Meade 114EQ-DH4 4.5" Equatorial Starfinder Reflecting Telescope Review

Meade 114EQ-DH4 4.5 Equatorial Starfinder Reflecting Telescope
Average Reviews:

First off I bought this scope used with the intention of reviewing it, and of course using it. The short version: If you looking for a telescope that will give you good views of the planets, and beyond, look elsewhere unless you want to spend extra on better eye pieces and in the long run spend even more on a new focuser, and better finder scope.
First things first, and I must say "Shame on you Meade for selling a decent scope with trash eye pieces!" I lost allot of respect for Meade after buying this scope. The eye pieces that come with the Meade 114EQ are just plain trash and offer very faint and terrible views of even the closet of planets. Not to mention they are .965", instead of the more common 1.25" eye pieces that come with 95% of today's telescopes. However all is not lost! If you call Meade Customer support they will send you out a "FREE" 1.25" adapter (Feeling a little guilty?). The first night I took this scope out was one very clear night, and I thought for sure that I would have at least been able to see Jupiter clearly. Sadly the only thing I ended up seeing was a white blob no larger then a pencil eraser - even with the 4mm eye piece. For a 4.5" scope (114mm) I should have been able to make out some texture. I have other 4.5" scopes and believe me, I can see allot more. After receiving the adapter from Meade the scope did perform close to other scopes in it's range but not it was still not quite up to par but did perform a little better with some decent eye pieces.
Another downfall is the focuser. Not only is it made of cheap plastic but it will also wear out quite easily. Now I understand that mine was used, but the teeth where almost gone. An indication that in time you will need to upgrade and or repair the focuser.
The finder scope is "OK" but still could be allot better. It is also made of cheap plastic, and I am constantly re-aligning it every time I take this scope out - it is often times way off.
The mount is steady untill I take the magnification beyond 100x. However filling the legs with play sand made a big difference, but was still shakey.
I was unable to try out the starfind motor as it was burned out! This could have been due to mistreatment by the previous owner, but then again it maybe it was not.
Overall I still gave the scope 3 stars because it did perform well enough with the 1.25" EPs. But if your looking for a first scope, look elsewhere as this is not the one for you, and is simply a waste of money. Meade does produce quite a few quality scopes however this is just not one of them. As a rule of thumb, never buy a departement store telescope! This one was sold at SamsClub and Costco for $230-$300. You could get a really decent telescope for that kind of money, and enjoy it for years to come.
In closing I have since upgraded this poor little telescope with new optics, focuser, finder scope, mount, and even a fresh coat of paint. It now performs, and even outperforms some of my other 4.5" telescopes. With work, it has potential. If you can find it cheap ($50-$70) it might be worth your time if you don't mind a few upgrades. Total cost of upgrades: $127 = A really nice scope. But by itself? No thank you.

The Meade 114EQ-DH4 4.5-inch Equatorial Starfinder Reflecting Telescope is one of the finest telescope values available anywhere. The Meade optical system includes a superb, hand-figured parabolic primary mirror constructed from low-expansion, fine-annealed Pyrex glass. The mirror meets the theoretical limit of resolution for its aperture and is matched with an elliptical flat secondary mirror of appropriate minor axis. This high-quality construction maximizes performance and is sure to deliver crisp, clear images of your favorite celestial bodies.
This telescope can be used manually to view distant street signs, mountains, trees and other structures. For the beginner, the manual observation is an excellent way to associate yourself with the telescope. However, the biggest benefit of the Starfinder telescope is the electronic motor drive system. This awesome feature allows you to track celestial bodies and move your telescope with a small handbox remote control. Once you answer a series of questions about your location, the handbox will help you find and track your favorite celestial bodies. The motor can operate at seven different speeds, so you'll be able to track almost anything in the sky with a simple press of a button.
With fine construction, built to detailed specifications, and empowering features like the electronic Starfinder motor system, the 114EQ-DH4 is an outstanding telescope for the amateur astronomer.
What's in the Box 114EQ-DH4 4.5-inch reflecting telescope, tripod, 3x Barlow lens, eyepieces, Starfinder motor and handbox, and battery pack.

Pharos Trips and Pics Photo Linked Portable GPS Unit Review

Pharos Trips and Pics Photo Linked Portable GPS Unit
Average Reviews:

(More customer reviews)
I bought Pharos Trips and Pics and downloaded new software from Pharos' web site. The Trips & Pics is a great travel gadget and digital camera add-on. It recorded my trips and geotagged my photos offline by using the time stamp of the photos. Its GPS was surprisingly sensitive; it even recorded my positions while I was eating and taking family pictures in a restaurant. The software is easy to use. I chose Microsoft Virtual Earth to view my photos, and replay my trip. It ran smoothly. The new Trips & Pics software also supports EXIF, Flickr and GPX. I will carry it with me when I go to Olympic in Beijing. Oh, it will be nice if the company can offer extra battery even though the device can last the whole day after fully charged.

