This telescope can be collimated easily by eye, if you want to collimate with a laser, you'll have to remove the corrective lens in the focuser tube. 2) The finder scope is unusable. While I agree, it's not the best finder scope out there and lining it up with the telescope can take a long time but, it is possible with time and patients. (note: it is a scope and not a finder, the image is reversed in the finder). 3) I can't see anything out of this thing. You need to collimate the scope and line up the finder scope, the instructions are in the manual for eye collimation (tip: back the focuser tube all the way out when you collimate, doing this will let you see both the secondary mirror and the primary, also note, this went through shipping and if it arrived with all the mirrors aligned and ready to go, get a power ball ticket because you'd be the luckiest person on the planet. 4) The Barlow is useless. Please google and youtube what a barlow is and how to use them, it's not a true lens and once you find out its true purpose, it'll make more sense. 5) The 4mm lens is useless. See my comment on the barlow, using the barlow with the 4mm will tame things a bit, also, get a lens and filter kit with a 15mm and a 9mm lens. One last comment on this issue is, do not try to push the telescope into position with the clutches locked, use the controls on the tripod to position the scope, if you need to make big adjustments, loosen the clutches (should be OK because your telescope is balanced) position the scope to the general area of viewing, lock the clutches and use the controls to fine tune."
"I later bought the Celestron 24mm to 8mm zoom eyepiece, which allows me to zoom in without changing eyepiece, and it works very well on the smaller 76mm telescope, but again blurry images on this one. I decided to order a Celestron 1.25" collimation eyepiece ($30), which can be useful in aligning the optics (the two mirrors) in reflectors like this one. The reason is that Polaris is faint, and every time you move a mirror by a tiny bit (as explained in the Celestron instruction) the star just darts out of view in the eyepiece. Lastly, I ditched all the Celestron recommendations on day and night collimation (using either the celestron collimation eyepiece or the "ring pattern" for out of focus point sources) and did instead the "EYE-DOCTOR TEST" : I wanted to see how sharp I can get this one, when there is no wind, no shake, no atmospherics, no moving planet, no mist etc. With this method (which I seemingly invented, as it is not described anywhere in the instructions nor on the Celestron site) I was finally able to adjust (by very small increments) the three screws on the secondary mirror till I FINALLY got a nice sharp picture of the writing on the letter. To avoid any further issues due to my previous messing around, I first screwed in the secondary mirror (by loosening up the three alignment screws, and pulling in the secondary mirror all the way in until it barely touches the mount), and later pulled out the primary mirror as well(by pulling out all six screws until the whole unit comes out, then reinserting the mirror after making sure the secondary was pointing the right way, straight to the back). Then, using the Celestron collimation eyepiece with its crosshair, I carefully adjusted the secondary and primary orientations (three screws for each mirror) until all the crosshairs overlapped perfectly. In other words, the crosshair in the eyepiece has to overlap perfectly with its reflection through mirrors 1 and 2, and back to the eyepiece. I found (April 2014) that the best way to collimate this (Bird-Jones or catadioptric design)telescope and get nice sharp images is to remove the focusing lens at the bottom of the focusing tube (takes 10 mins), align the secondary and primary mirrors with an inexpensive LASER collimator (mine is an LK1 $30 from seben dot com, takes another 10 mins to do this part), put the corrector lens back in and reinsert the focusing tube (don't touch the lens with your hands, takes around 5 mins). The secondary (smaller, flat) mirror is oval-shape and mounted right under the focusing tube, held in place by three (outside)-plus-one (center) screws. Now put a focusing cap (just an eyepiece cap with a small 1mm hole in the center) at the (top) end of the focusing tube. Then make absolutely sure (after you take again very carefully the correcting lens out of the focusing tube) that the inside of the focusing tube and the secondary mirror, as viewed through the focuser, are perfectly concentric when you view them through the hole in the cap. That is, the secondary mirror has to be perfectly centered when viewed from the top of the focusing tube. After this is done, make also sure that the tilt on the secondary mirror is such that you can see the center of the primary mirror (on mine I put a black pen mark at the dead center). Now re-align the secondary and primary mirrors with a laser (in my case), with the cap with a hole, or a cheshire eyepiece."
"The instruction manual is weak in this regard and Celestron really should update it to help getting this telescope aligned. If you visit various astronomy forums and ask about this scope, most people will tell you to avoid it because of the time you will be spending collimating it. After you spent time collimating it, then the views are pretty good for the price you pay. I could see the 2 main bands on Jupiter and the moons, the rings of Saturn, but struggled to see the Cassini division. This is the benefits with using an EQ mount where you will only need to turn one knob to keep your object in view."
The Celestron 21035 Travel Scope 70 is a compact 70mm refractor telescope optimized for portability and convenience. The Travel Scope 70 uses a number of plastic components to keep the cost and weight down, including a plastic focuser and plastic lens shade, but the all glass lenses deliver beautiful views of backyard birds during the daytime and lovely views of the Moon and stars at night. The Travel Scope 70 offers daytime views that compare with more expensive spotting scopes. The tripod included with the Travel Scope 70 is described as a “full size photo tripod”, but I like it best as a table-top tripod with the legs kept short. “TheSkyX – First Light Edition” astronomy software with a 10,000 object database, printable sky maps and 75 enhanced images.

