What is the aperture of this bino ? I see pictures of tree different models with the same Id.nr. Some say 18mm or 22mm. on Celestron site is 22mm.

There is no aperture listed. The one I purchased is model # 93691... I would go with what Celestron claims. It fits into the 1.25" eyepiece holder with no problems.

Saturn's rings are always a treat! Glad you saw them. A 2x barlow and 4mm eyepiece will give you 200x on this scope, which is about the theoretical maximum usable magnification for a 100mm aperture scope like this one (about 50x/25mm). But in my experience with these smaller scopes, the image is rather poor at maximum magnification; you can see something, but very dim and very grainy, for instance. For my eyes, the max usable magnification is closer to 40x/25mm..... I think it's fun to use the max magnification (esp. on the Moon!) But I usually get the most satisfactory viewing at a lower power. Enjoy your telescope! Saturn's rings are always a treat! Glad you saw them.

The threads should be the same for all Nextar scopes as far as my research has turned up. Good luck to you. Celestron is a good company and their products are all top quality.

Paul, thank you. From the specs alone, I agree, but I think there must be some significant difference between the two sets. The only thing I can see from the specs is something about the eyepiece adjustment.

As listed on the Amazon product description (read the details on any item you buy, especially online)...12 x 8 x 17 inches ; 3.3 pounds and the Celestron brand is well known as a maker of fine instraments in astronomical circles. Personally I found the binoculars a bit heavy for comfortable viewing without a tripod. These binoculars are apparently better suited for stationary work and stargazing. I do not recommend it as a general purpose binocular.

Did your Celestron 20x80 binoculars come with the integrated tripod adapter rod? If it did read the manual to make sure the thread size matches up with the thread size on this tripod. I would assume the adapter rod would be the universal size for all standard tripods but its always good to check.

Eyepiece (rear lens)is about 17.5mm, front lens is about 22.5mm. Excellent sight.

It looks to be the same as Cosmos, but I also have the Celestron. It all depends on what you plan on really using it for!

What type of scope were you using it on? My DSLR comes into perfect focus. You really do not want to use this to image Jupiter anyway - you should use a 4X barlow, to make it bigger, not a focal reducer to make it smaller.

Mine works well with the Orion 15x70, so yours should be fine in terms of size. However I am not familiar with where the screw fits on the Celestron. Advise you to compare the two binoculars. You can always return it if it doesn't work.

what size filter does your lens take? the sun shade that is pictured is a 52mm. if they are the same, then "the glove fits". Bob

I am new at this and unfamiliar with other models. I only know that it fits the Celestron. Maybe someone else will respond. Good luck.

A 6mm eyepiece will give you about 75x magnification. I get better views of Jupiter in my scope with 4mm and 3.8mm eyepieces at about 115x. I don't like using a Barlow.

I have not seen the Simmons. I am very pleased with my Celestron up thru 40X or maybe 45X. Above that, the optics are not as clear, and detail is not much more visible, even though the image is larger. Most of my useage is 1.5-2 miles looting at wildlife. At shorter ranges, the higher magnification would probably be adequate as well, that's just not what I use it for. Moon shots are impressive!

I have a Celestron C90mm Spotting scope Focal length 1250mm the importance here is the eyepiece...if yours is 1.25" AstroMaster acc.will work. do not expect super quality but is nice to have it !

You can see them fairly clear, i'll put a link at the bottom of my comment to a guy who takes photo's with his 4se. Keep in mind, when you're looking through the scope, the view is not as fuzzy as his photos and video. You can't magnify much more than 150x with the 4se but you can see Saturn with it's rings, and Jupiter very clearly. I'm not sure what the other person is talking about the motors jumping, mine tracks beautifully. This is a great starter scope, but, I also agree there are way better ones out there. For a first scope just to get you familiar with the sky and Astronomy, the 4se works great. If you're like me though, you'll probably want something bigger and faster within a year. I'm actually thinking about selling my 4se to step up to a much higher end scope for Astrophotography. May I ask where you're from? https://www.youtube.com/channel/UC7LIfGL0G50jj7sP_aktkHA
