SVBONY Telescope Lens 4mm 10mm 23mm Telescopes Eyepieces

Why did you pick this product vs others?:Very good eyepiece. Great for the value.

I was shocked by how crisp the view I got from these eyepieces are when I first them in (one by one). I fully agree with previous comments that these eyepieces are decent and much much better than H20 (20mm) & SR4 (4mm) eyepieces I got together with the purchase of telescope.1) The build quality is not bad. Better than what I expect. The 23mm one is huge at hand and 10mm one is actually smaller than 4mm one. I would say 3/52) The optical quality is very good. The view is crystal clear and no apparent distortion. For 4mm one, the view is actually very crisp except for darker background. 4/53) The wide angle view is indeed with what it claimed. Viewing from 23mm even gives me a feeling like watching stars through a spaceship windows... 3/54) The eye relief is not very long but not bad. For 23mm, I can easily look through it when I wear eyeglass. Looking through 4mm is a little bit of harder to watch through with glasses but much better than my SR4, which is simply not possible. 2.5/55) The cost for those three pieces is low. $12 each. 5/5Overall, I would like to see that these eyepieces are well built, crispy clear and having wide angle view as advertised. In my opinion, if your budget is only about $50 and still want 3 decent eyepieces , this item is one ultimate budget choice.

With the current gold line and red line sets I'll call these the bronze line. Basic and cheap but more below. I am still learning collimation but I used a svbony laser collimator and supplied collimation cap and appears to be focused...They seem good, better than the 10mm and 25mm my virtuoso gti 150p came with.No eye cups. Didn't realize until I got them.Bought as 4mm 10mm and 23mm set, came in separate boxes In a plastic bag with dust caps on both ends.The 4 mm I didn't get the test during night but during day it seems ok for price. Dim and a little out of focus but might be me or the limit of my equipment or how i tested it. I did collimate but not going to knock it yet.The 10 mm was nice during night and day use, I have very little experience with other eyepieces other than the 'scope supplied 10mm and 23mm. Great views of full moonThe 23mm was odd, mine has a part of it that screws loose or tight at where you place into the 1.25" focuser. The silver part unscrews and I don't want to fully unscrew and damage or ruin it. Not sure if designed like that or a quality control issue. Works great other wise. Lol, turned it tight and it seems fine. Nice view of full moon.Two pics are one photo, but zoomed in on the second one. I just held an s20+ up to eyepiece. Don't remember which eyepiece I used, 10mm or 23mm might have used a 2x svbony Barlow. Second picture is an edited picture of the moon. More contrast and sharper to show details.Seems like a good starter set. Recommended brand. Getting the upgraded and seemingly well reviewed red line set soon..

I found a mediocre telescope at a second hand shop for 10$. It was a Celestron Power seeker 127. I know nothing about telescopes. Or know just enough to know I don't know.I didn't even realize the "big shiney fancy telescope" I found didn't have a lense🤦‍♀️, at least not till I bought it.Not wanting to spend a ton on a lense set to find something else was wrong, I did a little research and found something that suggested 4mm as an ok size for something like this.This lense was one of the cheapest and not horribly rated.I'm shocked at how clear my view was of the moon. For a foggy night, in the city. Wind blowing so hard it was wiggling the telescope. Overall a terrible night to try it but my 5 yr old is calling the shots and she could see the moon from a window inside so we had to test out the Christmas gift because according to her it was clear enough, I've added a photo of how "clear" it is tonight.This is what we saw with this little thing on such a horrible viewing night.

I've been enjoying astronomy for over thirty years, so I often have someone ask me to help them get started. It's always good to start simple and not spend a lot of money until you decide just how much you like it. Used equipment is a good way to start, and quite often, what gets bought doesn't come with an eyepiece. I bought one of these to go with some equipment I sold. But I decided to try it out first. I am very impressed. I looked at some faint, deep-space objects and was surprised to see how clear they were. So bottom line - a very excellent value. This brand has some great stuff for modest prices.
