The Cosmic Tour Guide, Renee James As a child, I was drawn to it as a tale of longing, grandeur, sadness, and playfulness. I was swept up in its images, whirling galaxies rising above an alien horizon, conceptions of bizarre life forms amid Jupiter’s clouds, billions of years of evolution taking shape against a background of simple music. First was the television show. One episode. Another. Soon I felt a craving for Sunday evening. Then came the book. And when that one’s index began falling out from overuse and abuse, another copy. Then came the soundtrack, a vinyl disk with the minds of musicians from Vangelis to Vivaldi scratched into it. I played it endlessly as I attempted to burn the static images of the book into memory before I forgot which music was supposed to accompany which pictures. And still sehnsucht, made all the more poignant by the closing theme of the last episode. The cosmos called. It beckoned. It taunted. In the days before YouTube and on-demand streaming rentals, I could only wait until PBS aired it again, if ever. Meanwhile, dreams of a galaxy rising over my backyard willow tree kept the connection alive. Carl Sagan’s Cosmos was life-changing. It was what every fable promises. A simple street urchin is, in fact, long-lost royalty. Only it wasn’t a fable. I was connected to the cosmos. Me! The material in my body was ancient and painstakingly forged over billions of years, even if its particular organization was only 11 years old at the time. I was kin to the stars. No – I was even more privileged. My mind could grasp something about them, but they were powerless to understand me. I was, in Sagan’s own words, “a way for the cosmos to know itself.” And I wanted to know more about myself. “If only,” I thought. “I could be like Carl Sagan when I grow up.” Yes, that would be fine. I would become a famous astronomer who understands everything (although I probably would lose the turtlenecks and tweed jackets). I would sail from the shores of this cosmic ocean, exploring – at least mentally – places and processes unknown to most. That would require hard work, a competitive spirit, and sacrifice. But where to go first? Everywhere, of course. The entire cosmos beckoned like a map with giant swaths of unknown regions. “I’m afraid you’ll have to specialize,” came the Voice of Reason. Specialize!? That would mean missing out on so much! Still, I chose a direction and promised myself that I would go farther than anyone had before. With my compass in hand and a slightly heavy heart, I charted a course and headed out to sea. But as I set sail, an odd thing happened. I stole a last look at the shore. Countless people milled around on the beach, digging little moats, sniping at each other, and complaining about their impending sunburns or sandy sandwiches. Few gazed out in awe of that vast expanse of uncharted ocean on the horizon. Few contemplated the wonder of it all. Then it hit me. Carl Sagan was an explorer, to be sure. But he was also a tour guide, taking people to some of the more fantastic places within easy reach of the shore. No matter how many times he showed people the same coral reef, he never seemed to tire of pointing out the colorful fish darting around it. More distant, exotic locales might have been accessible to him had he not spent so much time and energy on local tours, but he was driven to introduce this amazing cosmos to his siblings. Some of them would even be inspired to explore the cosmos in ways Sagan could have hardly imagined. What would he have thought about string theory? What would he say about the fact that we build the esoteric concepts of relativity into everyday GPS devices? How would he have reacted to discoveries of not just a handful, but hundreds of planets, some even potentially suitable for life? My guess is that he would have reveled in these and more. Then he would have set about organizing tours to the newly charted lagoons so that others could share in his wonder. You see, Carl Sagan was not an inspiration because he left everyone behind as he explored the farthest reaches of this universe. He was an inspiration because he invited us to accompany him on his journey, so that we could all get a small glimpse of that great cosmic ocean. And he convinced me that being a cosmic tour guide is as important as exploring a distant corner of the universe. For that I want to say thank you. And happy birthday, Carl.

Shoulders of Giants, Padi Boyd & The Chromatics/AstroCappella, 2008 It was a calm and cloudless night but it was all still a blur A shaking of our Universe was just about to occur It was Summertime... 1609 when Galileo used his telescope for the very first time and he saw mountains and craters on the moon and a Milky Way with thousands of stars and he saw Jupiter, with four tiny moons he was the only man on Earth that night who knew That Copernicus was right come outside with me tonight and I can show you wonders of the world to surprise and delight I've got my telescope with me just wait until you see that on the Shoulders of Giants.... ... we'll see beyond! The world turns round and round now around 400 years have flown since Galileo's telescope first focused the unknown Now we use bigger glass to peer into the past And we're discovering the Universe's secrets at last And there are geysers on Saturn's icy moon and planets circling hundreds of stars while all the Universe expands like a balloon from Galileo's tiny scope we've come so far Galileo was right when he looked out in the night and he discovered wonders of the world to surprise and delight I've got my telescope with me just wait until you see we'll stand on the Shoulders of Giants... And every step follows the one before and opens up a new frontier to explore our 'scopes are dancing in space to see the beauty and grace Oh, Galileo would approve, that's for sure And still for me and you we can join in on this too Just climb up here with me where we'll see more It's a calm and cloudless night come outside with me tonight and I can show you wonders of the world to surprise and delight I've got my telescope with me just wait until you see (oh, wait until you see) we'll stand on the Shoulders of Giants (Galileo knew) That Copernicus was right (Johannes) Come outside with me tonight (Kepler found those) and I can show you wonders of the world (planetary motions on the) to surprise and delight (Shoulders of Giants) I've got my telescope with me (And Isaac) Just wait until you see (Newton found his) we'll stand on the Shoulders of Giants (Universal Laws) (He stood on the Shoulders of Giants...) ...to see beyond!

