Hey guys

So my brother acquired the celestron regal m2 65ed. At first, I was insanely impressed with it..but when I started using it few more days,  I started to notice def a huge difference in image quality the more magnification you use. My brother seems to think that higher quality scope wouldn't really be all that different in that aspect. (at least not worth $1000, or $1500, etc) I see people raving about the Vortex Razor HD. (I believe around $2000) Any of you used both to decipher how big a difference there is between these two?

Discussing with celestial terms. Quality wise your eyes are on the earth , The Celestron is near the moon and the Vortex will be near Neptune. Smile
Old true adage says, Quality trumps magnification every time.

Folks ain't got a sense of humor no more. They don't laugh they just get sore.

Need to follow the rules. Just hard to determine which set of rules to follow
Now the rules have changed again.

Maybe you misunderstood my question?

I do understand that ultimately you want quality glass/optics, and that's more important than magnification. But my question is, does the higher quality optic have discernible/better quality at the higher magnifications compared to the lower quality scopes? or is it hard to get a great image when you're at 48* etc, with any scope?

I will venture an answer if I am wrong I am sure others will correct me.

The answer is that lower quality optics will have more optical problems as the magnification is increased.

Lets say two optics systems one quality and the the other questionable. At low power both "look good" but as power is increased the questionable one will have resolution, chromatic and other distortions.

Think about what is going on, errors in the optics system are multiplied as magnification is increased. So take two window panes one of optical grade glass the other so so. They might be undistinguishable at first glance or without special tools. But use the same two items in a optical system -- design, lens cutting, glass quality, mechanical assembly, quality testing where the inferior one falls behind at every step so all of its deficiencies are also magnified.

Thanks for giving me an idea of all the different components that would make a difference for the overall quality..but, have you looked at a lower quality scope (ie $500 and then $2000) and FELT/SEEN a huge difference in your opinion in terms of quality? That is what my question gets at. ..especially at higher magnification.

I feel that sometimes people just pay higher because of the brand, but in reality, it's not a huge improvement.

I would say that that under casual use you would not notice much difference between the 500 and 2000 dollar price point. But it would not take all that much of a challenge to show the superiority of the high end unit.

As an example a 600 yard target under quickly changing lighting conditions, storm moving in with heavy clouds and getting very dark very quickly in late afternoon with noticeable increasing haze. Shooter is on the target board, both scopes (spotters) did not notice any splash around target but can't locate new hole in target rings. The high end unit was just barely able to see a hole in the card board backer where there was manufacturer printing (quickly alternating black and white/tan). The bulet hole almost appears to be a trade mark/ copy right mark right a the end of some printing. The lower priced scope was having a hard time even making out the bullet holes in the target and could not tell the difference between the printing and the new hit.
