Hi,

having used neither of the two I can only speak from experience with my Kowa TSN-3 (77mm fluorite) and 613 (60mm ED). They have similar weights as the two MM4 models although the TSN-3 might be...

Yes, 500AH on my Geo 530 legs (actually a predecessor called Carmagne 530). Works very well and I got both parts used for less than 150 euros together. Added a mulepack which makes it very comfy to...

Hi,

I just measured the inner diameter of the threaded eyepiece mount of my ancient Kowa TS-9 - it also had 27.65 mm or so - very fine pitch thread. I only have a 20x fixed EP for it, but 11-33x...

Hi,

the Geo 630 should be fine for a full size scope, as are my Geo 530.

not quite... the side by side test by chicago-al was a 501 vs an older MM3 50 ED with the HDF zoom (which he got a great used deal on) - a combination which was about double the price of the...

Hi,

that really depends on the eyepiece that comes with it, the price, sample variation and the intended use.

First of all, the 77mm Leica is a plain glass, full size scope - opposed the Vortex 65...

you will not get any larger true field of view though with a bigger binoscope... plus getting them collimated is a major pita.

TFOV in deg = 180/PI * EP field stop / objective focal length

Hi Pete,

apart from too much defocus the images look very usable. What distance is your artificial star at? 30m or so would be great.

Hi,

much less defocus is needed, you want 5 rings or so.

As for the line - roof prism edge was my first thought too, but it would be shocking if it was that visible... Also quite a coincidence to...

Hi,

congratulations to a very good deal! If you were already set on the 10x30 format and could try them so they work for you - perfect!

Hi,

congratulations to the 664 - a straight scope with an LER eyepiece is probably best for shooting.

Hi,

Or 3D printing as has been recommended by Binastro!
