The Meade 3.5" ETX-90 UHTC Portable Observatory Telescope with Camera Mount is a two-piece B&H Kit including an all-in-one EXT-90 catadioptric telescope and a piggyback camera mounting bracket from JMI Telescopes. The piggyback bracket wraps around the optical tube for secure camera attachment to the ETX-90. The mounting bracket also comes with a counterbalancing weight that offsets the weight of the attached camera. In addition to the Ultra-High Transmission Coated (UHTC) Maksutov-Cassegrain optical tube assembly, the ETX-90 is complete with two Super Plossl eyepieces, a motorized dual-fork altazimuth mount, steel leg tripod, and AutoStar GoTo controller pre-loaded with a 30,000 object database. Combined with the specially configured Piggback camera mount, this Portable Observatory Telescope Kit is a full-featured astrophotography platform for hobbyists and stargazing enthusiasts alike.
Meade ETX-90 AT 3.5"/90mm UHTC Portable Observatory Catadioptric Telescope Kit
The ETX-90 AT 3.5"/90mm UHTC Catadioptric Telescope Kit from Meade is a handsome, compact instrument that's easy to transport and optically pleasant to view with. The telescope itself is less than 10 pounds. Its 3.5" aperture, Maksutov-Cassegrain optics, 1250 mm focal length and f/13.8 focal ratio make it bright enough to deliver satisfying celestial observation with clarity and detail. An entire online community of ETX-90 dedicated users exists, giving tips and sharing images.
The dual-fork altazimuth mount works with the AutoStar #497 controller to deliver GoTo ability for over 30,000 database entries. AutoStar Suite Planetarium Software for PCs allows total computer control of the mount and telescope. A Red-Dot viewfinder accelerates manual prospecting for celestial nuggets of gold. Ultra-High Transmission Coatings (UHTC) with the included Super Plössl 26mm and Super Plössl 9.7mm eyepieces provide increased light transmission and superior optical performance.
An adjustable-height steel leg tripod provides solid support for the mount and scope while the slewing is powered by 6 user-supplied AA batteries or an AC power adapter. A protective carrying case is part of the package. This is a very popular entry level scope for a reason. No, make that a few reasons.
Excellent Maksutov-Cassegrain optics in a very small, ultra-portable package
Built-in flip mirror mechanism; viewing can be done from either 90° or straight through
Autostar controller enables immediate access to its database of over 30,000 celestial objects
Fast and easy alignment procedure; just roughly level scope, point roughly north, and center two bright stars in view
Moon craters by the hundreds, cloud belts on Jupiter, and Saturn's rings are just the beginning of what can be seen with this telescope
JMI Telescopes Piggyback Bracket for the Meade ETX-90 Series Telescopes
The JMI Telescopes Piggyback Camera Mount allows you to attach any camera to the outside of your telescope. This can be done with altazimuth-mount scopes for shorter exposures of up to about 7 minutes, but for sharp pictures free of star drift that go beyond that time you'll need a properly aligned equatorial-mount telescope.
This version for the Meade 90mm ETX series scopes wraps around the optical tube assembly and includes a balancing counterweight that attaches to the telescope.
