I bought a Orion SkyQuest XT10 Classic with a 2 1/2 Barlow with a 24/8 'm zoom lens. why is Jupiter so small and out of focus help

Try a 9mm,, 4mm is even better. I can see 4 of jupiter's moons pretty clearly when focused.

I wish you lived around atlanta and I could help you focus it. it comes with a focusing lens and some tools. Alan head wrenches. You can find videos on culmination. I can also say that if you are viewing city areas it will not be as clear regardless. As for the size of the planet. It comes with a 25mm lens you need a 4 or 6 mm lens to make jupiter look a little bigger but if then it is no bigger than a dime. Fell Free. The telescope is made to see distance objects. Like the orion nebula thousands of light years away looks pretty nice with higher mm lens like 25 or 40mm. Hope this helps. Seeing a galaxy or a planet like mars is really cool it just takes time to practice setting it up.

It's your back focus. For starters. You don't need a Barlow to view Jupiter. It is going to be small. You want a big Jupiter spend the cash and get a planetary lens or a nagler. Your looking for the image you see in pictures. You'll need a camera to zoom the image. Even with a 9mm planetary I get about 2 degrees of Jupiter ( aspirin size). Your focus point is minimal with a Barlow and an 8mm eyepiece. Not to mention loss of light and having your scope collimateddamn near perfect. Advice on focusing. Get an electronic focus control from Orion. It's adjustable to a very slow speed which helps. Sorry but the only way to fill Jupiter in your entire eyepiece is using imaging It's your back focus.

You need to culminate your scope . Im not sure what a 24/8 'm lens is . The scope comes with a 25mm eyepiece wich works really nicely with a 2x barlow . Try a 17mm or a 10mm . Dont expect it to be to big though remember how far away it is . But even with a 2x barlow and the 25mm eyepiece it comes with you will still be able to see the cloudbands and 4 of its moons .

If you're referring to the Orion 80mm tabletop refractor scope, that accepts 1.25 inch eyepieces then yes it should. Since the camera is akin to a 5mm eyepiece and the focal length of the Orion 80mm tabletop is 350mm, the camera will produce a 70 power image. Which is what the stock 10mm eyepiece combined with 2X barlow would produce. This camera should only work on brighter objects, such as the moon, Jupiter, Venus, Saturn perhaps. I'm not sure how tracking objects would work with such a scope, I use and equatorial mount. Anyways should work. I prefer the steady pics smartphone adapter for my astro-photography however, but that is me.

Pam that is exactly why I purchased the lens!! You will need a tripod . Took a little bit to get use to the lens, it's not auto focus. But I have some pics of the moon that are breathtaking ! Good luck!!

What type of T-adapter are you using between your T-Ring and the eyepiece socket of your telescope?I'm using a T-adapter that allows me to insert an eyepiece in the adapter. Without the eyepiece installed (prime focus mode) I can't adjust the telescope focus adjustment far enough out (back) to get it to focus at the moon, and it barely will focus on Jupiter. With the eyepiece installed everything works fine.

I cannot, but I can give you my perspective on the StarMax 90 mm by Orion. It is small, portable, and clear, but I wear glasses, and it is hard to see through with the 10x eyepiece. I think all of the small scopes will be. I wish I had spent the extra $100 and bought the 6" Dobsonian mounted reflector, but I wanted to use this during the day for spotting animals from a distance. I gave this as a present to my wife who hasn't worked with the telescope yet, and she may have different opinions. I did get her the camera mount, polar lens, and an extra eye piece that doubles the magnification. I think that you'll find that both are probably one in the same IMO. I do like the table top mount that the Orion has. I think once the weather warms we will be able to give a more thorough opinion. I think I will end up getting the reflector with the Dobsonian mount the color CCD eyepiece from Orion, and a few extras. If you have room I'd suggest the 6" reflector, or this http://www.telescope.com/Orion-XT45-Dobsonian-Telescope-amp-Beginner-Barlow-Kit/p/102027.uts . I feel that we may outgrow the Starmax 90, but I think the 4.5 or 6 with Dobsonian would well used for the lifetime of star gazing.

