POI: Caldwell 19
Caldwell 19, also known as The Cocoon Nebula, or IC 5146 is a reflection nebula in the Cygnus constellation area of the sky.
Caldwell 19 is a star forming region. The most massive star known in the cluster is BD+46 3474 (doesn’t appear to be in game under any of it’s other identifiers either such as IC 5146 42, 2MASS J21532885+4715595, or ALS 12039)
Another interesting star in Caldwell 19 is V1578 Cygni which is an example of an HAeBe Star (however in game it is A class, but that isn’t too weird as HAeBe stars eventually will become A or B class, and given Cocoon nebulae’s distance from Earth being about 2500 Ly, what we see today from Earth would be the star as it was in roughly 477 BC, and it may have become main sequence in the intervening 3,786 years between 477 BC and 3309 AD)
So this one isn’t a Caldwell cluster, but it is a prominent cluster in this area of the galaxy nonetheless, and there is a Caldwell cluster to swing by along the way.

S171 7
Main Waypoints Details
Map Reference: Kappa Cassiopeiae
Kappa Cassiopeiae is a runaway blue supergiant star, moving at about 2.5 million miles per hour relative to its neighbors. It’s stellar wind and magnetic field create a bow shock 4 light years ahead of the star, which reaches behind the star as well for a total bow shock length of 12 lightyears.
Additionally is has an unusual spectrum with unusually weak nitrogen lines for a B-class star.
Caldwell 13, also known as NGC 457, as well as The Dragonfly Cluster is an open cluster of stars in the Cassiopeia constellation area of the sky. It is generally an easy target for amateur astronomers as it can be seen with small telescopes even in light-polluted skies.
Two bright stars, Phi Cassiopeia and HD 7902 form the eyes of the dragonfly in this cluster.
Sharpless 171 is an emission region in the larger star forming complex known as NGC 7822. One of the hottest known stars discovered within a kiloparsec of the sun is found here, HIP 139 with a surface temperature over 45,000 Kelvin.

POI: IC 1805 Cluster
The IC 1805 cluster is the cluster which the Heart Nebula is also a part, the brightest part of the cluster is also separately classified as NGC 896 as it was the first part of the cluster to be discovered.
Caldwell 10 also known as NGC 663 is an open cluster in the Cassiopeia area of the sky as seen from Earth. It is considered bright enough to be detected with the naked eye in a dark enough sky. The cluster is of extra interest to astronomers because of the high number of Be class stars, with a total of about 24 discovered in real life.
The optional waypoints for this leg is to simply scout out any stars you can within the cluster. There is a shared discoveries spreadsheet available at this link: https://theexpedition.info/Caldwell1 to keep track of what has already been scouted by the group and what needs to be scouted still. Please make sure to record any progress there as well!
For the next week we will be doing an in-depth survey of the cluster known as Caldwell 14. Discovering, mapping, and bio-scanning anything we can find in there, and logging it to our discoveries spreadsheet for the leg, which can be found: here

POI: Caldwell 1
Caldwell 1, also known as NGC 188 is an open cluster located within the Cepheus constellation areas of the sky as seen from Earth. Being circumpolar as well it is always above the Horizon no matter where you are in the northern hemisphere. It was discovered in 1831 by John Herschel. Among open clusters it has a high number of main sequence stars making it of particular interest to scientists studying those and for potential exoplanets.
It is the first object in the Caldwell catalog made by Sir Patrick Alfred Caldwell-Moore to act as a complement to the Messier catalog. The objects in the Caldwell catalog are ordered by their declination, meaning Caldwell 1 is the most northerly in the sky, and Caldwell 109 being the most southerly.

