I was able to see Saturn's ring clearly with 4mm eyepiece .Can I buy one 2x barlow lens and that will magnify 200X. Is this supports 200x?

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.

I could not get my Celestron XCel series 2X Barlow to focus. It was way beyond the focuser's travel and others have noted this but apparently Orion's Shorty 2X Barlow will work with this telescope as well as GSO 2x barlow from Agena AstroProducts. The useful magnification on this telescope is 200X but that is probably counting on optimum conditions. For planetary views with average conditions with a 100mm telescope, magnification of 100X to 120X are probably expected to be the clearest.

It could be you need an extention for eyepiece or your eye isn't cloce enough to eyepiece,or you are useing an eyepiece that has too short of a focal length. Try a 32mm or 36mm. If that works, work down in focal length. I tried a 6mm and saw a blure. Every telescope has a max magnification. The 8" with a 1200mm focal length maxes out at 450/460 power. With 5x barlow max 15mm yields 400x and 13mm yields 461x.

Using the stock eyepieces (20mm and 10mm) Saturn's rings, Jupiter's cloud bands and moons are clearly visible on a clear night. I have only had this for a few weeks but as my first scope it's great and would highly recommend it. There are also more eyepieces that can give you even greater visibility.

You can use barlow lense to double or triple the size of Mars. Unfortunately Mars is so small that it needs a much larger aperture, a steady go to mount and really god eyepiece to observe Mars in a much larger state.

It comes with a single 25mm eyepiece, so to answer your question outright, "no". But the 25mm is sufficient for seeing moons around jupiter and the rings of saturn with little effort. You can easily see nebula and some star clusters on a 25mm. I bought the http://www.amazon.com/Orion-08890-1-25-Inch-Telescope-Accessory/dp/B0069VXRLS/ref=sr_1_4?ie=UTF8&qid=1398047491&sr=8-4&keywords=1.25+orion+eyepiece set to fill out and have a nice starter set. Hope this helps

I don't see why not. I use mine all the time with my Orion 130ST. The Barlow lens should work on pretty much any reflector or refractor for that matter. It slips into the eyepiece socket on the scope and then your regular eyepiece fits into the Barlow. It does make the lens stand out from the scope another inch, but just rotate the scope on its mount to get a comfortable view. BTW, I've been so impressed with this lens that I also ordered a 5X Barlow to see if I can really bring Saturn in. Good viewing and Happy St. Patrick's Day!

It can be used with a 2x or 3x barlow to get higher magnification of the planets. May be harder to focus and harder to keep the image centered unless you have good tracking. Experiment! Ernest.

Hi Scott, Yes, you can see all three. However: Because the scope is a short focal length scope it gives a wide field of view and rather low magnification even with 10mm eyepiece (35X). If you can obtain a 2X Barlow, a power booster lens that you put between the eyepiece and the focusing tube, you will be able to have 70X magnification with the 80mm Go Scope. I bought a 7mm wide angle eyepiece for mine, which gives a magnification of 100X with my Orion Shorty Barlow. This gives very good views of the planets and spectacular views of the moon. Keep in mind, that "seeing conditions," that is how steady the atmosphere is any given night, can be the biggest factor in how good a planetary image will be. It can vary quite a bit, night to night, so if you don't get a sharp image of the planet, don't blame the telescope. Try another night. Also, particularly with Mars, it depends how close to the Mars the Earth is at any given time in our orbits. I have had only so-so views of Mars with big telescopes with high powers and steady seeing conditions when the planets were at great distances from one another. On the other hand, the clearest, brightest, and most detailed view of the surface features of Mars was through my 70mm Tele-Vue Pronto when Mars was at its nearest point in years back in 2004. And that view was obtained in the heart of a light polluted city! Hope this helps. If I can be of any further assistance, let me know. Sincerely, Joe R.

It is always better to keep the filter to the closest point from your eye. In this case, immediately below the eyepiece. Combining multiple filters may be useful to watch bright phases of moon and venus. For order sake, i would say Barlow, Filter, Eyepiece and Your Eye in order. The filters have thread which can help u screw and pile up. So Enjoy!!

The supplied eyepiece will show the rings. What level of detail are you seeking? Cassini's division? Given good seeing conditions, achievable with suppied eyepiece which is roughly 50X.I have used 150X for better results. Cheers!

If you don't exceed the magnification appropriate to the sky conditions, yes.Barlow and any good eyepiece from 32 down to 6 mm should be usable IF sky clear and steady. A Barlow plus 6 mm will result in magnification of 400 times in the XT8. That is the most power I could use and only on really bright objects. The Barlow is more useful to me with double- digit eyepieces, boosting the power of a 10,for instance, while keeping the bigger easier to see glass.A barlowed 10 gives 240x in a 1200mm long scope like the XT8.I sold my XT8 to buy a bigger scope but the XT8 is an excellent one.

When you apply the corrector you will have to dramatically change your focus setting. Because of this, I recommend not attaching the 2" Barlow lens initially. Then focus your telescope with only the 23 mm on a bright object. After that attach the Barlow and you may have to focus again.

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

Optica offers all adapters just ask them. They have outstanding customer service. This a great lens for shooting the moon but has no aprature ring so you need to set depth of field in your camera. This not a zoom but rather a fixed focus lens. I like mine but the moon after 750mm becomes to large to fit screen.

You can connect camera to this barlow. you need a 1.25" universal T adapter and the correct T ring for your SLR or DSLR. Google it both Meade and Celestron make one. http://www.celestron.com/astronomy/celestron-t-adapter-universal-1-25-in.html

Hello, I would say the images for me are the same as I have the basic eyepieces and two sets of as you need two sets for the bino viewers but what I like is the eye relief that you get when looking through them and a almost 3d effect like you get when looking through binoculars. If you can afford it I would highly recomend it, not for just yourself but for other viewers as well. I have a Celestron 8SE and looking at Saturn, Jupiter, the moon, well its pretty awesome. My plan is to do astrophotography, if I was really into eyepieces I would go with the two inch and some nice Nagler eyepieces. Hope this helps, Good luck and dark skies.

I've never seen two barlows used at the same time but don't let that deter you. This is an awesome barlow to use with large aperture scopes. I use it on my Orion Xt10 Classic Dobsonian with a 25mm lens. I use it with viewing Jupiter, Saturn, Mars, and all the other planets. With where I am (near a city) I lose some clarity with it but its magnification is unrivaled in my opinion.
