Hi, I looked high ... I looked at Meade.. I looked at Celestion... They were about 30-60% more. And higher... at Pentax. at Redfield even Nikon about double$$ +++ in price. Alas I went low since these had the best reviews found for both birders, very amateur astronomers, and marksmen alike. They are clear and bright to 22 power ( they slowly deteriorate after 22). They focus well even if the field of view is small and getting smaller with magnification. They are easy to handle, for your hands to grip as the weight is not low but neither are they unbalanced or unwieldy. BUT if you have the money to spend and want the best or almost best these are not your lenses. But for the dollar they do what you need to get the job done. Mine is for stadiums to enable me to see what those in the front seats see. To watch nesting birds of prey. They'll work just fine.
I use this zoom eyepiece in my Meade ETX 80 and my Orion XT8i. It has become my default eyepiece. It is not quite as sharp and clear as my Meade or Orion Plossil eyepieces but it is fine for most cases. If I want to spend detailed time on a subject then I might use this to find the best mag then switch to a single mag. But may times this is the only eyepiece I use, sometimes combined with a 2X barlow.
I would hope that this review would help some newer people to the hobby like myself, in finding a great quality first scope. For weeks I have researched a lot of websites and watched many videos on *** concerning choices for a "beginners scope". I had been more impressed with Celestrons offerings than the *** company. I didn't want to spend the money on the *** so I was pleasantly surprised when I stumbled on the Celestron SLT90 goto telescope. Needless to say I found it here on Overstock.com for the best price and ordered it right away. The scope arrived within a week and the first thing I noticed was the packaging was very good. Celestron protected the components very well and the scope itself was a breeze to put together. Within 10 minutes I was up and running and was able to take the scope outside for some terrestrial viewing. The lens quality seems very good as the scope was crystal clear. Alignment of the star pointer was easy so I was ready for the celestial viewing later that evening. About 9PM I started up my Stellarium software and noticed that Mars and Saturn were in close proximity and setting in the southwest sky. (Stellarium is a free open source astronomy program) I did my sky alignment procedure with the handset and star pointer scope and the telescope was ready for what I wanted to see. It was a very simple process as you just point to 3 bright objects as long as they are stars and the scope will be ready to go. I chose the Solar system choices and first up was Saturn. The scope slewed quietly until it stopped. When I looked through the 25MM Kellner eyepiece and BAM...there was the little planet with rings!. The view was small but crystal clear. Almost looked fake it was so clear. Immediately I changed to the other included 10MM eyepiece and the image grew much more in detail and was still very clear but with just a little less brightness. The scope continued to track the planet perfectly and when I changed lenes again to my 6.3MM (that I bought separately)...Saturn was now so magnified, I could see its moon Titan and stars that were beyond Saturn which painted a great view. Needless to say this was a great first impression. Mars was also impressive....but naturally just round but with more color. Now one thing is for sure the go to capability will eat batteries.....I used up 8 in one evening as many hours later the scope was slowing down. I think a must purchase now is that bigger battery pack that you can recharge. I'm not sure how good the scope will be for deep space objects until I go to a darker location than my home. This scope is great for planetary viewing in the suburbs for sure. I have seen the Meade ETX scopes up close and I can tell you this Celestron seems to be much better quality. Im sure the Nextsar SE series is very high quality but this SLT series is not far behind. The tripod you get with the 90 SLT is very study. Its all stainless steel. The eyepieces are Kellner design but have good field of view for planets. The motors in the arm are very quiet compared to Meade.....they are not annoying at all. Overall I think this is really a nice little scope. Even if you get larger aperture scopes in the future, this will be a great portable scope to keep around for many years.
