Astronomical Book Review: 'Objects in the Heavens' by Peter Birren

 
When it comes to observing equipment and resources, my watchword has always been portability. Most of my star-gazing, after all, is done either aboard ship using a rich-field telescope or ashore with a grab-and-go Mak. I try to extend this ethos as well to the paraphernalia of observing; when I tote the Astroscan on deck or the 90mm into my backyard I don't care to be burdened-down by large, un-wieldy Star Atlases or heavy reference books.

What I've needed, and sought, for nearly fifty years was an inclusive, powerful guide-book to the northern-hemisphere sky; a single, portable volume that combines the features of a lightweight atlas and descriptive guide to the planets, stars, constellations and deep-sky objects to be observed from my home and from most of the ports I am likely to visit in the course of my long deployments.

It's been a long, hard slog through the years, as I've purchased, tried, and then abandoned many examples of astronomical writing and even software. Either the resource in question was too bulky, too tech-ie, or insufficiently versatile to meet my standard. After all, the book or program in question had to be able to support my observing activities for up to a year, far, far away from my home astronomical library. Essentially, it had to become that library during frequent long sea voyages.

'Objects in the Heavens', referred to hereafter as OITH, is in my opinion that portable, user-friendly resource.


OITH is the product of Peter Birren, a graphic designer based in Illinois. A dedicated amateur astronomer, he started building the database that would become OITH 'way back in the mid-1990s.

He put a lot of thought into the content and layout of this little volume, and it shows.

 
The book is 8.5" by 5.5", spiral-bound and 132 pages--just the right size for a knapsack pocket or eyepiece case--and printed on tough, water-resistant paper (my copy has survived the worst of Virginia's dewiest nights, requiring only a drying-out and pressing between a pair of heavier volumes to restore it to "almost new" condition).

As for what lies between the covers...


The constellation and object maps are the centerpiece of the effort, and display their subjects clearly and concisely. As in many such books I have tried over the years, they feature facing pages with the map to the right and details on the objects displayed to the left. Larger or "busier" constellations tend to occupy two pages while smaller or "less interesting" members of the sky bestiary are given the "thumbnail" treatment.

The amount of information is pretty impressive, and fine-tuned to the binocular or small-to-medium-sized telescope. As noted previously the maps cover constellations and celestial gems down to -45 degrees Declination, and objects to magnitude ten.


But there is much more to be found in this little book. Sections include introductions to star- and constellation-hopping, celestial coordinate systems, Moon information and "thumbnail" daily lunar highlights for a full lunation (above), seasonal constellation maps, information on major meteor showers, a fairly exhaustive listing of website resources, and a handy summary of solar system information (below).


As noted above, I find this book to be pretty-darn perfect for use in my own "minimalist" approach to observing; I've owned a copy of Edition 5 for two years and now have Ed. 6--and every time I go out under the stars I appreciate Mr. Birren's labors that much more. The back-cover "blurb" that OITH is "Informative for the beginner" and "Detailed for the advanced" observer says it all, I think.

OITH is a field book for use at the eyepiece, and I strongly recommend it for anyone who wants to go out under the stars and explore those "Objects in the Heavens".

Keep looking up!

f-stop: Russian Photo-Op

'Severomorsk' conducts helo recovery operations
Frequent readers will know that I have long held a fascination for the ships and aircraft of other navies; the sight of an unfamiliar rig or unknown flag stirs my blood in a way that warships of my own Navy no longer can. I reach for binoculars and begin picking-out details that might lead to an identification, then head for the bridge's copy of 'Janes' Fighting Ships' to search for a match.
Helix '53' takes a good look at Laramie
If I may say so, I'm pretty good at this. I've had quite a bit of practice over nearly four decades at sea, after all.