Bushnell North Star GoTo 525mm x 3" Motorized Reflector Telescope Review

Bushnell North Star GoTo 525mm x 3 Motorized Reflector Telescope
Average Reviews:

(More customer reviews)
I've got the "non-talking" version of this scope, but I thought I'd post this here, too, since everything else is the same...
Everything bad you've read in the other reviews is all 100% true. From the lack of tracking, poor go-to (because it doesn't keep the time after you've set it), to the way over exaggerated magnification claims, shaky mount-- all true.
I've had one of these scopes for about 4-5 years (got it as a gift). I used it once or twice but couldn't do anything but look at the moon with it. It went in the attic (where most cheap scopes end up) after a short time...
Then I gave it to my sister (she kept it when I moved-- I was going to throw it away). She gave it back after about a year because she couldn't get it to focus. Only useful for the moon she says (couldn't get the computer to work at all-- her fault there-- read on).
Since that time, however, I learned a lot about telescopes in general. So when I got it back, I figured out why it wouldn't focus with the included 4mm eyepiece or the supplied 3x barlow. It was WAY out of collimation. Collimation wasn't even mentioned in the manual at all. They assume it is always in collimation. If a scope gets out of collimation it is useless so it is strange not to put it in the manual at all.
So I take out the primary mirror and mark the center spot with a red sharpie (you need to mark the center of the primary mirror for collimation-- this one doesn't come pre-marked). I put it back in and use a cheshire eyepiece (used for collimation) to line up the optics. Now I knew why there were no instructions on collimating. This thing is almost impossible to collimate! The secondary mirror basically falls out when you loosen any ONE of the set screws! Anyway after about an hour and fifteen minutes I got it in very good collimation.
However, even in good collimation, the 4mm eyepiece will not come into a sharp focus and NOTHING in the 3x barlow will come to focus AT ALL. This is definitely due to very, very poor quality of the supplied eyepieces. I've tried other eyepieces which make this scope perform much better so I know it is the eyepieces. The 3x barlow is 100% useless and it is also 100% plastic (I think it even has a plastic lens). The *only* reason the barlow is in the box is so they can advertise 525x magnification (700mm/4mm * 3 for the barlow = 525x). But the useful magnification for any scope maxes out around 60x the aperture (in inches). In this scope's case that is 180x.
The computer works like it is supposed to (except it doesn't keep the time once you enter it which makes it pretty useless). The problem with the computer and "go-to" in general is the user has to know a bit about the sky before it is useful because you have to line up the scope manually on two stars to set the computer. The novice probably can't do this properly. Note, too, that the second star must be found fairly quickly after the first or the settings won't be very accurate (hard, again, for the novice). The most useful part of the computer is using the direction arrows to manually keep an object in view since they slew the scope at a fairly slow rate.
So, the user should know a bit about the night sky before attempting to ever use ANY go-to system.
First of all, the best way to do that is to buy NightWatch: A Practical Guide to Viewing the Universe (Spiralbound) by Terence Dickinson. That'll get you oriented in the night sky and give a good starting point.
Second, pick up a good starter scope. A good starter Newtonian (same style as this scope) with an object locator (doesn't automatically move the telescope, though) is an Orion SkyQuest XT6. It has twice the aperture of this scope. If you get the XT6 without the intelliscope option it is even cheaper. General rule is buy the bigest aperture scope that your budget allows.
Personally, I don't think you need a go-to at first. It is much more fun to be able to read start charts and star hop your way to find those deep sky objects. Very much like the difference between watching a movie vs. reading the book.

When it comes to stargazing, Bushnell's North Star "go to" reflector telescope is a great choice. From the first-time astronomer to the experienced professional, this telescope and its features will definitely appeal to its users.
With motorized "go to" technology, the telescope's onboard computer is able automatically to find and follow any object from its 20,000 object database. To make viewing easier, the telescope comes with a wide-field red-dot finder scope, which utilizes a red LED projection. This 1x finder scope allows any user to quickly search an area of the sky to quickly find objects.
Other features include 1.25-inch format eyepieces (4mm, 20mm), Barlow lens, and an accessory tray. The package includes the telescope, and an adjustable aluminum tripod. USB and video outputs for quick hook-up to a computer or television also come standard.

McMurdo Fastfind 406 PLB Review

McMurdo Fastfind 406 PLB
Average Reviews:

