  • Great telescope for beginners
Style: NexStar 5SE
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

  • Great Telescope for the Money
Style: NexStar 4SE Computerized Telescope
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
