Quote:for a newbie like me,who only does visual (no AP),would I be able to tell the difference between the traditional C8 and the EdgeHD 8 ?

Quote:Why would Celestron put a Optical tube like the Edge that was design mostly for astrophotography on a mount that can't do that.Ain't happening.

Quote:Uncle Rod, your equation is missing the personal preference variable. For me, the performance improvement of the EdgeHD was enough to justify replacing my standard SCT. But I understand that it might not be enough of a difference for others.Geoff
Quote:It's not for me. Why not? The reducer problem. So far no reducer has been shown to be fully suitable with these scopes. That means observing and imaging at f/10.
Quote:And the dirty little secret? With the Celestron r/c in place the field in a standard SCT looks very close to that of an HD.
Quote:It's considerably cheaper, and I like THAT, too.

Quote:Quote:Quote:As they say, to each his/her own!As I see it all new Celestron series will be based on the HD scopes from now on Unlikely. Please elaborate. Do you think Celestron will continue to produce standard SCTs as well as EdgeHD SCTs for the foreseeable future, or do you think the EdgeHD is Celestron's version of "New Coke"?Geoff
Quote:I can NOT answer your question as I own 8 and 11 inch REGULAR Scts BUT have looked thru a buddies new 8' Edge a few times...To me as a 100 percent visual observer who honestly does not dwell looking at the stars at the extreme edge of the eyepieces FOV I "personally" do not see the Edge being worth the extra money....BUT BELIEVE Me the edge is better... no ands no ifs nor any butts but a visual observer who uses a Focal reducer combined with a pair of old worn out eyeballs have no desire (READ NEED) to upgrade...Bob G.
Quote:I guess I am somewhat surprised at how many people don't really care about the edge of field performance for visual use.After many years of using refractors, I came to realize that the REAL benefit of refractors was the fact that they tended to have far better off axis performance. I didn't drink the "refrators have better contrast" kool-aid, but every time I looked through refractors with low power naglers in teh diagonal, the view was always amazing. Everything in the field was sharp.The EdgeHD is the first reflecting telescope that I have ever used that provides esentially the same "WOW" feeling when viewing wide, rich fields.I personally think the EdgeHD is sooooo far superrior to the standard SCT that I can no longer tolerate Naglers in a standard SCT. The edge of the field (where there is often a lot of stars that add an great deal of context to the field) truely looks "Refractor Like" in the EdgeHD.Side by side, my EdgeHD gives up very little off axis to my 6" APO when the field is equally as wide. Using it with a 31mm Nagler or a 20mm Nagler is a magnificent experience.So, you like what you like, and if the loss of off axis sharpness doesn't bother you, I get it, but I just wonder WHY it doesn't bother so many people? 70% of all the background stars in a rich field are in the outer half. It just suprises me that so many people are OK with 70% of these stars being badly abberated.Anyway, I personally would never buy another standard SCT again. The EdgeHD made the SCT a scope for the 21st century. The old design was a produce of the mid-20th century when 1.25" Erfles were the widefield eyepeice of the day.So much has changed. And FINALLY, the SCT has caught up to current eyepeice technology.

Quote:I have a new Orion 17mm Stratus eyepiece which has a 68 degree field. The extra eye relief is nice and I really like the eyepiece but I did notice a lack of sharpness at the edges of the field (perhaps 75% of the way from the center) when using my Ultima C8.