Mount (an additional advantage of this telescope is that it is very light so no heavy duty mount is required... however it needs to be properly aligned and you need to be careful not to touch the camera, telescope or mount when taking a photo to avoid vibration)."

"Great for bird watching in my back yard."
"Quality is very great for the price and its many features."
"Purchased as a gift for my husband fr bird watching."
"These binoculars are really nice!"
"They are a good balance of magnification,wide field of view, and brightness (exit pupil). The higher magnification 10x42 would also be good for these things, but you give up some field of view with the higher magnification. The larger exit pupil makes viewing easier, even in bright daylight, because you can see the full image circle, even if your eyes aren't perfectly lined up behind the eye peices."
"Perfect stocking stuffer for my little boy who loves to go bird watching."
"I could spot the birds just as quickly as the others with these binoculars and I can use the money saved to buy a quality zoom lens for my camera!"

I use it on my Remington 700 ADL in 223 and shoot 600 yards with it No Problem. Well, I am now selling all 3 and just purchased another Nikon Buckmaster II 4-12X. Had I realized this a couple years ago, I would have saved a LOT of Time & Money."

"I'm sure that there are better scopes out there but I think that if you are looking for a good cheap scope that will get the job done, this one will work."

Find Best Price at Amazon"I was a little skeptical purchasing it, but reviews for the ranger 1000 were good, the product warranty was superb and the price was much lower than comparable products so I took a chance and I am glad I did. The unit returned a reading 3 or 4 times out of 5 when ranging the cow. I was far from steady and didn't expect to get a return so I was happily surprised. For this reading I used a very steady rest. As I use the Ranger 1500 under different conditions such as snow and cloudy skies, I will update this review. Normally I would have waited to write this review until I had used the range finder more, but since there are no other reviews, I am giving my initial impressions to help others as they consider purchasing this product. With the limited use I have given it, I am giving the Ranger 1500 two thumbs way up. UPDATE 2/6/16. I have had the opportunity to use the Ranger 1500 some more and here is what I have found: With the sun almost directly overhead with a very thin overcast layer, I was able to range a deer at 561 yards in a snow covered field. At that point he came back to the house so I don't know how much further I could have obtained a reading on him. While hunting in mid twenty degree weather I continually got a low battery reading and the unit wouldn't give a distance reading."
"Vortex has a sealed waterproof design and comes with lifetime warranty, Leopold has neither. Both use their own flavor of range compensation (Vortex has HCD and Leopold calls theirs DNA) based on angle but the Leopold adds an additional function of being able to load BDC based on your ammo using an on board table. Both the Leopold 1000i and the Ranger 1000 are made there and from the looks of the packaging and documentation of both, i would not be shocked if they both came from the same factory. If people who are harping about finding one made in USA or Europe then look elsewhere and subsequently look forward to a much higher price point. I find the Leopold easier to use overall, ranges faster, feels slightly more compact, and the fit and finish seems nicer even tho it does not claim to be water proof. The vortex is a sealed coin slot screw but the Leopold uses a flimsy lever twist latch which feels like it might break one day."
"Excellent and easy to use."
"Also, I love the Vortex has a great warrantly."
"this is a product from a serious company that is always behind their products!!!"
"Amazing Product and works better than anything I have ever used."
"Fantastic quality, glass is crystal clear, reading very precise."
"The red display makes the yardage easy to read in lower light conditions."

