CCD, this allowed me to utilize the entire surface area of the CCD. The Barlow appears to be in good condition. It's well-made and should last a long time if you treat it like any other eyepiece or lens.
However, it is much larger! I wanted to make Jupiter and Saturn appear larger, and I was able to do so! I was able to see incredible definition that I had previously been unable to see. I'm looking forward to putting it to the test on objects from deep space. This item is of excellent quality and is well worth the money!.
I bought this lens to get a closer look at the objects. With the help of the moon, I was able to confirm my suspicions. The image with the smallest Moon is without a lens, while the other two have one. The view nitidez is excellent. I was enthralled by it.
Beginners will love it. For the money, this Barlow lens performs admirably. It was a good fit for my 70mm beginner telescope. This is a fantastic option.
I wanted to get a little more magnification out of the lens set that came with the telescope without spending too much money. This particular Barlow 2x lens was ideal for the job. This purchase has made me very happy.
It works great and gives the telescope enough travel to focus by moving the focal plane closer to the camera sensor.
