Shooting Spotting Scope

by AJ, from United States, MN Written on March 22, 2015
I was a little sceptical of if this would meet my needs upon first finding this scope. Optic's plannet 30 day no hassle return policy motivated me to give it a try.

It came well packaged and on time. I set it up initially, and was suprised at the clarity at about 75 yards. I took it out to the local gun range the following week. My test, was shooting a 17HMR at 100 yards. With the lower power eyepiece, I could see the .17" holes in the paper. Trying the higher zoom eyepiece, a standard sized sighting in target filled the entire view. It was significantly darker, but still able to see .17" holes. I was also shooting after work, so dusk was fast approaching.

My next day off work, I stopped out at the range in full sunlight. Again, easy to see 100 yards with the lower power. It was mid afternoon, so mirrage became an issue with the higher magnification eyepiece. I moved out to 200 yards, and mirrage was an issue with the heat coming off the ground. I could still see splatter marks on the metal gong but unable to see bullet holes at that distance with the mirrage. With perfect conditions, I'm sure I'll be able to see larger caliber (.308) at 200 yards. However, it would have to be low humidity, and either early in am or late pm to avoid mirrage.

The only reason I rated it 4 stars, was the tripod is shakey. I found the best approach to adjust, let settle, look, adjust, let settle, look and so forth. I haven't tried adding a hanging weight to it yet, but if you allow it to settl...

Great All Around Telescope

by Pete, from United States, NJ Written on February 27, 2015
I am very happy with this purchase. The Celestron C90 is a great telescope and affordably priced. The quality is very good for both terrestrial and astronomical use. As other reviewers have stated, the tripod is a little flimsy, but I question what weight and bulk telescope would be necessary to assure no movement. Between the play in the mount and the scope itself, there will always be movement.

The two lenses supplied cover terrestrial viewing (39X) and star gazing at 100X. The light weight of the telescope makes it easy to transport and setup.

Spotting stars are a little difficult at first but improves with practice. Once spotted, I have had no problem with focusing....
Pros:
  • Quality
  • Price, well made
  • size, weight, brightness
Cons:
  • None
Best Used for:
  • Terrestrial
  • Astronomy

Great scope, bad tripod.

by Dare C, from United States, CA Written on February 17, 2015
I use the Celestron as a spotting scope primarily. I love the compact design and the backpack it comes with for easy portability. The image is crystal clear and the focus works great. For the price, this really can't be beat. I don't have much experience with spotting scopes so I am not familiar with the more expensive ones. Perhaps someone with a lot more experience could tell me why I should spend $600 - $1200 on the more expensive ones. Right now I just don't see the point. Plus it comes with a tripod.

However the tripod leaves much to be desired. There is just so much slop in it which makes it difficult to zero in on targets several hundred yards away. When you think you have it where you want it and you let go the scope moves like half an inch. Once you get it where you want it do not touch it because it jiggles all over the place.

I used it once to look at the moon. My kids thought it was the coolest thing ever. I must admit so did I. But once again tough to get it just right because of the tripod....

Excellent hybrid spotting scope / telescope for a value price

by Vann, from United States, NC Written on February 3, 2015
I was originally looking for a spotting scope for birdwatching and stumbled upon some reviews for the C90. I was intrigued with the fact that it is a powerful spotting scope but could also be used for casual astronomical viewing. It fills both rolls very well. The scope package is a great deal and includes a tripod, carrying cases for the scope and tripod and two eyepieces. The eyepieces alone make it a good deal. The tripod is only adequate to get you started and I am already planning on a replacement. It is mostly plastic and the movement is very sticky and shaky. The scope itself seems very well built with a metal body and convenient lens and eyepiece covers. The interchangeable eyepieces really make this a versatile scope for both day and night. It came packed very well with super-fast shipping and outstanding customer service from Optics Planet....
Pros:
  • compact size, day and night viewing, well built, interchangeable eyepieces
Cons:
  • None

C90 and tripod review

by Mark Balcom, from United States, CA Written on January 27, 2015
The scope is impressive. I've heard lots of negative comments about the finder scope, but I find it pretty useful. One should align it during the daytime and pick a distant object and center that object in the view of the spotting scope. Then adjust screws on finder scope until crosshairs are centered on object. Take some care in doing this and you will be rewarded with finding objects much more quickly. Good views when looking at birds and wildlife and also at moon, planets and star clusters.

The tripod is pretty bad. I suspect plastic parts will break pretty soon, but it's not very pleasant to use. Worst is when trying to adjust the scope at an upward angle. There is too much play in the attachment. One gets scope aimed, tightens the set screw and the scope slides out of position. For terrestrial use in fairly horizontal position, particularly at low power, it can be used but I suspect you'll be a lot happier with a different tripod. I finally settled on a Vortex Pro GT, but the perfect tripod for combo terrestrial and astro use doesn't exist. Getting good overhead views is the tricky part.

Overall, seems like good entry level scope that can be used for terrestrial and astronomy use....

Great small scope

by Bob, from United States, MA Written on January 24, 2015
A very good deal since mine came with two eye pieces and a tripod. The optics on the telescope are excellent. I was able to see structure on Jupiter! The tripod is probably only useful in use as a spotting scope so you should get a better one for astronomical observations. A great value for the money. Optics Planet delivered on time....
Pros:
  • None
Cons:
  • get better tripod

Celestron C90 spotting scope with tripod

by Steve, from United States, FL Written on January 18, 2015
Bear in mind this is my first spotting scope. I think the Markov C90 is a good value. It's too large and heavy to take in the field, but for range work it's very suitable. It works well for 400 yd plus shots. The finder scope helps a lot for initial acquisition. The focusing is a bit sloppy but the clarity is good once focused. Other reviews had issues with the tripod, however I found it very adequate. The other plus is it works well for star gazing and the photographic attachment makes it useful for bird watching....

When you have to see small objects at a great distance...

by GDarkly, from United States, IL Written on January 13, 2015
As other reviews have stated, the inlcuded tripod should be discarded upon unwrapping. Luckily, I had an old Manfrotto 3205 tripod to which I attached a 391RC2 head before I set out to the Merritt Island National Wildlife Refuge for some bird watching. The only optical equipment I'd used before was a pair of Nikon 10x50 binoculars, and even though they are good quality, the resolution at long distances leaves much to be desired. However, with the Celestron C90 Mak I was able to clearly identify avocets at 600 yards, pintails at 1000 yards, and the delicately nuanced feather colors of roseate spoonbills at 800 yards - all with using the "low power" 32mm eyepiece! I am absolutely amazed at the optical quality and ease of use for such a value-priced spotting scope. I can't wait to take this to another spot closer to home where the trumpeter swans hang out, but at a distance of almost 800-1000 yards from the viewing location. With my binocs I could identify the birds, but with this spotting scope, I'll be able to read their neck bands!...

Super spotting scope

by Ralph the Cat, from United States, FL Written on December 26, 2014
Terrific product for it's price. The clarity and magnification are excellent. It is light weight and easy to operate once the sight scope is adjusted as per the instructions. If you want to view stars and planets a solid tripod costing as much, or more, than the scope would be great for stability! Not made for inclement weather or rough handling. The scope and tripod are light weight and easy to transport into the field....
