Apparently no prisms, but with that wide view not Galilean "field glasses"--and eyepieces offset from objectives. Anyone understand the optics?

Sorry. Don't understand the optics. I just know that these things are perfect for watching San Diego Charger games at Qualcomm Stadium. Very wide range.

only thing i understand is that they are very good. i have so enjoyed watching ballet with them.

The image is inverted. This is a really amazing telescope, eapecially for the money!

No, the prisms are pretty much fixed. The other concern I would have is the narrow perspective, and the change in way visualized objects move, can make you feel unsteady.

There is no view finder. The lens is a wide angle type and I've not had any issues with it not picking up a good field of view.

Here is Aleksandr K. again. Look at some pictures I made using Celestron 5 MP (their sizes were reduced).https://www.facebook.com/media/set/?set=a.586148731439698.1073741832.100001337299954&type;=1&l;=b176410e3f

If you wear glasses, they need to be on. There is no adjustment. It is just one field of view.

Paul, thank you. From the specs alone, I agree, but I think there must be some significant difference between the two sets. The only thing I can see from the specs is something about the eyepiece adjustment.

All the images in these make of telescopes are inverted but there are erecting adapters available. I have never used one because they are for refractors and Schmidt Cassegrain. The angle might be a hindrance.

I also see an oblong dot, almost a set of dots that seem not round. I was diagnosed a few years back with a "mild astigmatism", and although I do have glasses, I generally do not wear them. I was unsure if it was the astigmatism or a faulty unit, so spoke with Trijicon on the phone and they said to exchange the unit with a new one. I did so through Amazon and found that the new unit did the exact same thing. I believe that its the astigmatism, and although mine is so mild that I don't have the need to wear glasses, it still makes the laser dot seem oblong.

I am a new be, but when I received my scope the problem I had was getting the finder scope to match the telescope. My view was also blank. Using the wrong eye peice can cause the same problem. The wrong focal length, due to eye peice, and or the wrong eye peice tube. I had to fiddle with it for a while, I started with small tube, and large eye peice, focused the scope with the spotter scope, best view of the moon with out being there. Patience, dont throw it out. I hope I could be of help, trial and error

The viewing angles are as shown in the photo as landscape. There is no portrait angle.

It is not actually a prism, it is a straight-through optical diopter sight. Kind of like a microscope. The original K&R/Eschenbach/Wilkie brand German march compasses on which these compasses are based utilized machined threads in the diopter housing and you could adjust the focus by rotating the black eyepiece. This compass may have either a nonadjustable eyepiece or one that is improperly constructed, thus may not be adaptable to your eyesight.

R all objects blurry when you look though the scopes eyepiece ? Or just the moon. ? Does it happen with all your eyepieces or just the one ?

Dobsons have the viewfinder up top. Depending on how it's angled, you may want a chair to sit in.

That tripod is worthless. I bought another larger one that telescopes from Midway for no too much money. Scope works well.

In theory, these should be excellent hand-held, low power, wide-field astro-binoculars. The low magnification paired with the relatively large objective, translates into a 7mm exit pupil. This is much better light transmission than the example 15x70 that was provided. However, I have no idea about the focus mechanism on these binos. If it is some sort of "auto-focus", then I would imagine it would be difficult for these to pick up something at infinity in dim light. Which, if this is the case, it is too bad because these would otherwise be wonderful for sweeping views of the Milky Way.

Assuming you mean the Milky Way, here's a good article : http://www.lonelyspeck.com/lenses-for-milky-way-photography/ and it shows you the field of view you can expect with the lens.
