Can it be used with an eyepiece to image at a greater power or can it only be used at the prime focus?

I do not know.... I suggest you contact Celestron tech services for this question. After thinking about it, I think you can do it....Sorry for the weak answer...

No. This goes in place of your eyepiece. This device is the equivalent of a 7mm eyepiece, which will already result in high magnification images. If you want to go further in, as many people do, then something like a 2.5X barlow lens should be employed. That's the next thing I'm going to acquire. I'm thinking that Jupiter with a 2.5X barlow will nearly fill the 640x480 frame size on my Celestron 8", with enough room to keep the image tracked. The frame stacking software, Registax is where the magic occurs. The videos you take of planets from this thing will not wow you, but after stacking they should.

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.

This is meant to be used at prime focus. It can be used with a Barlow, Televue PowerMate or Explore Scientific focal extender, but this is still essentially the same as prime focus.

It is equivalent to a 5mm eyepiece so it already is about all you can use. The answer is yes you can use a 2x multiplier, I did but even with the electric focuser on the telescope it was very hard to get focused and you can not see any useable gain.

Yes, this adaptor can be used with different eyepieces for different magnification shots. It is just another piece that gets added after the eyepieces.

You could but the field of view at maximum zoom would be extremely small. Also the quality of the optics are probably not going to deliver the clarity you desire

I am taking astrophotographs with this telescope using a Canon EOS REBEl 2Ti coupled to the eyepiece focus. I was able to adjust the balancing of the telescope of the telescope with the camera attached. I so far only taken pictures of the moon because I am in a light polluted area. I am waiting to take the telescope to a dark sky area so a can try photographing deep sky objects. I posted one of my best photographs of the moon on my facebook page if you like to see what the Powerseeker can do.

You can, but have to set the polarizer after focusing. Typically not a problem for distant / landscape shots as the ring is mostly around infinity focus.

Not very well. Unless you are viewing a non-moving object or have a tripod to look at a single object, the shakes and wobbles nullify any "zoom" power. Nice binos, but I would rather have gotten a telescope for any power viewing.

This would like telescopes that claim 500X power. It's just not possible. When you get to high power optics, all the pieces become super critical, especially the stand or mount. At high magnification, even a slight vibration destroys the view. The Practical limit is probably 1/2 of what they are claiming. But, that is still good for many study applications.

I have used it on the C8 and Meade 12, SCTs, and it works great with a 2x barlow on these scopes. I do not have a 3x. As far as the AstroMaster, I think the barlow would be too much power, JMO. I would try it with the zoom alone and see how it resolves at the lower fl range. I've had mixed results with the lower focal lengths on this ep. Of course, the higher seem better. I use this mainly as an indicator of the seeing conditions and the best fl for the object I'm observing. Then I usually change to that dedicated ep that fits the condition. It's hard to get a multipurpose ep to perform as well as a dedicated fixed fl one. However, again it does work pretty well on the higher fl. Hope that helps. WEK.

This Focal Reducer will screw in where the back is. You unscrew the back, screw this on, then screw the back back on. Also, this is really designed for Astrophotography. It will work for visual use, but most people get this for AP.

I was able to fit in my smaller eyepieces in the adapter. There is a knurled screw that will hold the eyepiece in place. I've also found that it isn't designed to be used as a primary focus adapter unless you have a low profile focuser. Has anyone been able to find any larger eyepieces that will fit in the adapter?

First extend it to full length, then adjust the focus. And you can only use it for distant objects. I don't have it now but I remember it do require some trial and error.

the focus range on this insturment is verry small,I dont believe it will focus,some of my fixed eyepieces will not focus.Hence not enough travel of the prosm.

1.25; if you have better magnification eyepieces the scope does work well with them. The two that are sent with the scope are fine but with a little higher magnification, it still works well. The 20mm and 10mm are great for lunar observation especially near the limb. I can make out Jupiter's moons with the 10mm and I had a 8mm and could easily make out Saturn's rings without too much distortion. I even think this little scope could pick out the Cassini division if Saturn was more inclined.

no,it is manual focus, and lets in a lot of light under certain circumstances. It is awesome for close up shots of the moon or stars.

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.

Yes, it is specifically designed for Powerseeker telescopes. It provides additional eyepieces that complement the ones that come with the power seeker, so you have additional magnifications available. Also it includes filters to make viewing details of planets easier. With a 50mm telescope you probably don't need the moon filter--it is used with larger 'scopes when the moon is so bright it is uncomfortable to look at.

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...)