http://www.youtube.com/watch?v=aWTo_V4ay3o Kepler, John A.Marmie, 2011 Like another science fiction novel curiosity has left me in suspense Could there ever be another planet like Earth Could there ever be another you...I doubt it I keep searchin' for clues that you exist. One more time around and I think I might have found you baby. And I gaze deep inside a our galaxy to a world I've been imagining a glimpse of paradise. Amazing possibilities Could you be...smiling right back at me thru this looking glass in time… A good planet is hard to find. Like the swirls in the sky of a Van Gogh Masterpiece I stare in space and swear he traced distant galaxies Did he close his eyes when he brushed the canvas Did he think of you and smile when he made the planets picture perfect cosmic harmony A starry night reveals your face, I think he might found you baby. Through Kepler’s eyes I see the light and all the world around me...all the worlds around me Mesmerized, hypnotized, I call your name and I call your name and feel your warmth surround me

TO SEEK…, Stuart Atkinson, 2009 Find us worlds, little one, real worlds! Not more bloated bags of garish gas racing crazily ‘round their stars, barely far enough away from their seething surfaces to escape being dragged down into their heart-of-Mordor cores, but worlds where we could talk and walk on springy, surf-soaked, sandy shores and climb great mountains carved from stone… Find us a place Out There where gentle grey rain would wash our faces as we stood on the edge of a sullenly surging ocean, feeling soft-scented winds blowing in from islands oh so far away. Find us a planet where, slowly crouching down, we’d find real rocks scattered ‘round our feet, lying on the dusty ground; a world where cracking such old stones together would sound like snapping bones… But there is no rush. Gaze at the glittering star clouds shining silently ‘tween the Swan and the Lyre as long as you need; we will wait patiently here on the world below until you Know for sure, then you can finally set us free, send our spirits soaring into a sky revealed at last to have been concealing Other Earths from view all along – as many of felt, but could not prove… I grew up knowing just one Earth – the one I stood on when I looked up at The Moon, wondering how it changed its shape; the one I walked on as I made my way Reluctantly to school, wishing I could have remained At home to watch the latest grainy Moonwalk on TV; The one I gazed down on through my bedroom window, Blanketed with unicorn white, pillow soft snow On unbearable, endless Christmas Eves… But if you succeed, the children of today will need To find new words to describe the nature of their sky. Their heavens will contain countless un-named Other Earths, Each one a blue-green sequin spinning round a distant sun, Glinting in the dark galactic night like a fisherman’s fragile fly. And on that wondrous day, when weary travellers from Terra gaze Down upon the surface of the first New Eden to be reached They’ll whisper your name as they stand upon a golden beach On the edge of an alien sea, and, staring at a strange, strange sky, wonder how it must have felt to be alive in that dark and lonely time when just one Earth was known to Man…

Πιάσε το αριστερό του πλευρό, καθώς το δεξί το έχω καπαρώσει εγώ!

Είναι κατάλληλο για αρχάριους. Υπάρχουν άλλοι χάρτες για τους προχωρημένους, όπως η Uranometria ή ο TriAtlas C: http://www.uv.es/jrtorres/triatlas.html