Find Best Price at Amazon"I was able to snake this thing up there and see everything that I was doing with my hand, and also lay under the car in a comfortable position while I watched what I was doing on my phone. Most of us are carrying around super high quality video monitors in our pockets, so I decided to give this device a try. Also those more expensive units have the cable connected to the screen which is usually mounted to some kind of handle. I have a magnet attached to the back of my phone and it just stuck right up to the pan on the bottom of the transmission. As to durability, I have only had it a week or so and it's holding up so far, although I can envision some problems over time with repeated flexing of the cable. The view you get with it is just like with your phone camera, meaning if you rotate the scope clockwise, the image will also turn which can be disorienting. I got the camera in the right orientation and then bent a "W" shape in the cable a few feet back from the end of the scope. The app allows you to show a mirror image of what you are scoping and you can get rid of the icons on the screen so they don't interfere with what you are trying to look at with the camera. Pros: Price, image quality for live video, stills and captured video, long cable length, WiFi connectivity. Cons: Cheap WiFi box, barebones app, resolution not really changeable."
"I bought this inspection camera for my Dillon XL650 bullet press to be able to inspect brass bullet cartridges while reloading them."
"Really impressed with the Depstech Wifi Endiscope."
"This is tough thing to rate as I have no experience with other competitors but I believe it was a good value and I have used it a few times with mixed results. The tip would work easier if one of the screw on pieces was conical so it would move around obstructions instead of jamming. I found it difficult to get proper depth of field for most exploring projects but it was fine if you knew what you were looking for and about where it should be."
"I'm not dinging it for that thought because of the low price, if I need more battery life than that's probably an endoscope in a different price range."
"When my husband was changing a filter on my car, he accidentally dropped a screw into the abyss and used this to find it (never would've found it otherwise)."
"The image produced by the camera is quite clear and sharp, and the colors are pretty accurate."

This is easily compensated for by bracing against a solid object or using the tripod (provided). All of my friends, a pretty loathsome lot to begin with, have to be frisked before they leave the after being within arm's reach of the Polaris. It would be easy to say I need new friends, but this product would tempt anybody to lust after it."

Find Best Price at Amazon"I was looking for a monocular that stows easily for day trips and canoeing. If you don't want to lug a full size set of binoculars, but still want to view wildlife, concerts, or mountain vistas, I think you will be happy with the Grip Scope. While on a cruise just for fun I help the Grip Scope up to my cell phone and took some shots. You are not going to get a perfect picture every time, balancing the cell phone and Roxant together, but what you can get with the Grip Scope is soooo cool."
"The optics seem to be high quality and the wide field of view makes the image less jumpy and brighter than the smaller 1/2 priced Roxant mini-scope. It's still useful for the indoor pistol range at 25 feet or checking on archery scores, but if you want it for shooting longer distances, just spring for the more expensive 30-60x scopes made for this purpose."
"From the reviews I read by other users, it holds its own in the field and I'm not worried about just tossing it in my pack and having it remain intact. I am trained to work with crews in an effort to control and fight wild fires as they occur across the country. Although I have not had the chance to use this scope in the field yet, I have high hopes for its helpfulness."
"I have used this while hiking and at my house as I live next to a field that has foxes, owls, rabbits and birds for my viewing pleasure. I find it easier to use than several of my binoculars and I have discovered that I like using one eye to view through a scope."
"After reading and watching several positive reviews on spotting scope websites and YouTube, I purchased this economical Roxant High Definition Grip Scope."
