can a 2xbarlow lense be added to this scope to magnify the viewing power?

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.

Yes, but you may be disappointed by the result. The barlow lens will boost the magnification with the 10mm eyepiece to 80x. Even if everything in your scope is in good alignment you'll probably find that the picture at 80x is noticeably fuzzy. Unfortunately, not every one of these telescopes seems to be aligned well at the factory, so you may find the 80x image in yours is much worse than that. The Travel Scope 70 is really made for low-power views, and Celestron is to be commended for not making exaggerated claims about high powers. The 20mm (20x) and 10mm (40X) eyepieces that come with the telescope are good choices. Yes, but you may be disappointed by the result.

No way. This scope is a disappointment. Clear up to 3x and that is it. Anything past that its blurry.

not possible. the lenses screw on one at a time. the uv filter doesnt make a difference.......take a look at this yourtube vid.....http://youtu.be/3g2NvQ6DfV4

Yes it sure could. I have one eye that had a retina bleed and went almost blind and I can see to string beads on the elastic. It has two sides so I'm sure if one side isn't enough turn the magnifier over and that side will be stronger.

Good question. Maybe--if you want to play around with it and possibly buy parts to make it work. If you need two mounting points, one for the scope the other for a camera, this unit won't provide that as is, and if your scope has an angled eyepiece like mine it is probably impossible. You could end up spending more on adapting this for your use than just buying a digiscoping bracket.

I have not measured out any area to view with the scope, so I can not be certain. As the mount for this device is not particularly great I usually end up putting the plastic ring around what I intend to view & zoom in to focus. Is it possible to take 1 cm2 shots with it, likely yes though you will have to experiment with focal lengths to get the magnification & field of view that you want. This device is more of a toy than a piece of lab equipment mainly due to the iffy base & the magnification dial's placement. If something more lab grade that is what you are looking for I recommend a more typical microscope such as this one: http://www.amazon.com/iOptron-ST-80-Digital-Microscope/dp/B0032VFC84/ref=fs_patw_1 It has higher magnification, a backlight, & multiple objective lenses. I hope this was helpful.

It depends on both the scope and the eyepiece. While the Barlow will increase the magnification by that amount you don't want to exceed the resolving power of the scope since you'll lose image quality and not gain additional detail. There are web calculators available that can help you figure out magnification and resolving power.

no, to do what you want you would need a telescope with a computer drive and software, as others have said you can see an object thrugh the view finder but no magnification. Also, my unit is very sensitive to magnetic interference which has required me to leave my deck and go out into the yard away from the house and garage.

A magnifier isn't designed to work with this kind of optic from what I understand. Plus mine didn't work anyways, so it would be pointless.
1996838
yes, but the only way you can see the object if to place it practically attached to the lenses. this Item its not worth it for what its intended to use.

Hi Thomas, This scope does not have that feature. There are some that can do that but cost more. This is an excellent scope the images are sharp, the LED light is very bright and the intensity can be adjusted. The work distance between the bench surface and the Light can be adjusted with the auxiliary lens attachment. The only problem I found is the instruction manual it came with is useless, I had to figure how to assemble it by looking at pictures on the internet. Also the two eye piece lenses do not come with the two set screws to hold them in place. they can fall out and break if turned upside down. Other than that it is a good scope.

Magnification is the focal length of the scope (in this case 650mm) divided by the focal length of the eyepiece. The shortest included eyepiece is 10mm. So with what's included the maximum is 65x. If you get shorter eyepieces or a barlow you can easily more than double that. But you'll rarely use such high magnification. Atmospheric distortions become very visible at high magnifications. It has to be a pretty clear evening for me to even WANT that much power. (On most nights the limiting factor is the viewing conditions, not the telescope...)

If by unlimited, you mean can you treat it like an EOTech, the answer (at least for me) is no. Though it is a true 1 power scope when set that way and I do shoot it with both eyes open when I have it set to 1 power.

not sure if that is the way to go. This is a first gen scope. I've added a high lumen IR light. http://www.amazon.com/Armasight-IR810-Detachable-Infrared-Illuminator/dp/B007SYMPMC/ref=pd_sim_sg_4?ie=UTF8&refRID=0DQN8W6P0QGS4BDVPGHQ and it increases the ability. A laser would be redundant with the lit crosshairs. Just a thought. Also, if you can afford a 2nd or 3rd gen, the difference is incredible.

Yes! I works well but the magnification is different from the standard eyepiece.
1627516
Yes you can, but bear in mind with the lenses on that the focal range gets nearer and narrower - e.g. with the 10x lens you won't be able to focus beyond about 2 inches and the depth of field is about 1/4 of an inch.

No. Additionally, the magnifying lens is placed too low to be useable. Don't buy it.
