    • Great Telescope for the Money

THIS REVIEW IS FOR THE NEXSTAR 4SE: I don't normally write reviews for most products but since buying a telescope can be trickey I thought I should help others with this process. First of all if you buy this product you will need to buy a 12v power adapter since the only other option is using AA batteries. If you choose to use batteries you will run into several problems. First of all is the fact that the telescope will run through batteries quickly. I really don't even know why they made batteries an option. Second, batteries do not function well during the cold months. Lastly, batteries do not provide sufficient power for this product to function properly. Now that I have discussed power let me tell you about the scope. This telescope comes with a 25mm lens which is fine but you will want more lenses to enhance your experience. I started by getting a Barlow lens (celestron X-cel Barlow). This is a great Barlow for the money and only has slight dimming. My next purchase will be a X-cel 12mm lens. Back to the telescope. The telescope is very easy to set up and provides great views of Jupiter, the moon, Saturn and deep sky objects. It is easy to focus and lived up to all my expectations. I looked at the nexstar 5 but by the time you buy the accessories you need you will be in the $1000 range. I have never viewed through the Nexstar 5 but based on the reviews I would assume that there is not a significant difference unless you are willing to shell out the $$ for something like the nexstar 6 or 8. The tripod that comes with this telescope is heavy duty and stable. The go to features of this telescope are what makes viewing a pleasure and so easy. You will want to make sure and read the Manuel and watch videos on YouTube to learn how the controller works. Once you have learned how to operate the controller you are well on your way to viewing the night sky. For me this telescope has been life changing because I have always wanted a telescope and just never committed to spending the money. I can tell you that it is money well spent because I have spent a lot of quality time viewing with my son and my friends. You can easily transport this scope wherever you go (outdoors) to make any occasion more interesting. I often find that many people have not viewed the planets through a quality scope and they really appreciate the opportunity it provides. So there it is. I highly reccomend this product. I am including some photos of the moon I took through the lens with my iPhone. I am giving 5 stars because of the quality of the telescope. I can overlook the battery issues due to the bottom line fact that I was impressed with the views of the night sky. ... show more

This is the best quality telescope you can find for the price. Works great and looks super awesome. Not that easy to use but once I got it the siting through the lens is fantastic. You can hook it up to your phone or camera to capture the image you are looking at

    • Expect to spend more money
Style: NexStar 4SE Computerized Telescope
First, let me say that this telescope is great. It has a lot of really cool features. Once it is aligned (more on that later) you can zip to any spot in the sky to look at a lot of cool stuff. As far as I can tell, as a novice, the optics are great. All that being said, I want to give a little warning: expect to spend more money, a lot more money. I haven't marked it down for this, but I want to make it clear for anyone considering it. An experienced user may think this is silly to mention, but, as a total novice, I had no idea what I was getting myself in to. I got this for my dad. He always wanted a telescope. When I saw that I could get this fairly nice one for only $450, I thought it looked like a great deal. I ordered it and it arrived very quickly. When I went to set it up, it was like I hit a wall. When you first start the telescope, it needs to be aligned. There are several available methods for aligning it. The most accurate, I believe, is the three-star align. It seemed easy enough... You find a star and center in the finderscope using a little red LED pointer. Once it is centered in the finderscope, then you center it in the eyepiece and move on to the next star. Easy, right? Here is the first problem: the included finderscope is junk. You have to crouch down to use it and the position of the star changes depending on your angle. I would think the star was centered, then I would move to the telescope eyepiece and all the stars just looked alike. I tried aligning the finderscope using instructions I found on the internet, but it was no good. There was only really one viable solution, a better finderscope. after looking at reviews, I ordered the Orion 9x50 Illuminated Right-Angle CI Finder Scope ($130). After the new finderscope arrived, it quickly became clear that I needed a special bracket so that it would fit the telescope. So, of course, more money spent ($15). The new finderscope made it easier to find the stars and was a lot easier to align, but it didn't eliminate all of the alignment problems. The next issue was getting the star (or planet) aligned in the eyepiece. The only eyepiece included with this scope is the 25mm E-Lux plossl eyepiece. For me, at least, it was impossible to get the object right in the center. My alignments would either fail or when they didn't fail, the alignment would be a bit off. I figured it had to do with not being able to center it properly. To solve this issue, I ordered the Celestron Crossaim Reticle Eyepiece ($68). This is a 20mm eyepiece, I believe, with illuminated crosshairs to make it easier to get it in the center. The new finderscope and eyepiece helped a lot, but my alignments were still failing, a lot. Like probably 75% of the time. The other issue with alignment is the need for accurate time and location information. The handset didn't have any cities particularly close to me. To solve this problem, I ordered the Celestron SkySync GPS ($170). The SkySync definitely made setting the time and location a lot easier, though I am not sure it was worth the money. So, now I am able to get it to align a little easier, though it still fails a lot, which gets frustrating, but at least it is aligning. Getting it to align was only one issue. The other issue is that you don't really see much with the included 25 mm eyepiece. You can get a nice view of the moon, but that's about it. To really explore the sky, more eyepieces are needed. Yay, more money to spend! I ordered the Celestron Accessory Kit ($125). This is actually a pretty good deal. it includes five eyepieces, a 2x barlow magnifier thing and several filters for looking at different planets. I've been able to get some really cool views of Saturn and Jupiter, so far. Everything is almost done. I can align it. I can look at some planets. It's working pretty good. Just one more problem. As I mentioned, I bought this for my dad. He's 75 and can't stand for long periods, which means he can't actually look through the eyepieces. So, another purchase had to be made in order to get the image from the telescope onto the computer for him. I bought a Celestron NexImage 5 MP 5 Solar System Imager with Micron Digital Clarity Technology, Black (93711) ($200). The camera works relatively well to get the image on the screen. It's not great, definitely not as good as looking with the naked eye, but my dad is happy with it, when I can actually get something aligned and in focus. So far, we have gotten some great pictures of the moon and Saturn. So, the telescope was $450. All the stuff I had to buy to actually make it usable was over $700. So, my $450 bargain turned into an $1100 headache. It all works now, but I don't think I would have bought it in the first place if I had realized how much more money I would end up spending. ... show more

    • Great telescope for field use
Style: NexStar 4SE Computerized Telescope
This telescope is perfect for field use. Small enough as a grab and go telescope. Easy to set up in the field since it's not very heavy. Optics are good. This telescope allows great views of the moon and planets as well as bright deep sky objects.

The media could not be loaded. This telescope is truly versatile. It’s suitable to everyone from amateurs to professionals. If you’re interested in using the advanced features you can set up the programming in a matter of minutes and have the telescope simply point to the planet/star you want to view next. And if you’re not interested in going through the set up steps, the hand held remote and laser pointer allows you to simply explore the night sky. You can even use this unit as a table top device and bypass the tripod altogether. But what I love most about this telescope is the ability to connect my Canon camera for some amazing shots of everything from the moon to nature photos (see attached photos and video)! I purchased some additional accessories that included planetary filters and a variety of lenses which allow me to get the most out of this telescope and I love it!! ... show more