Here we have a recent encounter here in the Gulf with the Russian destroyer Severomorsk and his* 'Helix' helicopter. This was an easy "I.D.", for though I'd never actually seen one of these 'Udaloy-class' ASW ships before I've spent a lot of time studying the Russian Navy and it's warships, and it is a very distinctive design.
Shorts and a t-shirt...it must be Casual Day in the Russian Navy
Severomorsk passed several miles from Laramie, which was a bit of a disappointment to me as I would have loved to have seen and photographed him more closely, but as a consolation the destroyer's helicopter came quite a bit closer and in fact flew around Laramie for a few minutes. This was quite an enjoyable air-show, as ship and helo exchanged waved greetings and took snapshots of each other.
As you can see, the 'Helix' looks quite different from Western helicopters, but it's counter-rotating rotor system is actually quite efficient, doing away with the balky transmission system and tail-rotor of more familiar rotary-wing aircraft.

Das Vidanya!



* Ships in the Russian Navy are referred to using the male pronoun.

Stars Over The Gulf II

Captain Donnelly meets the "Red Turkey"!
The first Laramie Star Party was a great success! Eleven Shipmates (including the Captain) joined me on the bow to view the Moon, Saturn and the International Space Station passage which just nicked the edge of Luna, making for a spectacular view through the eyepiece!

The skies were clear for the first few hours, and I'm especially impressed by the cooperation of the Skipper and Navigator, who shaped our course to keep the Moon and planets on the port beam (where masts and booms don't interfere with the view) and decreased speed so as to reduce vibration and improve the view through the telescope.

A good time was had by all, and I now have a "go" for future viewing sessions on a not-to-interfere basis with ship's operations. I'm already planning for the next one. I wonder how many of my crewmates have really LOOKED at the Milky Way...

Stars Over The Gulf I

Calm seas and beautiful skies; the dust storms that have masked the heavens for several weeks appear to have moved on. Last night I gathered a few Shipmates on the portside bridge-wing and took them on a naked-eye tour of the visible planets and Milky Way.

At these latitudes (about equal to those of southern Nicaragua or northern Costa Rica) we can see well down into Centaurus to the south while the familiar stars of Ursa Minor (including Polaris, the "north star") are lost in the summer haze to our north. Thus, the central bulge of our galaxy stands high and impressive in the inky sky.

Just a fantastic view!

Tonight--if the weather and seeing conditions hold--I'll take the Astroscan 'scope to my favorite observing location up forrard. I think it's time to introduce some of my friends here to a few deep-sky wonders.

Stay tuned!

In The Sweet Spot

Last night: I was already tired from a long day's work as I carried my Astroscan forward to the Sweet Spot beside the portside boat station--where the ship's engine and generator vibrations are damped-down by a happy coincidence of hull structures and cargo tank placement--and set up for a few hours of stargazing @ sea.

It was an absolutely beautiful night, with only a mild swell to move 'Laramie's hull, a light wind, and those clear, dark skies that can only be found hundreds of miles from the nearest streetlight or 7-Eleven. The kind of sky where the forms of familiar constellations become difficult to discern because of the multitudes of dimmer stars that seem to crowd them out and break up the patterns we grow accustomed to seeing in the heavens.

Seeing and transparency were excellent, and after acclimating my 'scope's optics to the warm, humid Mediterranean air I began to explore.

Open clusters, globulars, planetary nebulae and galaxies presented themselves for inspection; M51, 27, 31, 32, 110, the Coathangar, M13 and 92--all framed in my 40mm and 25mm eyepiece fields like precious jewels and minerals on display. Stars; Hershel's wonderful Garnet, the spooky duo of v (Nu)Draconis, Lyra's Double-Double and so many more...the time flew past as I drank in the light of distant stellar beacons. And as finale; the fuzzy apparition of Comet Giacobini-Zinner, traveling through Cassiopeia, a distinctly elongated blur in my optics.

And, just like that, four hours had passed. If I was tired when I toted my 'scope up to the bows, then I was reeling with exhaustion as I began the climb back to my stateroom and bunk. But I was also drunk with starlight, overpowered by Saturn, Jupiter and Mars, stunned by the vistas revealed by my little telescope as the ship carries me across the surface of the sea and beneath the stars.

Immensities below, infinities above...the word and concept of awe seem to lack sufficient depth and power. To feel the rumble of the engines, hear the rush of water down the sides and the occasional splash of an escorting dolphin, to drink in great draughts of wonder from above...THIS is why I do what I do, and this is why I cannot imagine ever stopping.

 I really do have the best job in the world.
