For Sale In CNY – Meade Instruments 8″ LX90 EMC – $1000 or Best Offer

Greetings, fellow astrophiles!

This in from the CNYO Classifieds section. To provide a level of privacy to the seller, please send me an email directly to info@cnyo.org and I’ll make the connecting email to the seller in a reply email.

The Meade 8″ LX90 is the first full capability, computer-controlled 8″ Schmidt-Cassegrain ever offered in its price range. The LX90 Schmidt-Cassegrain is not only a high-resolution visual observing instrument but also is fully qualified for the more advanced areas of astronomy, including long-exposure CCD-imaging and astrophotography.

Special features of the 8″ LX90 include: (a) a die-cast-aluminum double-tine fork mount that rigidly supports the optical tube in all sky orientations; (b) worm gears of 4.9″-diameter on both telescope axes that permit smooth sidereal-rate tracking of celestial objects as well as precise guiding corrections during longexposure imaging; (c) a chromed-steel variable-height tripod that provides all the rigidity required in sensitive field applications — in fact, the same tripod as provided with the Meade 8″ LX200GPS.

Autostar Computer Controller: The LX90’s standard-equipment Autostar controller connects to the telescope’s control panel and permits an incredible array of telescope options:

• Automatic GO TO capability at 6.5°/sec on both axes, simultaneously, to 30,223 database objects, including: 13,235 deep-sky objects sorted by named objects; galaxies; diffuse nebulae; planetary nebulae; star clusters; including the complete Messier, Caldwell, IC, and NGC catalogs; 16,800 stars sorted by name, SAO catalog numbers, double and variable stars; the centroids of the 88 constellations; plus 200 memory locations for user-defined objects. 50 objects in the solar system: 8 major planets from Mercury to Pluto; the Moon; 26 asteroids; 15 comets; 50 Earth satellites, including the International Space Station and Hubble telescope

• Automatic GO TO capability to any object of known RA and Declination. Nine selectable slew speeds: 6.5°/sec, 3°/sec, and 1.5°/sec, plus 128x, 64x, 16x, 8x, 2x, and 1x sidereal. • Control of the telescope through your personal computer, using the RS-232 serial interface. (Requires optional #505 Connector Cable Set.)*

• Fast alignment of the telescope in either equatorial or altazimuth modes using any of three alignment functions, including the Meade-proprietary Easy Align.

• Unlike the hand controllers included with competing 5″ and 8″ SCT’s (and which require disassembly of the telescope electronics for memory upgrade), Autostar is fully upgradeable over the Internet: add the positions of new comets, update the positions of Earth satellites,even add new software as it becomes available.

“Upstate NY Stargazing In September” Article Posted To newyorkupstate.com And syracuse.com

Greetings, fellow astrophiles!

With the summer nearly over and long nights replaced by early school bus mornings, the UNY Stargazing series has returned to its regularly-scheduled monthly publishing.

The latest article in the Upstate NY Stargazing series, “Upstate NY stargazing in September: Cassini’s end and morning planet delights,” has just been posted to newyorkupstate.com and syracuse.com.

The Great American Eclipse for 2017 has come and gone without major reported inconvenience to the cities that ended up hosting large groups. This is good news for Western and Upstate New York, as we will be participants in the observation of totality on April 8, 2024 and have to contend with potential crowds on top of whatever weather early April brings that year. In the meantime, if you still have your eclipse glasses, you can give others an opportunity to enjoy upcoming total eclipses in South America and Asia in 2019. Consider donating your glasses to the great outreach organization Astronomers Without Borders – see the link for all the details.

* It is a busy month for amateur astronomy, with Jupiter getting very close to being un-observable until December (so catch those photons now), Cassini about to take a serious plunge into Saturn, and Mercury, Venus, and Mars doing a wonderful dance in the pre-sunrise skies all month. Try to catch the days shown below (and see the article for more details)!

* The constellation of the month is Draco – and with just one more circumpolar constellation to go, we’re two months away from explaining just what that means!
