Product Description

Meade Schmidt Cassegrain optics give you excellent optical performance for the best possible price. For those looking to get the most from their instrument, look no further. Meade uses water white glass with superior light transmission across the entire visible spectrum, unlike inferior standard plate glass used by other telescope manufacturers. Combined with our industry-leading UHTC coatings with 15% better light transmission than standard coatings and oversized, thermally stable Pyrex primary mirrors for optimum light transmission, you get a spectacular viewing experience not available on comparable competitors telescopes. Specifications: Clear Aperture 203mm (8") Focal Length Focal Ratio 2034mm f/10(8") Ultra-High Transmission Coatings (UHTC) Optical Tube Dimensions (dia. x length) 9.1" x 16.75" Viewfinder 8x50 with rear focus Eyepiece 26mm Series 4000 Super Plossl Diagonal 1.25" Telescope Mounting fork-type; double tine fork-type Setting Circle Diameters, RA and Dec.

Awesome Scope 7 Mar 2011
By R. Amato - Published on Amazon.com
Verified Purchase
The optics on this scope are top notch. The Go-To capability works pretty well and alignment in the field is pretty straight forward. There are only a few minor complaints I have.

First, I wish they put the external power jack on the base rather than the fork so that the power cord is not getting pulled around as the scope is slewing to a particular azimuth. The computer has a "Cord Wrap" setting that prevents the fork from turning to much in one direction if you are using an external power supply but that results in some long slews sometimes.

The second is that the computer still uses a serial RS-232 connection when attaching to a PC. Meade really needs to upgrade to USB. Nevertheless, I bought a $15 serial to USB adapter for my PC and I was ready to go - so no big deal.

Overall though, I completely love the scope - especially for the $1,618 I paid for it on Amazon. If you do buy this scope, note two things: 1)The ability to track objects over time work great for observing, but is not accurate enough for astrophotography. I think the more expensive LX200 has a feedback mechanism on its motor drives and is therefore more accurate. 2) This ships from Amazon in TWO boxes despite having ONE tracking number. This freaked me out after I signed for the first box which turned out to only have the tripod - and I was in the system as signing for the whole thing! The scope box arrived the next day.

revision of earlier one star. some problems i found 14 Sep 2013
By Thomas De Voe Worthen - Published on Amazon.com
The go-to system is clumsy to use, but then all of them are. Meade should find some way to allow users to enter RA and Dec numbers for the objects to be viewed. The named star list is fairly brief so you need SAO numbers for stars that have them. If your star has no SAO you are SOL. The messier list is complete; i am not sure about the caldwell list. the list of named galaxies and nebulas is short. So you need the messier or caldwell. Lacking these you are SOL.

The power cord problem mentioned in an earlier review can be a real nightmare. Beware of the cord-wrapping at all times.

The azimuth clutch is hard to squinch down. Hope you have strong fingers. Unless it is squinched anything but slight touch may misalign the scope.

The controller seems rugged, but drop it without its springy cord attached and it will break. buy a leather holder for it and be careful.

The real problem with this telescope is the finder resources. The included finder scope is hard to use, nigh impossible. the carriage for the scope is very difficult to anchor down on an object star. Then temperature changes will loosen it and you gotta repeat a frustrating procedure. It is an inverting scope so unless you are experienced at these tasks, good luck. or buy a different finder.

The nice plossl eyepiece that comes with it has poor eye relief; you will need to buy an accessory. Furthermore it gives a small field at 80x. Hence it is very difficult to locate even a bright star. The moon can be difficult! A nice feature is the search; if the object you requested is not in the field pressing go to again will result in a spiral search that often locates the object for you.

one solution for the narrow field is to buy a reducer lens of the highest power you can get and/or buy a 32mm eyepiece to get a broader field at 50x.

When the scope is properly leveled and aligned to north (not polaris) and the two follow up stars are centered carefully the go to system works well; spot on, in fact. the optics seem very good when the seeing is good; sharp clear images of the moons craters.
