i own a Orion 10013 GoScope 80mm TableTop Refractor Telescope will i get a clean, clear large image with this barlow? or should i buy a 2x or 3x?

Michael, I purchased the Orion 8715 5x high power Barlow lens for $169 and got a fine crisp image from it .I also liked the heft of it and the cool inner brass ring. Only thing is, a $39 3x. Barlow is not only just as good, but allows me to utilize a wider range of my eyepieces. Lemme put it to you this way...the overkill factor on the 5x Barlow is insane, to say the least.

Chis... Your question is incomplete. The Universal T-Adapter has two applications. Visual observation and Astrophotography. For astrophotography, the T-Adapter attaches your camera to the visual back of the telescope and proides a focal-plane imaging system. No occular (eyepiece) is used. However the built-in Barlow lens provides an effective doubling of your telescopes focal length (i.e. a 1000mm f/10 SCT is effectively a 2000mm f/20 "lens"). For visual observing, the adapter will accept any 1.25" occular. The Barlow lens is removable for either application. For eyepice-pojection astrophotography, consider the Tele-Extender Deluxe. This will allow you tu use most 1.25" occulars as a projection lens. Not that the optical speeds of this approach is extremely slow. f/30 would be good. So it is only practical for very bright objects (planets, moon, etc.).

Are you focusing right? I have the same telescope and I can see the bands on it with just the stock lenses. This is in Southern California too with light pollution. I have this barlow lens as well, and it does help with the bands and rings.

Yes, but you need to be aware that there are limitations to ground-based telescopes, particularly small scopes like this one. With a 76mm aperture (diameter of the tube), the maximum usable magnification is something like 150x, give or take. The 300mm focal length determines the level of magnification you can get from each eyepiece (divide 300 by the eye piece focus, so 15mm eyepiece is 20x magnification). This scope comes with 10mm and 20mm pieces. A Barlow (check out "Celestron AstroMaster Accessory Kit Telescope" for a tidy kit) can double or triple the magnification. Planets are big, but they are still far away. Even at 50x (6mm eye piece or equivalent), Mars will still look like a large red star. Venus, in addition to being hard to view because of its position relative to the sun, is covered by a dense cloud layer; you can see that it is a disc rather than a distant star even at lower magnifications, but there isn't a lot of detail to see through a small (or large) scope. Jupiter is much larger and better for viewing as a result. At 50x, it will still be small, but it should be easily recognizable as the gas giant we know and love. You should even be able to see the four bright dots in a line that are the planet's four largest moons. At 100x, the banding in its clouds should be clear. Saturn is smaller and farther than Jupiter. Still, you can see that the shape is distorted. A little more power and the cause should be clear: the rings. With my larger scope at home, by 125x (doable on this scope with the right equipment) it is clear that the rings are spaced away from the planet. Uranus and beyond, though, are beyond the reach of this scope, at least if you wanted to see more than a dot. So, yes, you can see the closer planets, but you need to keep your expectations realistic. I'd strongly recommend a Barlow and a decent eye piece. There are a number of kits, some less than $50, that should do nicely in that regard. Even without, there is still quite a bit to view in the night sky.

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!!

Some good eyepieces, not with too small focal length (no less than 10mm) and a Barlow lens. The ultima duo eyepieces are quite good.

Definitely probably. Depending on your application, you may never need less than about 15mm focal length. I'm not familiar with the hyperion zoom. Normally zoom eyepieces are more expensive and give a lower quality image than similar fixed focal length eyepiece. But they are popular for their convenience. I bought an orion sirius plossl 17mm eyepiece that is about as much magnification as can be used on a normal sunny day due to mirage and thermal effects. If you plan to seek and find those occasional days with perfect seeing, either at dusk or dawn or at night doing astronomy or similar, then you can possibly find a use for more magnification. In mornings with my 17mm eyepiece I can resolve a 1/4" hole in a piece of paper at 600 yds. This is only 73x or 15x/in. Theoretically, with good seeing you might use up to 50x/in or 250x. So to achieve 250x you'd need a 5mm eyepiece or a 10mm eyepiece with a 2x barlow. High power and barlows work best with bright objects--the moon or planets, bright double stars, etc. I think the 8mm of the zoom will likely be all you'll ever need. OTOH, you might find using the zoom, or a longer focal length eyepiece, with the barlow to achieve higher magnification to be more comfortable. So yes, they will both work. they are both designed to work with a scope like this. But they might be overkill. --Jerry

I was in your same situation last year. There is no such thing. The camera you purchased is designed for low-level light objects, not bright planets. If you use this camera for Jupiter per say, you will lose much of the resolution due to a half second exposure. Brighter objects are easily over exposed and you can't use any barlow lenses. However, I did purchase another Orion StarShoot but for planetary captures. You could of course use a standard camera for both jobs but if you are like me, I like the technology that Orion makes so I can use my laptop.

Yes. I have the 4.5 StarBlast and it is a great beginning scope. Add some filters and 2.5x Barlow and it's even better.

A 3 or 5x might be a bit much for that scope. A smaller 1.5 or 2x would be a better fit. All a Barlow does is increase your magnification. A 2x would double the magnification of whatever eye piece you use. Rule of thumb for maximum useable mag is 50 times the aperture. The aperture of the 127 is 5 inches. So the highest useable mag would be around 250x and that would be with perfect viewing conditions.

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.

A barlow is fine. I use the GSO Barlow that actually gives you two magnification choices... http://agenaastro.com/gso-1-25-2x-achromatic-barlow-lens.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.

The 10mm eyepiece that comes with this telescope should work very well to see planets clearly. While increasing the magnification will increase the image size, it will never be very large in the eyepiece.

LOL Oh no, ask away!! Personally I believe a reflector scope will be much easier to use than a refractor. Yes, you should still be able to see Saturn and it's rings. Even with a scope having a greater aperture and a high magnification lens you will not be able to discern much in the way of surface features. In a good dark sky area and with ideal conditions you might be able to pick out some cloud bands and that's about it. BTW, even with a XT4.5 you will also be able to see the largest 4 of Saturn's moon's orbiting about it! If it is within your budget I would bump the scope up to an XT6, if not then the XT4.5 is still a fine scope for starters. Also, have you considered a good pair of binoculars? You will still be able to see Saturn's rings and binocs can afford you some truly impressive views of the milky way as well as star clusters and some comets. Their wide field of view can make for some stunning viewing. I'd recommend getting a tripod with binoculars so you can keep them steady while viewing. Binoculars are a fine way (and can be even cheaper) for beginning to learn the night sky.

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.

Hello, First issue is the use of a reducer/corrector with a barlow multiplier. The two lenses are working against each other to no effect. Use the eyepiece alone or use it with the reducer corrector for lower power (wider fields of view) or use the eyepiece with the barlow for much higher power (smaller fields of view). If you have the Celestron Edge telescope I do not believe the reducer/corrector will work correctly. Hope this helps.
