This Catalogue is fruit of my passion for both Astronomy and the scientific research. The achievement of my life's last 11 years, it
was a demanding task, both in patience and perseverance. I think nothing of the
like exists today that I know of, being so rich in information for each object, and for so many (more than 10800) celestial wonders. The Catalogue includes, besides thousands of other miscelaneous objects, the
following material:
-1540+ open clusters (oc),
including 139 extragalactic clusters (EGO).
-930+ asterisms (A) or star patterns, many of which could be true open clusters
themselves.
-1270+ galaxies, groups of galaxies and
galaxy clusters (gx, gxg, gxc).
-240 globular clusters (gc).
-205 dark or absorption nebulae (dn), including also Bok and Thackeray
globules.
-190 irregular gaseous nebulae (gn), including emission (gnE) and reflection (gnR) nebulae.
-225 planetary nebulae (pn).
-3500+ binary stars (2), triple (3) or multiple stars (mss), taken from a huge number of catalogs.
-3500+ binary stars (2), triple (3) or multiple stars (mss), taken from a huge number of catalogs.
-2000+ variable stars (vs), including 690+ true carbon stars (cs),
180+ eclipsing variables (evs), and a huge amount of other types as
cepheids (cep), Miras, Wolf-Rayet
stars (WR), the magnificent luminous
blue variables (LBV), and the
peculiar types (pec), among many
others.
-60+
nearby stars included in the SunLikeStar, Habstar, SETI and TFR programs
searching for habitable stellar systems.
- 51+
stellar systems harboring confirmed planets (EPS).
-410+
red stars, including many variables and carbon stars unlisted among the 2000+ variable stars mentioned above.
-22
supernovae remnants (snr) brighter than magnitude 15.
-7
quasars (qsr) brighter than visual (apparent) magnitude 15.5
-7
planets (pl) of the solar
system, and also including dwarf planets like Pluto and Ceres.
-40
moons of the solar system, including of course the Earth's moon.
-105
asteroids from the asteroid belt (within Jupiter’s orbit).
-37 meteor showers and 3 periodic comets that originate some of them.

About a decade ago I purchased my first GOTO telescope, a Meade ETX 125, whose marvelous Autostar
497 built-in database included more than 30000 celestial objects, allowing the
manual addition of other 1000 objects. Only 16 characters of information could
be entered, besides the celestial coordinates, magnitude and constellation
name. Despite the large number of objects listed, this was indeed a paltry amount of information per object.
Moreover, there
were in that database many objects impossible to see from home, due to the poor
urban sky or its southernly latitude.
And absent from that list were many objects I was really interested in
observing. Thus I began to make an additional listing that, by the moment I
sold that telescope, already included about 900 objects, albeit poorly descripted for the
already mentioned Autostar’s limitations.
That was not enough information for observers
who, like myself, want to know the most of the object at the eyepiece, even
with the logical uncertainties inherent to astronomical research. That’s
why along these 10 years I created a
massive catalogue as none in the world
that I may know of. Printable in ~330 landscape A4-sized pages, I described as profusely and completely as posible ~10300 celestial
objects, including the updated celestial
coordinates, the constellation the
object lies in, the type of object, the apparent and
absolute magnitudes, the range of magnitudes in a cluster or variable star, and
a huge amount of other parameters as listed below. The sources had been
innumerable, and only a tiny amount of them are listed below, as it would have
been impossible to enlist them all. Most of the unmentioned sources were just
leaps between different pages and links, while seeking information for a
particular object.
Sometimes,
as with the distance, the spectral type or the diameter of galaxies or
clusters, I found important discrepancies among the sources. In those cases, I
mentioned such discrepancies giving a range, or stating, for instance, “oss 245
Ly” (other source/s state/s 245 light
years).
Further
information included in the catalogue were, for the stars, the SAO /HD /HIP
numbers, the spectral type, B-V index of color, visual and bolometric
luminosity, absolute visual and bolometric luminosities, surface temperature,
age, radial velocity (stated as approaching or receding from us), distance,
etc. If it is a double or multiple system, besides the mentioned information, I
added also details of the companion star/s, as angular separation in
arcseconds, orbital distance in AU, position angle, orbital period,
eccentricity, orbital inclination, name of the discoverer and date,
description of the FOV around the object, etc. In the case of variable stars, I have added the
variable type, range and known period/s of variation, its discoverer and any
other important information. Unfortunately, not all these data had been found for
every object listed, mostly for being unknown at present.
Regarding clusters, galaxies and nebulae, further
information adds name of the discoverer and date, apparent and real size,
class, magnitude and relative position of the brightest star, surface
brightness, visual inclination (radial angle), if the galaxy is edge-on or
face-on, if it lies solitary in the void or belongs to a group or cluster either truly or optically, FOV
description, equipment and conditions needed to observe this object, etc.
At the bottom can be seen screenshots showing its layout.
At the bottom can be seen screenshots showing its layout.
The
catalogue has been written with the aim of selecting objects from it to
observe, and eventually printing this list of chosen objects in an A4
(landscape) page. I have shortened the margins to the outmost, so every line
accepted a maximum of 205 characters. This is one of two reasons of the
catalogue being written in English, as this language requires about 20% less
characters than Spanish to convey the same amount of information. The other is
that the ETX 125 database was already written in English. Most of the times, being in this
language was not enough, so I had to resource to abbreviations to allow even more
information to be included. These are 114, and very easy to use, as they are mostly of standard use (like gc for globular cluster, or gx for galaxy). Only two pairs are more difficult to use, as they have a different meaning if they are capitalized or not: cs (carbon star) and CS (central star of a planetary nebula). sb (surface brightness) and SB (spectroscopic binary).
About 5% of the objects (~500) have purposedly a double entry. This is because there is such a wealth of interesting data available for these objects that a single line could not gather it all, and much information would have been left out. These objects have a (R) or (REP) mark after its name. Similarly, the solar planets and its main moons are the only celestial objects having 3 lines of information each one, for this same reason. Each line is marked 1/3, 2/3 and 3/3.

