I have always coveted a Celestron C5 and finally got one. It is sturdy, well made, lifetime warranty and comes with a padded case for dragging around in the field. The only flaw, and it is not good, is the pathetic finderscope. The finder has a fixed focus and mine is set somewhere beyond infinity so nothing will ever be in focus. The finder mount is not the almost standard dovetail. The screw spacing matches nothing. So you need to get a universal dovetail base and a real finderscope. Ironically, my much cheaper Celestron C90 has a good focusable finder with a dovetail base. Go figure.

I recently bought this spotting scope and have been very impressed. I purchased it for combined terrestrial and astronomical use. Here are some considerations and observations. Since I wanted to be able to use this for astronomy as well, I purchased a star diagonal at the time of purchase. I purchased the Heavy Duty Alt-Az Mount as well. This set up is fine. The mount is lightweight enough to be easily moved around. Good for terrestrial viewing and good enough for astronomical viewing, although it is difficult to see stars high in the sky. Please note that this scope is the same optical tube as the Celestron Omni 127 XLT. At B&H, they sell the Omni 127 with the equatorial mount at a very favorable price. So, an alternative to consider would be to purchase the Omni ... MoreI recently bought this spotting scope and have been very impressed. I purchased it for combined terrestrial and astronomical use.

So, an alternative to consider would be to purchase the Omni 127 and then buy the 45 degree diagonal and alt-az mount if desired. This is more economical than buying the C5 and the CG-4 EQ mount afterwards. Also, mounting the scope on the alt-az mount is done by screwing the OTA to the mount. Since the OTA comes with a dovetail, it might be nice to find a Vixen clamp so you can just slide the OTA onto the mount. All said, very happy with this product.

I use the C5 for visual and imaging astronomy. I already own a Nexstar 8SE and wanted something smaller with the same type of capabilities that I could use on the Nexstar mount, an AstroTrac mount and a manual az/alt mount for travel purposes. The C5 fit the bill and I am very pleased with its visual and imaging performance. Already having a larger SCT, I know about the pros and cons of this type of design, so I'm not surprised by anything. It can share accessories with 8SE without the need for new accessory purchase. At 6 pounds, it is a nice fit for the AstroTrac mount. If you want visual capabilities between 50 and 150 (for most seeing conditions, this lightweight, highly portable scope meets the requirement.

For my usage, it is an all around excellent purchase at an excellent price.

Originally I looked into a high quality spotting scope but their costs were way more than what I wanted to spend. Then I saw this and thought I'd give it a try. Am I glad I did. Works very well for my needs with the added bonus of Celestial observation as well (adding a 2xBarlow a quarter moon will fill the eyepiece and you've never seen it with such details, add a moon filter or you'll blind yourself from the high light gathering). I was able to add brackets for holding my cell phone and a camera for "digi-scoping" adding my zoom capabilities to an already well made telescope. Whether shooting at the range, bird watching or observing the universe this is a great beginning, well made scope at a very responsible price. The only con is there's no quick focus knob so ...

The only con is there's no quick focus knob so you'll crank about 30 full turns from high to low but once zeroed in it's quite crisp.
A great all round scope that can be used out of the box for both land spotting and star gazing. Comes with a good quality padded carry case and was very easy to set up and align with low power aiming scope. Clear uniform image and I can't wait to try it with my SLR camera - just need a couple of accessories. And I loved the B&H service - 3 business days from store to rural Australia via FedEx. Impressive.
The optics are great. However, there are several functional usage issues that make this too problematic to serve as my go-to spotting scope for birding. I like the side mounted sighting scope to align the main scope with my subject matter of interest. However, the alignment screws are too easily turned out of alignment, there is no way to lock them in.My biggest complaint is that the screw mounting system for attaching a prism and objective lens is simply terrible. It is just not possible to tighten the lens enough so that the lens or prism doesn't wobble. They consistently work loose. May not be an issue for simple stationary or astronomy use, but for an active birder, it is a disappointing fail. Digiscoping is nearly impossible. I have considered drilling my own ...

I have considered drilling my own holes and installing my own tightening system. Overall, it is a fair value at this price point, but it could be so much better.
This is the 2nd C5 I have owned. I sold the first one by mistake and had to order another one! The scope is very lightweight. With my diagonal, eyepiece and finderscope it weighs a total of less than 7 lbs.Imaging is crystal clear and focus works great. Highly recommend it.
I have been through a heap of Spotters to watch the Humpback Whales migrate along the coastline from my home in Australia. When you spot whales you only have a few seconds to line them up and depending on the weather it can be a grey on grey background or beautiful water colour. The key is a large aperture Spotting Scope which gathers maximum light and can handle a magnification of at least 40X to see them up to the horizon from shore. I have tested and bought budget and high quality 65mm,and 80mm refractors, and 90 mm and 100mm Maksutov Cassegrains over the years. They all work ok in close but push them out wide to their limits and their smaller light gathering results in a muddy image, plus they can't handle the magnification. The C5 wins against them all.

Clear bright optics, and a usable sight scope all in a compact package with a 45 degree viewing image. The included eyepiece works fine and you can always buy more to increase the magnification if needed. While portable the C5 needs a solid tripod to keep it rock steady. Also buy the c5 dew shield to protect against stray light. The handy padded carry case gives a great protection package. Hope this review helps others get the right gear for Whale Spotting.
The scope arrived and immediately saw that the Celestron labels were upside down when on tripod. As the labels are put on the tube pre assembly it was apparent the tube had been assembled 180 degree out of where it should have been prior to the mounting plate and Finderscope being attached. B&H were 100% with the exchange with another one which arrived speedily to Australia and appears OK but at time of review untested. Celestron are made in China where it would appear quality control failed to pick up on this one. Had bought the scope for a trip away but as it was returned for exchange it was not unfortunately available for that. Very dissapointing. Contacted Celestron who said that the scope should be alright and would send out new stickers to put their branding ...

Lets in a lot of light with strong magnification in a compact size. I wish the finder scope could be moved. I use this for terrestrial photography with a DSLR mounted to the back. I also wish there was a better method for a direct camera mount and large sensors could have vignetting. Fine tuning focus at a distance can also require some trial and error.
