Quote:By the way comparison with the C 80ED was very telling. the image control is much better than the C80ED. It's probably the 3 lens design.

Is it the visable reduction of observable chromatic abberation? The C80ED is very well corrected for the visable reduction of observable chromatic abberation IMO and IME. In my viewing of the Moon with the C80ED,it produces a clean,white image,contrasted with deep blacks in the craters. When the sky is stable,Venus shows a very nice white image as well. Jupiter shows none of it to my eye,either.For this telescope to show "much better" correction in terms of CA,I'd truely be surprised. I've never viewed through an NP-101 or a Tak-78 but those telescopes may well do a more easily noticeable job in controlling this visual abberation if a sharp,highly experienced eye was really looking for it. That wouldn't surprise me. For this Barska telescope to do it,that truely does.

Quote:i am just basing it on what i saw through the C80ED and the Barska.I had a question. Using a 3mm eyepiece and looking at a bright star with the barska, at focus the star showed a fine diffraction ring fairly close to the star. i had not noticed that in other telescopes. is that normal?

One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy.

Quote:Hmm...seems to me like that's not such a great deal while Astronomers without Borders is selling Celestron C80 EDs for $349.Regards,Jim.A terrific deal Jim, mine was shipped to Canada with no shipping charges or brokerage or taxes claimed by Canada revenue, made a nice deal very nice indeed,DA.
I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.

Quote:Hi RichI will be using a G11 for the AP130GT. I use the G11 for my C11 and it handles it fine. I also Have a CG-5. I'm going to see how it works for visual. The G11 is a bit much to transport.