Each line is marked 1/3, 2/3 and 3/3.
In the case
of the asteroids, all 105 included are visible under dark skies with telescopes
endowed with apertures of 8 inches
The Catalogue includes very accurate and updated (mostly to 2013-2015) celestial coordinates. This
unique feature makes it wonderful for GOTO-telescope users. Non-GOTO users can also
profit from the unprecedentedly huge amount of information it provides. The
updated coordinates were taken from the SkySafary v4 Pro astronomical software,
because all other sources had the Epoch 2000 coordinates. Both RA /Dec
coordinates are expressed as numbers. Thus, Right Ascention 24h 16m 15s is
entered simply as 241615, while Declination
64d 33m 18s South is -643318.
As the
Catalogue has been written in Microsoft Access 2007, it can be easily reordered
according to the column desired. Thus,
it can be ordered alphabetically, or according to the constellation, or
the type of object, or the right ascencion, or to declination. The (range of)
magnitude column is more difficult to reorder, as the program does not choose
from negative or positive magnitude. Besides, in the case the magnitude
information was not available, I have entered in this column information such
as apparent size or minimum equipment needed, when extra room was needed in the
last column to include more interesting observational data about the object.
Magnitude
is espressed generally without commas, and with only one decimal number. Thus, m106 is magnitude 10.6, and m26 is magnitude 2.6. Nevertheless, the fabulous quasar 3C273 has an absolute magnitude of -26.8 (here the comma is needed), and the variable star GS Muscae varies iths brightness from m734 to m755, that is, from magnitude 7.34 to magnitude 7.55 (here 2 decimals are used, for the need of a greater precision).
The first
column, preceding the name of the object, is used to index and select objects.
Afterwards, this column can also be ordered upside down (zz on top), in order
to select what will be observed in the night. All that will not be observed, can this be erased if we want to print the page, In this case, this first
indexer column should be deleted, as if not, the page would not fit into a A4
size. For those people that have not the original program (Microsoft Access,
from the suite Office), I leave it transcripted into Excel 2007, but in this
case the possibility of reordering columns is lost, and only one parameter (name, constellation, object type, AR or Dec) can be chosen to order the
database.
Due to lack
of time, I could not include objects that are not visible in the
whereabouts of Buenos Aires, located at latitude 34*, ruling out all objects further
North than declination 56*N, excepting a very few fascinating objects like the Owl nebula
(M97) or the Double Cluster, though both objects cannot be seen from Buenos
Aires. Logically, the further North it is from declination 40*, the fewer the
objects and the information included.
Its layout includes 8 main columns (plus 4 others I use for personal observing, named X, A, Z and SEEN?) X, A and Z are used to select objects to observe during a particular night, and SEEN? is used to avoid spending time observing something previously seen, unless deserving a new visit.
1) The index column, useful to select items to observe. It has to be cut out if the page is to be printed, after the needed selection has been made, otherwise the page will not easily fit in an A4 page.
2) The object's name column.
3) The constellation column.
4) The object's type (and class) column.
5) The RA (right ascention) column, expressed, as explained, without units and spaces.
6) The DEC (declination) column, also expressed, as explained, without units and spaces.
7) The m/range (magnitude or magnitude range) column. In many times, this column lacks the magnitude information (because it was found nowhere), and in order to free space from the last column (therefore allowing more information to be included in it) I have transferred here some data that was previously elsewhere. In the case of deep sky objects, also the surface brightness, when found, was included in this column.
8) The further information column. This is the very core of the catalogue, because it has a unique wealth of information. Many hundred additional objects are either simply mentioned or partially descripted in this column (if this mentioned or partially descripted object has an entry on its own, it says "see" along with its name). No other listing has such an enormous amount of data, and for that huge number of celestial objects as this, as far as I know

- vsnet.kusastro.kyoto-u.ac.jp/vsnet for information on variable
stars
. http://deepskypedia.com/wiki for general,
miscelaneous information.
-hundreds of observational reports by observers like Steve Coe, Richard Ford,
Iiro Sairanen, Auke Slotegraaf, Jeff Burton, Jaako Saloranta, Laurent Ferrero,
Paul Kemp, Phil Harrington, Carol Botha, Magda Streicher, Tom Polakis, Brian
Skiff, etc.
-Innumerable
(many hundreds) other webpages, mainly visited only once or twice, for a
particular piece of information.
For updated
celestial coordinates (between 2013-2015) and other information I used the SkySafari v4 Pro software, installed on
my Samsung Galaxy Note 3 cellphone.This work consumed about 5,000 hours of my life in its making.
