To their credit though, Konus replaced it free of charge. Also, one of the locking screws on the base of the mount was so bent it couldn't be turned. I can't be certain if I did it or it came that way. I managed to open the base and straighten the screw myself. If I was unable to fix it, Konus was willing to replace the mount base for me.

i just purchased this scope used on the AM. And I can tell you it has excellent optics. 1/6th wave. Very smooth. The images MATCH my 8" Zambuto starsplitter tube on Saturn. The images are also much whiter than the SS. Slightly dimmer stars are noticed. Just as sharp as the SS. I also notice that this scope has a very smooth focuser, and the finder is second in sharpness only to my previous Tak 7x50!!! This is the 3rd Synta 8" scope I've checked out, and all 3 had premium figured mirrors. Two f 6 8" dobs had virtually perfect star tests with excellent spherical correction.

>There was one major flaw when it first arrived that does need mentioning here for would be “newbies”. Upon first light the images were severely degraded and a quick star test showed the problem immediately. The primary mirror clips were tightened to the point of causing the mirror to deform. The resulting image showed a somewhat “triangular” star pattern near focus (three clips are used on the mirror). I removed the primary cell and loosened the clips and recollminated the optics. The next night under the stars was a completely different experience. Star images were textbook!!!! This little scope was a surprise!!!!

I've just bought the same scope and I think I have the same problem! I haven't yet started to recollimate it - any tips?

Subject: Konus 200 OTA

I recently bought the Konus 200mm F5 Newtonian OTA to put on my Meade LXD500 mount, enhanced for Go-To operation. The OTA is Konus's older type with the thin spider vanes and 2 inch focuser. The collimation was severely off, which was fairly easily fixed using a cheshire peephole/crosshair device. However, star tests indicated a fairly severe turned-down edge. I confirmed this when I masked off 1/4 inches of the primary using a piece of cardboard. Slightly smaller aperture, but planetary images are much improved. Disappointing, but hey, the price was right! In any event, the loss of aperture from 200 to 188mm should not be noticable. Someday I might get a new mirror, but it's working quite well for now.

DSOs are really good. With a dark sky all messier galaxies can be viewed with some showing detail. M51 is spectacular! Globulars resolve into stars using my Meade 9.7mm Plossl. The Crab nebula - always a difficult target for me was quite obvious using a 15mm Orion Expanse EP. Also quite bright, although little detail could be seen. M42 is stunning, filling the entire 1 degree FOV of the 15mm Orion Expanse. wispy detail abounds!
