“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. 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. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote:At lower mag, as you point out, the differences were all but negligible. But the more I increased the magnification, the softer and more spikey the images became in the dob.

Quote:Thanks for the advice, Jim. I will home in on Vega next time out, though I have already had Altair in the crosshairs and don't recall seeing any false color at all. What I did notice immediately during my initial test drive of my SV ED80 was the difference between reflector and refractor optics. Keeping in mind that this observation is from someone who has been at this for just over a year. Two night ago I was observing with my 6" dob and having a good time, thinking, as I observed, how sharp and clean the stars were in the various open clusters I was sailing through. But when I used the SV ED80 the next night, I instantly understood just how superior refractors are when it comes to serving up absolute pinpoint stars, brilliant clean dots. As I said in an earlier post, the first few minutes with the ED80 converted me into a refractor guy.Thanks for your suggestion here. I always find both information and inspiration in your posts.Doug