(More customer reviews)
This is NOT the latest and greatest PLB (Personal Locator Beacon), but it has its place. If you've shopped 406 MHz beacons you know this is WAY cheaper than most others. And there are reasons for that:
1.) No built-in GPS. That means that rescuers will have to locate you using the satellite system's doppler location capability, which is considerably less accurate and much slower to derive a location (could be hours, rather than minutes). But, they should still find you.
2.) An old, bulky and generally "hinky" mechanical construction. If you accidentally deploy the antenna, it is very hard to repack, and damage to the antenna or case are likely. There is a trick to doing it that the importer (Revere) knows, so it can be done, but will require a call to them, or sending it in. When replacing the battery, extreme care is needed to avoid overtightening the case screw. They specify a torque setting in inch-pounds, exceed it and you crack the case, which ruins the water-proof/submersion rating. I could go on, but these are the biggies.
3.) These are old units. So the battery, which has a 5 year shelf life, is probably going to be near expiration. Not a BIG problem, because Overtons includes a free battery certificate from the importer (Revere). For the cost of postage, Revere will send you a free battery as they expire, every 5 years, for life. Mine expired about 6 months after I got it (label on the case has date). I sent in and got a new battery (and a new friend, as "Roy" called and gave me the low-down on battery replacement).
So why do I recommend these? Well, ACR is the current top-of-the-line MFR, now into their 2nd (really 2 1/2 nd) generation, more compact, with much better GPS receivers, etc. But this old war-horse is the unit the Coast Guard chose some years ago when this system first went on-line, it still works, you get "free" batteries for life, and the PRICE IS RIGHT.
BUT MOST IMPORTANT - it is a "back-up" unit for me. I have a SPOT satellite messenger - which I highly recommend. It can send emails or text msgs to your friends indicating your exact location, and saying you are OK, need help, or are in an emergency - in the latter case also calling for search and rescue just like the McMurdo PLB. There are places on the earth that the SPOT won't work (though coverage has improved dramatically in the last year). The SPOT needs a better sky view than a PLB to get out a signal. The SPOT has a yearly subscription fee, not so the PLB. ETC. So, I carry the SPOT for casual travel, to signal friends where I am, and for help or emergencies when out of cell coverage. And if I'm going seriously into nowhere, the PLB comes along too. It has only one function - calling search and rescue - but it is a COMPLETE backup, end-to-end, for this function. That is, it uses different frequencies, different satellites, and a different monitoring and dispatching network.
So, for the man who keeps his pants up with a belt, and suspenders too, but is still on a budget, this old McMurdo unit makes sense as a backup to the much more fun and useful SPOT. And, if you are on a REAL budget and don't want the bells, whistles and annual subscription cost of the SPOT, but still think that a slow rescue sounds a lot better than no rescue, then the McMurdo can still save your a$$ for half or less the $$ of a shiny new PLB from ACR.

Orion SkyQuest XX14i IntelliScope Truss Dobsonian Telescope Review

Orion SkyQuest XX14i IntelliScope Truss Dobsonian Telescope
Average Reviews:

(More customer reviews)
This review is written under the assumption that, for the most part, people looking for a telescope in this price and size range have some prior experience with telescopes in general, and understand the basic terminology I use in the review.
What attracted me to this scope was the large 14" aperture, the portability made possible by the design, and the computer object locator (COL). I own larger and smaller scopes, but generally with Dobsonian style scopes the bigger you go the harder it is to store, assemble, set up and take down when you're done. This design from Orion eliminates a lot of the hassle with larger Dobs, allowing you to gain aperture while still being able to store it in a closet and be able to handle the larger pieces much easier than with most other Dob designs.
That being said, it is not a lightweight. At a minimum you'll be lifting well over 50 pounds (the lower tube assembly), and lowering that piece onto the assembled base is made more difficult by the care you have to use to avoid damaging electronic components that are in the way. One slip and you could easily ruin the COL's ability to function. A number of people don't like the azimuth motion of the scope, there are only three teflon bearing surfaces riding on an Ebony Star ring (a type of laminate) which act as the azimuth bearing, and the movement isn't the smoothest I've felt. Altitude motion is fine, and adjustable. The COL is very simple and operates quite well if you follow the easy instructions for aligning it. Optical quality is quite good, premium aftermarket eyepieces are not wasted on this telescope. Do yourself a favor and get a good laser collimator to align the mirrors, too.
The scope arrives in four boxes, and each box has plenty of small pieces in bags with no extra parts. The instruction manual is well-written, but there are conflicting instructions in some cases which will cause you to scratch your head. You WILL need to have more on the ball than just being able to read and follow directions straight from the manual, a case in point being getting the azimuth encoder spaced properly from the encoder disk in the base (conflicting instructions between the scope manual and an addendum to mounting instructions included with the COL, a problem not solved by a phone call to tech support in my instance). In my case, the cooling fan needed some filing on the mounting holes before it would fit where it's supposed to go also. Most people who have experience with Dobs can easily overcome these problems as minor distractions, but if you have no experience or expect every single piece to fit like a glove you're in for a surprise. The root of most of these problems lies in the fact that the whole shebang comes pretty much straight from China, imported and sold by Orion. The boxes aren't opened to check for missing parts and pieces, perfect fit or problems before they're shipped to you, but Orion usually does an outstanding job of backing their product if somethings wrong.
Overall, it's very hard to find a scope that does as much for so little. Having a 14" scope of any type that you can store in a closet, that has very good optics, and that will find things for you to look at in the night sky was more than anyone could ask for until this telescope came along. Add the shroud and storage cases and you should be happy with this purchase for years to come.

I got this as a gift for my husband. He was absolutely thrilled. The images are very clear and you can tell what's below. The Hotmaps has all the lakes on them so therefore you don't have to buy the expensive maps (if you decide to try a new lake). We did find that the only map it didn't have on it was Lake Wedowee of Alabama. Which we did email the company. To my understanding they are coming out with an update which we can download and take care of that. All in all, we give it a 5 star rating. We love it and it's a perfect gift!
