Ako ti se svidi ono što vidiš vrlo brzo ćeš početi skupljati lovu za bolji i kvalitetan teleskop.

E ako si dobio onda vrijedi.
Potrebno je malo strpljenja za tu montažu ali Mjesec i planete ćeš bez problema moći posmatrati (pokušaj večeras Saturn uloviti). Ima još mnogo zvjezdanih jata, dvostrukih zvijezda i nekoliko maglina koje se mogu vidjeti tim teleskopom.
Jedino ćeš morati naučiti kako kolimirati teleskop jer će biti potrebno povremeno neštelovati ogledala. To nije ništa teško a na ovom teleskopu nećeš često to raditi. Pretpostavljam da su okulari 20mm, 12mm i 4mm.

E to vec nije do njega nego do komsinice.

A blown-up Betelgeuse would be easier to see from my house on the U.S. West Coast, but Eta Carinae annihilating itself would be an incomparably spectacular sight: a super-duper nova that astronomers say could be visible from the Southern Hemisphere during daylight hours.

If we’re lucky, that’ll happen soon, but forecasts for Eta Carinae’s ultimate demise aren’t entirely reliable just yet. The star could blow today or 10,000 years from now, or maybe it already exploded a few thousand years ago and, thanks to its distance from us, we’re still waiting for those photons to arrive on Earth.

Recently, using the Very Large Telescope (VLT) in Chile, scientists took their most detailed look yet at the tempestuous, roiling pair of stars comprising Eta Carinae, a stellar system that could easily be described almost exclusively using superlatives.

Eta Carinae is the brightest, most massive object in our cosmic neighborhood. Its primary star is more than 90 times as massive as the sun, and it shines roughly five million times brighter. Circling that giant is a comparatively unimpressive stellar companion that’s just 30 times the sun’s mass, so enveloped in its partner’s glare that no one knew about it until 1996.

Every five and a half years, the smaller star slingshots around the larger star, creating a whirling nucleus of fury that fuels one of the most chaotic astrophysical environments around: Each star is blasting material into space at speeds that exceed six million miles an hour.

Though the violently dancing stars are only 7,500 light-years away, they’re surrounded by a large, dusty nebula that makes them appear dimmer to earthly eyes.

Epizoda (naslov): SUNČEV SUSTAV
Sunčev sustav naše je najbliže susjedstvo u golemom prostranstvu svemira. S astrofizičarima Dejanom Vinkovićem i Bojanom Vršnakom razgovaramo o tome kako su nastali Sunce i planeti i kada, među njima i naš planet Zemlja. Saznat ćemo što je Sunčev vjetar i može li se jedriti na njemu, zašto Mars ima tako rijetku atmosferu, a Venera toliko gustu, kako znanstvenici "vide" polarnu svjetlost na Jupiteru i koliko su debeli Saturnovi prstenovi te što su patuljasti planeti i koliko ih je dosad otkriveno. Vidjet ćemo i snimke više NASA-inih svemirskih misija u kojima se istražuju Sunce i planeti Sunčevog sustava.
