CNYO Observing Log: Baltimore Woods, 16 March 2013


ABOVE: A 15 sec. exposure from Baltimore Woods. (1) Sirius in Canis Major, (2) Orion, (3) The Hyades (the head of Taurus the Bull), (4) Jupiter, (5) the Pleiades, (6) The Moon.

The sky opened up for a crisp and clear viewing session late in the day after a long spell of heavy cloud cover on Saturday, March 16th. I made it to Baltimore Woods just in time for Bob Piekiel to direct me and my pair of Zhumell 25×100’s to the low-Western Horizon to take in Comet pan-STARRS (C/2011 L4, that is) with a light amber coloring and even a slight vertically-pointing oval that became an obvious tail at low magnification. This view only seemed to get better Sunday night (17th), where the comet was Naked Eye from downtown Syracuse!

2013march16_baltimorewoods_2 has a summary of the current situation on their website (as of 19 March 2013):

A growing number of people are reporting that they can see Comet Pan-STARRS with the naked eye. Best estimates place the magnitude of the comet at +0.2, about twice as bright as a 1st magnitude star. As the comet moves away from the sun, its visibility is improving. Observing tip: Step outside about an hour after sunset and face west. Pinpoint the comet using binoculars. Once you know where to look, put the optics aside and try some naked-eye observing.

By the time pan-STARRS set below the horizon, the sky was quite dark and extremely transparent. Bob and I proceeded to play for an hour with his 11” SCT, new Meade 5000 super- and ultra- wides (24 mm and 40 mm), and my personal favorite, his Collins Image Intensifier (which does exactly what it describes – increasing the brightness of objects in the eyepiece and, in many cases, making observable a dim object you might otherwise completely pass over without knowing it was there – you can see some example images here:

Besides a thoroughly enjoyable conversation about optics, focal reducers, and new eye candy to look for at NEAF, highlights of the observing session included:

Visible Planets

* Jupiter (just to the right of the Hyades, as Taurus exchanges its otherwise brightest left eye (Aldebaran) with Jupiter as its right eye). Having given Jupiter considerable scope time this year already, we checked it mostly just to confirm it was still there.

In Taurus

* Messier 45 – The Pleiades served as an excellent cluster for testing Bob’s new focal reducer (which, basically, increases the field of view). An excellent image showing what the focal reducer does is shown below (from


In Orion

* Messier 42 – The Orion Nebula (without and without enhancement, with the Collins brightening and increasing the extent of the nebulosity). The Orion Nebula is the brightest and most expansive nebula observable from Earth and it sets earlier every day, so we spent considerable time on it before missing it all Spring and Summer.

In Andromeda

* The Andromeda Galaxy (M31) and Messier 32 – The intensifier brought out the presence of the central core of Andromeda but did not significantly enhance detail (specifically the dust lanes and spaces between the spiral arms that one can see in any eyepiece in dark skies). This was likely due to the presence of the Moon nearby in the sky (which can do a significant number to nebula and galaxy detail even when only present as a sliver), but I did learn some more about the intensifier eyepiece (see below). M32 (one of M31’s satellite galaxies) was also bright but featureless.

In Leo

* Messier 65, Messier 66, and NGC 3628 – All three galaxies in The Leo Triplet were excellent in the intensifier (and in the same field of view) despite the Moon. At the first Inner Harbor session, M65 and M66 were just visible (due to the the light pollution around the site) thanks to Ryan Goodson bringing a 16” New Moon Telescope Dobsonian.

In Gemini

* Messier 35 – an open cluster nearly the size of the full Moon, containing a few bright stars and a tight grouping of dimmer ones. The intensifier has a tendency to “haze” a bit around these tight groupings as the pixels on the CCD chip begin to oversaturate.

In Canis Major

* Messier 41 – While observing this open cluster, the over-saturation of the CCD chip became obvious in the form of perfectly circular discs around each of the brightest stars, making each appear to have a well-defined nebula around it (not that these stars need any kind of image enhancement to see clearly in any scope. As you might guess, brighter star = bigger + brighter disc).

In Perseus

Caldwell 14 – The Double Cluster – in the same way that stereotypical night vision goggles give you only shades (or different intensities) of green, the intensifier sacrifices color for “green intensity.” Accordingly, the reds, oranges, and blues in the Double Cluster that make it such an interesting eyepiece object go away, leaving you with just (well, not just) two dense star clusters. This is the best argument for intensifiers being used as tools for galaxy and nebulae hunting.

In Ursa Major

Messier 81 – NGC 3031, Bode’s Galaxy – An excellent sight in the intensifier despite the crescent Moon (which would otherwise make it nearly featureless).

