Celestron NexStar 102 telescope

Have put the telescope together but due to cloudy skies or partly cloudy skies, have been unable to use. Looking forward to breaking it out next week, with a newly purchased Barlow lens, to scan the skies to see what I can see. Great looking telescope.

More than Expected

I purchased this telescope for my daughter and me, It came well packed and to be truthful it was more than I expected. Everything fit well and was well made. I was looking for a telescope that my daughter could use without a lot of setup and this fit the bill. I also purchased the GPS that attaches to the scope and I couldn't be happier with the purchase. Set up the spotting scope on the ground, but haven't had a night that was clear enough to really use the scope as of this time, will add to this review later

My order

While we have not had time to use the new telescope and accessories that we purchased yet I will say that during this difficult time with Covid and everyone having to wait for things your company kept us up-to-date on when our order was coming with emails every so often and did the very best they could. We are pleased with our order and the good customer service. Thank you.

Great telescope if you are more than a beginner..

Great, got a super view of Jupiter and five ok it’s moons plus Saturn the second time viewing. Still learning to perform star alignment. But, looks easy and simple, like aligning the aiming scope.. The only issue I have is the non-magnifying aiming scope.

Nice Little Scope !!

This is a very nice little telescope that has GO TO capability, motorized slewing, and tracking. We leave it set up in our living room and take it out on the back porch almost every night there is a clear sky. This scope is very lightweight and can be easily moved without breaking it down. You just remove the lens tray, fold the tripod legs in, then just pick it up and move it outside ! This makes it very easy to jump outside and view a few objects, then pull it back inside with little effort on a cold winter night. This scope can provide very clear views of star clusters, Jupiter with its tiny star-like moons in the background, Saturn with it's ring, Venus with its phases, Oriens Nebula, etc. The 4 inch lens provides surprisingly crisp views, and has a considerable amount of additional light gathering power over smaller scopes. It works best when limiting magnification to 100 power or so. Using a 6mm eyepiece works great on clear nights, and provides a magnification of 110 times. Even the 32mm eyepiece, with a magnification of only 21 timees, provides great views. You can increase magnification with barlows, etc., but at magnification much higher than 100 or so, you start to loose brightness and clarity. A must is the lens and filter set available from Celestron or other telescope supplier, this will give you a variety of lens and filter combinations to enhance your viewing sessions. A good Fringe-Killer type filter is also a good addition if you wish to view bright objects (Venus, the moon, etc. A moon filter is a MUST - this little telescope gathers a LOT of light when viewing a full moon ! By the way ..... lunar views are very pleasing with this scope, you can really zoom in and see many craters and other features. The GO TO and tracking ability of this scope are plenty good enough for visual viewing, although most of the time I just align by hand, and use the GO TO and hand control to center the object and hold it in the field of view. (it is so lightwieght you can just pick up the whole thing and rotate it to the view you want. One warning ..... this telescope is a battery eater and works best with the optional AC adapter or a Power Tank or similar large battery pack to keep it going all night long. When the batteries get weak, the scope's slewing goes haywire and seems to run off all by itself in high speed !!! After new batteries are installed, the slewing goes back to normal. However, because it uses 8 AA batteries at a time, this can be expensive and most annoying as the batteries always seem to die at the moment you get the best view of the night ! The internal AA batteries will work for a few hours or so, but an AC adapter or larger Power-Tank battery works best. Overall, this has been a great little telescope and we have really enjoyed it. The 4 inch seems to be the perfect size for an intermediate size refractor, it is very easy to move and set up, and will provide many hours of fun viewing for you and your friends.