Ναι, μπορείς να χρησιμοποιήσεις το GOTO χειροκίνητα και να εκμεταλλευτείς απλώς το ενσωματωμένο autotracking που σου επιτρέπει να παρατηρείς με άνεση, χωρίς να προσπαθείς να διατηρήσεις το αντικείμενο στο πεδίο. Δεδομένου οτι μιλάμε για ένα χόμπυ, το μυστικό είναι να κάνεις αυτό που σου είναι περισσότερο ευχάριστο. Αν σου δίνει ικανοποίηση η αναζήτηση, όπως δίνει στον κυνηγό η θήρα και στον ψαρά ή αλιεία και δεν ικανοποιούνται απλώς αγοράζοντας αγριογούρουνο από τον χασάπη και τσιπούρες από τον ιχθυέμπορο, τότε επιδώσου στην χειροκίνητη αναζήτηση. Αν είσαι καλοφαγάς και δεν βασανίζεσαι με τον τρόπο που έφθασαν τα εδέσματα στο πιάτο σου, τότε μην ντρέπεσαι να πάρεις GOTO. Δεν έχεις να αποδείξεις τίποτε σε κανέναν, δεν δίνεις εξετάσεις, απλώς διασκεδάζεις. Μπορείς να συνδυάσεις και τα δύο, ανάλογα με τα κέφια σου, ακόμη και με το ίδιο τηλεσκόπιο. Το GOTO πάντως είναι απαραίτητο αν είσαι δεσμώτης της φωτορρύπανσης, όπου τα αστροάλματα γίνονται μαρτύριο, ή στην αστροφωτογραφία όπου δεν θέλεις να ξοδεύεις τον χρόνο σου στην αναζήτηση καθώς έχεις τόσα άλλα πράγματα να κάνεις. Το πρώτο δεν ισχύει για σένα καθώς με έναν πήδο βρίσκεσαι στον μαγευτικό Ζα, το δεύτερο μένει να το αποφασίσεις και όχι βιαστικά, όπως ήδη σε συμβούλεψαν.

The Secret of the Universe, An Ode (By a Western Spinning Dervish), Edward Dowden, 1917 I spin, I spin, around, around, And close my eyes, And let the bile arise From the sacred region of the soul’s Profound ; Then gaze upon the world; how strange! how new ! The earth and heaven are one, The horizon-line is gone, The sky how green ! the land how fair and blue ! Perplexing items fade from my large view, And thought which vexed me with its false and true Is swallowed up in Intuition ; this, This is the sole true mode Of reaching God, And gaining the universal synthesis Which makes All—One ; while fools with peering eyes Dissect, divide, and vainly analyse. So round, and round, and round again ! How the whole globe swells within my brain, The stars inside my lids appear, The murmur of the spheres I hear Throbbing and beating in each ear ; Right in my navel I can feel The centre of the world’s great wheel. Ah peace divine, bliss dear and deep, No stay, no stop, Like any top Whirling with swiftest speed, I sleep. O ye devout ones round me coming, Listen! I think that I am humming ; No utterance of the servile mind With poor chop-logic rules agreeing Here shall ye find, But inarticulate burr of man’s unsundered being. Ah, could we but devise some plan, Some patent jack by which a man Might hold himself ever in harmony With the great whole, and spin perpetually, As all things spin Without, within, As Time spins off into Eternity, And Space into the inane Immensity, And the Finite into God’s Infinity, Spin, spin, spin, spin.

Για φωτογραφίες θα σου πει ο άλλος Κωνσταντίνος. Απλώς να σε ενημερώσω πως τα τηλεσκόπια SCT σε διχάλα (Meade LX90,LX200, Celestron CPC) δεν είναι έτοιμα για φωτογράφηση. Χρειάζονται τουλάχιστον ισημερινή σφήνα, μειωτή εστιακού λόγου και ενδεχομένως αποπεριστροφητή πεδίου. Ενώ μια γερμανική ισημερινή (HEQ5, NEQ6) με ένα κατοπτρικό ή διοπτρικό f/4-f/6 είναι σχεδόν έτοιμα (θέλεις φυσικά φίλτρα, κάμερες και οδήγηση με κάθε τύπο).

Μπορείς να παραγγείλεις αν δεν βρεις στην Σαλονίκη. http://www.superscrews.net/allen-screws.htm Είναι οι 2 αριστερά στην φωτογραφία.

Κώστα, στα χρήματα του Nexstar 6SE που πολλοί ζαχαρώνουν μην γνωρίζοντας πως είναι ακατάλληλο για αστροφωτογράφηση, αυτό το 200/1000 HEQ5 SkyScan PRO πιστεύεις πως είναι η καλύτερη πρόταση; Από τις Meade/ Bresser υπάρχει κάτι ανάλογο;

Θα πας με τον αντάπτορα σε ένα κατάστημα με βίδες και θα δοκιμάσεις ποια ταιριάζει. Υπάρχουν 2 διαμετρήματα. Αν έχει δακτυλόβιδες πάρε, αλλιώς κάνουν οι Allen που έχουν ραβδωτή κεφαλή.