Messier 82 – NGC 3034, Cigar Galaxy – M81’s gravitational neighbor (with M82 being the smaller neighbor and, therefore, more gravitationally influenced by M81). M82 appears to have two distinct cores in the intensifier (that would make it look like two galaxies about to merge). I attribute this double-core view to the intensifier picking up the massive filamentous structure perpendicular to M82’s galactic plane – but should buy my own intensifier to study it in more detail!).

Messier 97 (Own Nebula) + Messier 108 – Admittedly, Bob and I kept passing M108 while trying to find M97 and failed to recognize it as M108 (faint but pleasant in the intensifier). That said, M97 was a very difficult find despite Bob bringing a GOTO scope and, by the time I confirmed to myself that I had it in the field of view, I was under-impressed with the intensifier view (it was barely an object with averted vision, although some part of this could have been the Moon’s presence).

We closed the session around 9:15 p.m. by returning to the Orion Nebula for one last comparison of the intensifier and the Meade 40 mm.

Lessons for the evening: (1) Don’t assume of comets! And, if you observe, report to the group so others know to also not assume! (2) Just because you’re freezing cold doesn’t mean you should stand 1/2 inch from a portable propane heater. At what feels like cryogenic temperatures, your leg goes from 10 F to 150 F before your nerves notice it.

NASA Space Place – Your Daily Dose of Astonishment

Poster’s Note: One of the many under-appreciated aspects of NASA is the extent to which it publishes quality science content for children and Ph.D.’s alike. NASA Space Place has been providing general audience articles for quite some time that are freely available for download and republishing. Your tax dollars help promote science! The following article was provided for reprinting in March, 2013.

Poster’s Note 2:The featured image for this article is that of the Antikythera mechanism, an object that almost defies technological explanation for its age. Its history and operation is worth your considered read! More on this object can be found in its wikipedia article: Antikythera mechanism.

As a person vitally interested in astronomy, you probably have the Astronomy Picture of the Day website at set as favorite link. APOD has been around since practically the beginning of the web. The first APOD appeared unannounced on June 16, 1995. It got 15 hits. The next picture appeared June 20, 1995, and the site has not taken a day off since. Now daily traffic is more like one million hits.

Obviously, someone is responsible for picking, posting, and writing the detailed descriptions for these images. Is it a whole team of people? No. Surprisingly, it is only two men, the same ones who started it and have been doing it ever since.

Robert Nemiroff and Jerry Bonnell shared an office at NASA’s Goddard Space Flight Center in the early-90s, when the term “World Wide Web” was unknown, but a software program called Mosaic could connect to and display specially coded content on other computers. The office mates thought “we should do something with this.”

Thus was conceived the Astronomy Picture of the Day. Now, in addition to the wildly popular English version, over 25 mirror websites in other languages are maintained independently by volunteers. (See for links). An archive of every APOD ever published is at Dr. Nemiroff also maintains a discussion website at

But how does it get done? Do these guys even have day jobs?

Dr. Nemiroff has since moved to Michigan Technological University in Houghton, Michigan, where he is professor of astrophysics, both teaching and doing research. Dr. Bonnell is still with NASA, an astrophysicist with the Compton Gamma Ray Observatory Science Support Center at Goddard. APOD is only a very small part of their responsibilities. They do not collaborate, but rather divide up the calendar, and each picks the image, writes the description, and includes the links for the days on his own list. The files are queued up for posting by a “robot” each day.

They use the same tools they used at the beginning: Raw HTML code written using the vi text editor in Linux. This simple format has now become such a part of the brand that they would upset all the people and websites and mobile apps that link to their feed if they were to change anything at this point.

Where do they find the images? Candidates are volunteered from large and small observatories, space telescopes (like the Hubble and Spitzer), and independent astronomers and astro-photographers. The good doctors receive ten images for every one they publish on APOD. But, as Dr. Nemiroff emphasizes, being picked or not picked is no reflection on the value of the image. Some of the selections are picked for their quirkiness. Some are videos instead of images. Some have nothing to do with astronomy at all, like the astonishing August 21, 2012, video of a replicating DNA molecule.

Among the many mobile apps taking advantage of the APOD feed is Space Place Prime, a NASA magazine that updates daily with the best of NASA. It’s available free (in iOS only at this time) at the Apple Store.

This article was provided by the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.


Caption: The January 20, 2013, Astronomy Picture of the Day is one that might fall into the “quirky” category. The object was found at the bottom of the sea aboard a Greek ship that sank in 80 BCE. It is an Antikythera mechanism, a mechanical computer of an accuracy thought impossible for that era. Its wheels and gears create a portable orrery of the sky that predicts star and planet locations as well as lunar and solar eclipses.
