The angled-viewing Regal M2 100ED Spotting Scope from Celestron combines a high-transmission optical path with a nitrogen-filled magnesium-alloy housing to deliver reliable imaging performance at low light and in unforgiving weather conditions. At the core of the Regal M2 are fully multi-coated optics, including BAK4 prisms and an extra-low dispersion (ED) glass objective that minimizes chromatic aberration and maximizes light gathering. Multiple layers of Celestron's proprietary XLT coating on each lens preserve brightness and transmit contrast-rich images to the eyepiece.

This version of the Regal M2 spotting scope includes a 22-67x eyepiece that is ideal for intermediate- to long-range glassing. The broad magnification range, comfortable 20mm eye relief, and twist-up rubber eyecup make this zoom eyepiece well suited for long-duration observations. The scope's standard 1.25" eyepiece mount will accept most astronomy eyepieces, which enables a near-infinite number of optical configurations.

Complementing the image quality and weather-sealed construction of the Regal M2, several features enhance the scope's functionality and observer's user experience. An included T-adapter ring permits DSLR camera mounting to the objective assembly, transforming the 100ED into a high-transmission digiscoping platform. The rotating tripod collar has a 1/4"-20 mounting socket and is detented at multiple positions to provide the observer with alternate viewing orientations. A sliding sunshade, sighting aid, and dual-focus mechanism equip the Regal M2 with the functionality needed for a wide range of outdoor glassing applications.

Celestron M2 Reviews

Go big or go home!

Went birding today and was able to do a back to back comparison between the Celestron and an 80mm Swarovski. Now that's not a fair comparison coz the Celestron in a bigger heavier scope but on the other hand the Swarovski does cost more than twice as much. So visually which was better? Smaller high end or bigger mid range quality? Well it was not even close! Celestron for the win. Day and night brighter and just as crisp. (both scopes were focused on two bald eagles in a tree at 400 yds) The build quality on the Celestron is nice but not as nice as the Swarovski and the Celestron IS bigger and heavier but in my opinion, carrying a scope and a tripod is a pain so what's an extra pound? And if you are going to park it in one place, it's a no brainer unless you want to drop $3k on a 115mm Swarovski which I suspect is even better.

So far its everything it is supposed to be

I'm very happy with this spotting scope, and have used it for wildlife and amateur astronomy. Also note that B&H sells this for the listed retail price; some others state that list price is several hundred dollars higher, and mark it down to $100 to $200 above list.

This Celestron Regal M2 100ED has exceeded my expectations in almost every way. The scope lens has a clarity that rivals many scopes that cost hundreds of dollars more. It's easy to focus; easy to carry; super easy to set up. All the features you want will be in this scope. Fabulous for terrestrial as well as astronomical use.

I went into this knowing almost nothing about scopes, so I called B&H and they pointed me to the Celestron family of scopes. After careful consideration, I bought this one so that my husband and I could actually see the birds we were finding. The first day we took it out we saw a couple of Cinnamon Teals. I was so excited! The scope is very easy to use, well balanced, and just feels solid. After figuring out how the soft shell bag works (it was harder to figure out than the scope), we were set, and took this scope out into the rain and were able to spot lots of birds. I recommend it. It is huge, but not so heavy that a small senior woman can't carry it... My husband adds: this scope, for the price; the quality is excellent. He noticed no vignetting and once understood, the controls are relatively easy to operate, rendering excellent optics for birds when they're not flying.

Exeeeds Expectations

I am an amateur but enthusiastic birder with little Spotting Scope experience. The scope is stored on a tripod with a view to our backyard bird wonderland. Out and about, the scope goes from vehicle to field position within 500' of the vehicle, i.e. we don't lug it around for miles on foot. I typically over-do the research, attempting to eliminate surprises and level-set my expectations. I spent hours looking at scope options, specs, and reviews. The M2 became my baseline for cost/spec'd performance. I particularly appreciated the point/counter-point Reviews by Spike and Eric. Grover also shared some great summary points and hands-on experience, as did others. B&H Spec comparisons were helpful as was consultation with Patrick and David at B&H - Thank you all. I have no regret concerning our purchase of the Regal M2100ED. It quickly opened a new world of detail, excitement, and possibility - e.g. watching a Great Horned Owl shred dinner on a neighbor’s roof,in the moonlight tonight. Awesome!

Good item, pretty decent design flaw.

This scope has two purposes. It looks like it's intended to go back and forth smoothly between those purposes. This does not appear to be the case. The purposes are spotting by eye and taking pictures via a digital SLR. Connecting to an SLR was super smooth. Disconnecting, not so much. The T-Ring with the weight of the SLR froze with one 15 minute connection to a Canon. I spent a LOT of time trying to unfreeze this. Honestly, I consider it a design flaw. The T-ring could just as easily have been a permanent part of the scope and allow the adjustable eye relief house the T-Ring. Admittedly this sounds like a nit. But this does reduce the appeal and flexibility of the use of the product. Now I either have to buy an entire new lens part of deal with an eye relief that is wonky.

Great spotting scope, performs as expected.

This scope compares well to what I remember of the Swarovsky 95mm I rented a few months ago. I have been able to digiscope some young whitetail bucks sparring at fairly close range (1/4 mile). I haven't had a chance to test over 1/2 mile yet, so we will see. I did have some initial problems getting the eyepiece cover off and exposing the T2 threads on the eyepiece. Both are working well after the initial tightness.

Impressive viewing

We use this for birdwatching and other critter viewing. The zoom is excellent and the quality at low or high zoom seems equally excellent. I'll confess I don't have a lot of spotting scope experience to compare to, but, it's quite a step up from binocular viewing, so, if you're using binocs now, you will really enjoy the extra insight these provide.

Yes you could as long as it's 1.25 . However you might get some distortion and darkness. I wouldn't recommend using one. Honestly.
