    • 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.

Great telescope for a full year now. I brought the 5'' because it fits my budget and is much more portable than the 6" & 8". The telescope arrived in two boxes and was packaged well. It was quite easy to assemble and was straightforward. But the first night when I tested it the red dot finder failed and would not turn on. I contacted product support and they refunded the price of the red dot finder to let me buy another. I think this is reasonable. The telescope was of good quality and was fairly portable in two pieces. I also brought it with the Nex-yz adapter and eyepiece kit. In my opinion, I would not buy the phone adapter and eyepiece kit because I don't use the adapter and eyepiece often. You will pretty much only use the moon filter, 13, 17, and 32mm eyepieces. I also brought a generic LPR filter which helps somewhat in revealing dim objects and filtering out the light pollution . The goto function was really helpful in finding objects especially DSO's. I will use the auto 2 star alignment procedure and manual location settings. This scope was fine for starting astrophotography but exposures can only be limited to 30 seconds maximum. Even though there was a polar alignment option, it was really hard to do since I am living quite close to the equator in Hong Kong and the mount twists into a really weird position when tracking. In the first few months I viewed only from the city, which was a bortle 9 scale. The planets are easy to see, you can see the belts of Jupiter and its moons, and the rings of Saturn easily. If you want a telescope for ONLY the planets, I would recommend some of the scopes without go to like a dobsonian or maktusov because you will be able to see more detail with increased aperture. You don't need go-to because planets are really bright and sometimes the mount will go off track. The Orion Nebula can be seen though only the bright parts. The andromeda galaxy can NOT be seen at all in light polluted places. Later I was able to go out to a better spot ( bortle 5 ) and it was excellent, and I was able to see the double cluster, Orion Nebula and andromeda galaxy a lot better. I would recommend this scope to beginners and people starting astronomy. You can get good results in the middle of the city, but driving to a deep sky site really makes the view impressive. I will not recommend this for astrophotography but instead will recommend scopes with German equatorial mounts. * images are taken with A6000 camera with remote control. ... show more

    • 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
