4.0 out of 5 stars Celestron Ultima 100 ED 9 Dec 2011
By Dave H
I have had this scope for about one month and I am extremely pleased with it. The supplier accidently shipped the lower specification non ED model but quickly corrected their mistake. In a way that was a good thing because it gave me the opportunity to compare both models.
I have to say the difference ED glass makes is amazing. No hint of chromatic abberation (colour fringing) with the ED model.
Images are bright and sharp from 22 to 40 times magnification , above that the image darkens but is still usable unless the daylight is very poor.
The Celestron 100ED blows the socks off more expensive 65mm or 80mm scopes.The only downside is of course the extra size and weight.

3.0 out of 5 stars Ultima 100ED 25 Sep 2010
I use this scope primarily for birdwatching and very occasionally for looking at the moon, stars etc. The soft case supplied with the scope does not have the flexibility to keep it on while in use, which is surprising considering the scope was originally price around the 600 to 700 mark. I corrected this by cutting a flap in the case at the adjusting wheel, which now allows use with the case in place. To my eyes the optics are very sharp and colours excellent. Picking out fine detail in bird feathers is very easy indeed. That is until you go above 30 times magnification, then the light starts to cut down and overall the view gets a bit grainy. At 60 times magnification, it is very difficult to bring items into focus. It can be done, but a fine focus wheel would help. I recently bought a 22 times fixed magnification wide angle eyepiece for 30, from a popular auction site. This has made a significant difference, improving the already good definition and colour. I also own a Bushnell Spacemaster 60mm Scope, fitted with a fixed 22 times magnification wide angle eyepiece, which was also a vast improvement on the supplied zoom eyepiece. The Celestron is a brighter scope, offering more detail, as you would expect. But unless you are planning to be out in low light conditions, where the Celestron is in a different league to the Bushnell, the extra weight, size and cost in my opinion, isn't justified. Overall I am happy with the Celestron, especially now with the fixed eyepiece, but if you are going birding in normal light conditions I would opt for a 60mm or maybe an 80mm scope, as the Celestron's bulk stops me from choosing it first over the Bushnell. However, in low light, it really is excellent.

4.0 out of 5 stars good but 10 Aug 2013
I gave it 4 stars due to the naff carrying bag/ protection , the scopes optics are ok but it needs a fine adjustment wheel not just one big wheel, some quality issues like when you adjust the focus you can see the lens shifting around as though something is out of alignment, the bag is very poor its not strong enough to carry the scope and there no way you can have it on a tripod with folding half of it back over the front body of the lens, you should not have to go out and spend another 40-50 on another stayon bag.

clarity of the optics is great , no dust or marks on the lens unlike a vanguard scope I bought of a reseller who must recondition then and sell them cheap AVOID "[...] they sell customer returns as new.

5.0 out of 5 stars Super bright 11 Jan 2012
Verified Purchase
Excellent value for money. The 100mm ED gives very bright image - specially at about 45mag. Over that, image drops off a bit. Would have liked a proper stay-on case etc.

5.0 out of 5 stars A very fine scope, if you need a scope this good. 15 Feb 2010
By craigb - Published on Amazon.com

Pretty good optics. Clarity suffers a bit at the top 10 power or so, but it is not really fair to compare this to the performance of a $1500+ scope or something. It is leaps and bounds better than the $50 scopes you'd get at a department store, but honestly I am not fully convinced it is vastly superior enough to, say, a $200 or so scope for most people to justify paying double that unless you are doing astronomy or low-light viewing. You're getting a large objective and really good glass, but this is not as important for something like target shooting as the previously mentioned activities.

Be aware though, this thing is huge in every way imaginable. With the eyepiece on, it will need a box with around 23" inches of interior width. I would have liked an included hardcase, but I guess I would rather have a better scope than a lesser scope with a free case for the same price. I found that a surplus military 81mm ammo case ($19) worked fairly well with additional padding and will have enough room for a smaller tripod or other accessories. It's weight is also very high, at around 4.5 lbs. No normal tripod can hope to stabilize this at mid to high powers. Frankly, the tripod you would need to properly utilize the scope at high magnification would probably approach the cost of the scope itself. I have ordered and will try a smaller table tripod that is rated for 11 lbs (camera/astronomy guys all know that the "capacity" and adequate stabilization weights on tripods are not the same and manufacturer numbers tend to be misleadingly high.)
5.0 out of 5 stars Great Scope, Great Price 31 July 2011

My friends with Leopolds and Swarovskis look through my spotting scope and are blown away at how clear it is for the price.

If you are on a budget then this is the perfect scope (and I would say to give it a look even if you aren't on a budget).
