At the discounted price, there wasn’t much to lose and I have to say I’m very impressed. It’s reasonably light but still well made, the zoom is very smooth and the eye relief ok. Although the field of view gets smaller at lower magnification, it’s acceptable and the clarity of view and contrast seems good. It was cheaper than most nasty single focal length eyepieces but much better. I’ll definitely use it with my travel scope and possibly with my other scopes. Review: Give your budget scope a new lease of life. Buy one of these - Speaking as a recent returnee to stargazing and using a recently purchased second hand Sky-Watcher Heritage 100p scope I was seriously impressed with this zoom eyepiece. My first night out with my little Dobsonian scope was quite disappointing. With the views of the moon showing serious colour fringing with both the 25mm and 10mm eyepieces I was unable to get good focus. Trying to see the rings on Saturn with the 10mm and 2x Barlow that came with it (80x magnification) was virtually impossible. However, I remembered having to upgrade the eyepieces on a previous telescope that I owned years ago to get the best out of it, so I did some research and saw some good reviews on the SvBony Sv135 zoom eyepiece. Having never owned a zoom eyepiece before I was somewhat reticent about pushing the Buy button, but boy am I glad I did. Views of the moon are fantastic through the full range of magnification with this eyepiece without a Barlow (16x - 57x on my scope). I could also get good focus on Saturn's rings at just 57x. All of this with very little (almost none) colour fringing. I'm now looking forward to pushing my little scope's boundaries further with a good Barlow. Summing up: If you have one of theses small scopes and have been a less than impressed by it's performance, try this eyepiece from SvBony. ## Features - Zoom eyepiece; Focal length 7mm to 21mm stepless adjustment; Precise and sensitive adjustment of the magnification;fit for observing planetary, nebulae, clusters - Crisp image;6-elements in 4 groups and real FMC film increase the transmission of lights;internally blackened eyepiece barrel to avoid internal reflection - Comfortable;16.3mm-18mm eye relief fit for those people who wear glasses or not ;40°-57° wide field of view;40° field of view even in 7mm focal range - Zoom eyepiece 1.25in;standard 1.25in size fit for any 1.25in telescope and accessories;M28.5x0.6 thread can coonect with any 1.25in filter - Portable durable;Package with two covers and package box to protect your eyepiece and convenient to carry and storage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Z64NK65 | | Best Sellers Rank | 16 in Telescope Accessories | | Brand | SVBONY | | Brand Name | SVBONY | | Coating | Fully Multi-Coated | | Compatible Devices | telescope | | Customer Reviews | 4.5 out of 5 stars 991 Reviews | | Exit Pupil Diameter | 3 Millimeters | | Eye Piece Lens Description | 6 elements in 4 groups, FMC green film | | Eye piece lens description | 6 elements in 4 groups, FMC green film | | Field Of View | 57 Degrees | | Finderscope | Reflex | | Focal Length Description | 7-21mm | | Focus Type | Manual Focus | | Item Dimensions D x W x H | 10.8D x 7.7W x 6.9H centimetres | | Item Weight | 230 Grams | | Manufacturer | Svbony | | Manufacturer Part Number | EUW9105A | | Model Name | SV135 | | Model Number | FAUW9105A | | Model name | SV135 | | Mount | Fixed Mount | | Number of Items | 1 | | Number of Packs | 1 | | Objective Lens Diameter | 21 Millimetres | | Objective lens diameter | 21 Millimetres | | Optical tube length | 93 Millimetres | | Optical-Tube Length | 93 Millimetres | | Power Source | Zoom Eyepiece | | Product Features | 40 degree - 57 degree wide angle field of view, 6 Element 4 Group, Fully multi-coated, Zoom 7 to 21mm | | Product Warranty | We provide 1 year warranty for Svbony telescope accessories and 30 days no reason to return.

Best regards, Karen **Q: Is this eyepiece good for Saturn and other planets?** A: I have a very basic telescope and with this lens I can get a very clear view of Saturns rings. Jupiter is a little harder but I can see the stripes at the moment as it’s close. The beauty of this lens is being able to change the magnification without loosing the target. So no more changing lenses. **Q: Can the rubber eyepiece cover be removed to reveal a thread to mount a T adaptor ?** A: Hello, the rubber eyepiece cover can be removed, but there is no thread inside.
