Quote:Thanks Bob! I have local who has an XLT C8. If I can just make him stop for a while imagening I hope to borrow his scope for a couple of hours to evaluate:-)Unfortuneately I am a rather discriminating observer!/Magnus 57N.

Quote: Quote:I need expensive wide field eypieces to fully enjoy the comafree field. To some degree, you are indeed correct. For visual use, the EdgeHD is at its best with 82 degree AFOV eyepeice (or even 100 degree AFOV types).

Quote:Magnus,If your C8 has very good optics, that quality will have a profound impact on high power detail and contrast. No modern coating can make up for that. Only if the modern sample has similar high quality optics, than the coatings will add a little extra. Make sure you test any new C8 side-side with your old C8 at identical magnifications with identical eyepieces and diagonals. The coatings will do good on very low power views. As soon as you go to 150x and up, the quality of the optics will reveal themselves. Not only in the level of detail, but also in the steadiness of observable detail. Like the better scope has better seeing, while in fact it has better optics under similar seeing.

Quote:I have a mid-90's black tube C8 and I wouldnt trade it for anything other than an EdgeHD (8" vs 8"). Mine compared better than a friends similar model C8 and every bit as good as a brand new dark orange tube 8SE. I might even sell my 10" Meade SCT someday soon and buy the EdgeHD and keep my black tube C8. I like it that much! But I like my Meade too! Maybe I'll keep them both and just buy the EdgeHD! Everbody needs two 8" SCT's and a 10" SCT. Right?

“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:I recommend that you find some one local that has the Newer C8 that you are thinking of purchasing and see for yourself how your old C8 compares in a one to one showdown, directly with that scope using the same eyepiece and same diagonal. It might not be as big a jump as you might be anticipating...Bob