I have no problem making out Jupiter's stripes, but haven't seen the spot. I haven't had a clear enough night at a time of transit (http://www.skyandtelescope.com/observing/objects/planets/3304091.html?page=1&c;=y). In addition to what comes in the package, I added a 3x barlow lens to increase the effective focal length.

1- The focal distance is too small or too short , try adding some space between camera and the telescope focuser or removing it if you are using it . 2- The focus mode is in auto , try manual mode.3- The Telescope is not well collimated. Enjoy. Good Luck. Clear Skyes.

The Solar system Imager needs a 1.25 inch focusser. I'm using it with a Nextar 6SE telescope. The only other restriction would be if the focusser wouldn't let the device go deep enough to come to focus. I tried to use it with a homebuilt 10 inch Newtonian that I'm going to need to modify. That's not something you would want to do with the 130. Since yours is a Newtonian, it MAY have that problem.

The depth of field for focus on this lens is quite short. You need to put on the lens and then focus by hand.

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.

There is no magnification with this T-Adapter is good for prime focus....where your camera is receiving light directly from the telescope...the "magnification" will be from the scope itself and no eyepieces...if you want magnification...you need a T adapter that will allow for use with a barlow lens...which is mainly used for planets...as deep sky objects are far too big

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.

The 70 Travel Scope can handle a "Shorty Barlow" from the top of the diagonal. The Scope is 70 mm, so It's Magnification Max is 140 power. Your 20 delivers 22.5 Magnification, the 10 mm 45. The Scopes power is the ability to not surpass 2 X the MM appeture (front Lens Diameter) so 70 X 2 +140. A Two times barlow would double your current numbers; a triplet would get you 135 Power with your 10 mm. That's 5 mm under the scope capacity so as not to darken the Picture. This Scope is great BTW, we used It to film the Venus Transit across the Sun and other Dark Sky Objects, great for Landscape photography as well (on a budget :) Though make sure It's a "Shorty" Barlow Lens, some are too long to go into the "top" of the diagonal (you need the Diagonal because It's part of the 450 mm Focal lenght ) from the "tube side" you won't be able to focus. Celestrons shortys work well as Meades. Hope this helps.

Hello I'm not a expert but the telescope collimation might be off. The focus assembly could have a problem. Hope this helps.

Just last week I was able to pick out 3 of Jupiter's moons under city lights with these. Although I couldn't make out any banding, I could clearly tell that Jupiter was not just a point of light. I expect Saturn will look slightly oblong, but I doubt the rings will show up distinctly. Orion and the Pleiades looked impressive with the wider field of view than what my telescope gives me. Open clusters looked good as well. They're far more convenient than hauling out a telescope, but there are large trade offs vs a decent 6 or 8" dob telescope that will run 1/2 the price. But then a telescope is useless during the day for birding or sports. Just last week I was able to pick out 3 of Jupiter's moons under city lights with these.

Hey Iggy,Since I wrote, I did end up with the 8" Dobsonian Intelliscope. The answer is, the Orion scope is nicely balanced and with a little practice, you can get good at tracking objects by hand. With a 10mm eyepiece and 2X Barlow, which is a magnification of 240x on the 1200mm scope, you need to move the scope about every 20 seconds or so. You still need a motor driven mount if you plan on taking photographs, though.

There are several issues that could be here, depending upon your experience with telescopes and such. First question: could you see the moons in a more or less straight row on one side or the other of Jupiter? If not, it would seem you possibly aligned on a bright star like Castor or Pollux rather than Jupiter? The finder has to be aligned to the mail optical tube on a real object. I find the Moon easier as you can always find it by shadow, glare or just plain luck. Have someone hold the image in the scope while you tweak the finder knobs to get the red dot centered on some feature of the moon and have that feature centered in the eyepiece field of view. If you could see the moons, but no detail on the planet there could be a couple of issues. The more complex of which is that if your eyes are like mine, I need a bigger image to pick out detail. Yet observing buddies can see plenty of detail in small images. Go figure I guess. If you were using the eyepiece with the longer focal length number, the one with the scope might be a 20 or 25-mm I forget. Then once you have the planet centered or off to the leading edge of the field, switch to the higher power or the lower focal length eyepiece and refocus. Hope this is helpful!