We will launch our fifth Celebration of Early Astronomy Expedition from this location
Caldwell 41, The Hyades Cluster is the nearest open cluster to our own solar system, and one of the best studied star clusters in existence due to that. From the perspective of Earth, it appears within the constellation Taurus at a similar angle in the sky to Aldebaran, albeit unrelated to Aldebaran otherwise. Four stars of the Hyades, with Tauri constellation Bayer designations Gamma, Delta 1, Epsilon, and Theta form the asterism that is the head of Taurus the Bull. Due to its proximity to our own solar system, the distance to it can be measured using parallax shift of the member stars as we orbit our own sun throughout our year. This leads to the a highly accurate mesaurement of roughly 145 Ly to the center of the cluster. 45 Tauri particularly is on the closer side of the cluster.
Caldwell 99, The Coalsack Nebula is a dark nebula easily visible to the naked eye in the sky as a dark patch obscuring part of the Milky Way’s band. Taking up about 7 degrees of arc in the night sky it is multiple times the size of the apparently size of the moon in our night sky from Earth. In Australian Aboriginal astronomy, it forms the head of the “Emu in the Sky” constellation. It was likewise a bird in Incan astronomy as well, representing a Tinamou.
Caldwell 68, roughly 400 lightyears away from our solar system is one of the nearest star-forming regions to us. It is one part of the larger Corona Australis Molecular Cloud. It was discovered in 1861 by Johann Friedrich Julius Schmidt. It is a variable nebula which shows irregular variations in brightness and shape.
Caldwell 34, also designated as NGC 6960, a nebula in the Cygnus constellation and constitutes the visible portions of the Cygnus Loop. It is the remnants of a supernova. It is also sometimes referred to as the Cirrus Nebula or the Filamentary Nebula.
Additional viewing site suggestion: Veil West Sector PD-S B4-2, puts it nearly in line with Barnard’s Loop for a spectacular view.
Caldwell 20 was discovered by William Herschel in 1786 and located roughly 1800 lightyears from our own solar system it occupies a section of the sky roughly three times the apparent size of a full moon within the constellation Cygnus. It is an emission nebula with the clouds of gas being ionized by a nearby star, causing the gas to glow. The reddish colour is characteristic of hydrogen the dominates Caldwell 20.
Caldwell 2 was discovered by William Herschel in 1788 and located roughly 3500 lightyears from our own solar system in the constellation Cepheus. It can be quite difficult to spot due to having only apparently visual magnitude of 12.3, making it the faintest object in the Caldwell catalog.
“The early 2000s, they were often the speculative setting of early science fiction works. Early imaginings of interstellar travel, first contact with aliens, apocalypses, pandemics, you name it, there was probably a movie or book set in the early 21st century of it. While humanity may not have invented interstellar travel by 2020 as many novels and films purported, they still discovered plenty gems of our galaxy by then.
Lucky for us in 3308 we do have interstellar travel and can visit these gems that humans on Earth in the early 21st century could only dream of visiting. So that is just what we will be setting out to do. This expedition will visit many of the noteworthy celestial objects discovered by the early 21st century, some of which even still are considered noteworthy even today in 3308.
We will be setting off from our faction’s home system Keltim, also known as Gliese 149 to the humans of 2020. From there we will be travelling our route clockwise. Many of the sights on this expedition revisit those featured on earlier CEA expeditions for those that weren’t on those.
Please fill out a sign-up form if you’re coming along! Note: even if you’re not sure yet all your details, the form will give you an edit link once you submit so that you can come back and edit your submission in the future with any changes you make. Just make sure to save your link!
For Celebration of Early Astronomy 5 we are focusing on exploring various Caldwell clusters, and in particular, Caldwell 1, a large cluster high up from the galactic plane that can only be entered and exited using a carrier. The Caldwell catalog was created by Sir Patrick Alfred Caldwell-Moore, a British astronomer and influential TV presenter on the topic of astronomy.
All legs will be one week long with the exception of our week in Caldwell 1, which will be three weeks long in duration. During this time there will be a pair of carriers swapping positions daily

This is where the “At the Eldritch Gate” expedition will be launching from
The first Earth-sized exoplanet to be discovered within the habitable zone of its star. Represented most closely in game by Kepler-186 5. In-game it is not terraformable for whatever reason, but the criteria otherwise matches the closest. The system also contains four other known exoplanets as well represented in-game by bodies 2 (Kepler 186c), 3 (Kepler-186d), 1 (Kepler-186b), and 4 (Kepler-186e).
Kepler-7b is the fourth of the first five exoplanets to be confirmed by the Kepler teelscope. It was the first new discovery by it as the first three were already known exoplanets used to confirm the telescope was working correctly. It is a “Hot Jupiter” orbiting close to its star and measured at a temperature of 1540K. The planet in-game representing this real exoplanet is Kepler-7 1.
This system contains a known exoplanet classified as KOI-3901.01 of roughly 40% the radius of Jupiter. (in game: KOI 3901 5 is the planet in the system matching the criteria)
Of interest to the At the Eldritch Gate expedition in particular is that the planet in question is a gas giant with Ammonia based life, which have the chance to be a green gas giant, so may actually be our giant. Or maybe not, but at the very least it’s an interesting real world planet.
Nicknamed “The Black Widow Pulsar”, PSR B1957+20 aka PSR J1959+2048 is an eclipsing binary millisecond pulsar discovered in 1988 by the Arecibo radio telescope with a rotation period of 1.6ms. It orbits with a companion super-jupiter brown dwarf with orbital period of 9.2 hours when it was discovered. At discovery it was hypothesised that the brown dwarf companion was being destroyed by the powerful outflow of high energy particles from the neutron star’s jet cones. As it is no longer there in 3308 this seems to have held true. It was the first known pulsar with this arrangement and is the namesake of the class of pulars known as spider pulsars. Black widow types having a companion brown dwarf, and redback types having companion red dwarfs.
Chandra X-Ray Telescope has also determined through observations of the system’s bow shock that is has a high speed across the galactic plane in comparison to most stars. Approximately 20 times as fast as our own solar system.
Discovered by the Ginga telescope in April 1988 when it produced an X-ray nova caused by matter falling in from it’s K class companion into the black hole classified as GS 2000+25. In 3308 it is found to also contain some other bodies, including a terrestrial planet with ammonia based life.
First discovered by William Wallace Campbell who noted it’s peculiar hydrogen-rich spectra. It was an at the time uncharted planetary nebula, and a member of the yet to be classified WC subclass of Wolf-Rayet stars. Do note that this system is fairly high from the galactic plane and may be difficult to reach for low jump range ships
We will officially be partaking as a squadron in the upcoming “At the Eldritch Gate” expedition starting on July 10, 2022.

It is a bit different than how CEA was run in that we followed a path. At the Eldritch Gate is more of a large area search, in this case for teh first found green gas giant that was discovered long ago, but the discoverer, not actually knowing what they had didn’t make note of what system it was in.
So Celebration of Early Astronomy, using CMDR NovakDrogo’s carrier will be basecamping and searching in and around waypoint 4: Dehe PP-V d3-22 which is 21,430.63 Ly mostly west and a little bit north-ish from “the bubble”
There is a small selection of real stars as well within 5,000 Ly from the Waypoint 4 system: HD 339279, PSR J2004+3137, PSR J1955+2908, HD 186438, & HD 227959
