• Happy Easter

    I will be taking a break this week to celebrate the holiday and regroup from a colder than average winter that largely kept me cooped up inside.

    In the meantime, enjoy some shots from Springtimes past.

  • It’s Time for More Astrophotography

    Although the weather has continued to be worse than normal, I was able to get out in March and image the night sky objects for the Hubble Anniversary Challenge for the month. More about the challenge can be found here.

    This month’s objects contained a few star clusters. The first of which is Messier 67, a lovely open cluster in Cancer. It is also known as M67 or NGC 2682 and is sometimes called the King Cobra Cluster or the Golden Eye Cluster. It was discovered by Johann Gottfried Koehler in 1779. Estimates of its age range between 3.2 and 5 billion years. Distance estimates are likewise varied, but typically are 800–900 parsecs . It is well populated, almost appearing like a globular cluster, and is a paradigm study object in stellar evolution. I find it to be the most interesting looking object of this group.

    M67

    Next up is the well-known Beehive Cluster, also an open cluster in Cancer. It is known as Praesepe (Latin for “manger”, “cot” or “crib”), M44, NGC 2632, or Cr 189. One of the nearest open clusters to Earth, it contains a larger population of stars than other nearby bright open clusters, holding around 1,000 stars. Under dark skies, the Beehive Cluster looks like a small nebulous object to the naked eye, and has been known since ancient times. Classical astronomer Ptolemy described it as a “nebulous mass in the breast of Cancer”. It was among the first objects that Galileo studied with his telescope. The distance to M44 is often cited to be between 160 and 187 parsecs (520–610 light years).

    Age and proper motion coincide with those of the Hyades, suggesting they may share similar origins. Both clusters also contain red giants and white dwarfs, which represent later stages of stellar evolution, along with many main sequence stars.

    M44

    Continuing the theme of open clusters, we continue to Messier 48, also known as NGC 2548. It is in the equatorial constellation of Hydra. It sits near Hydra’s westernmost limit with Monoceros, to the east and slightly south of Hydra’s brightest star, Alphard. This grouping was discovered by Charles Messier in 1771, but there is no cluster precisely where Messier indicated; he made an error, as he did with M47. Credit for discovery is sometimes given instead to Caroline Herschel in 1783.

    M48 is visible to the naked eye under good atmospheric conditions. The cluster is located some 2,500 light-years from the Sun. The age estimated from isochrones is 400±100 million years, while gyrochronology age estimate is 450±50 million yearsr – in good agreement.

    M48

    Finally, we come to Caldwell 48, also known as NGC 2775,. It is a spiral galaxy in the constellation Cancer. It is 67 million light-years away from the Milky Way. It was discovered by William Herschel in 1783. C48 belongs to the Antlia-Hydra Cluster of galaxies and is the most prominent member of the NGC 2775 Group, a small galaxy group in the Virgo Super-cluster, along with the Local Group. Other members of the NGC 2775 Group include NGC 2777 and UGC 4781. This object reminds us that Spring is known as “galaxy season” due to the prevalence of these distant objects in the night sky.

    Due to the distance, this objects appears small in Seestar S50. It is the fuzzy object in the center of the photo.

  • An Unusually Warm Day in March

    I took advantage of some nearly 80 degree weather to go to the Brandywine Museum of Art before my annual pass ran out. While I was having some mushroom soup in the cafe, I noticed a few fisherman in Brandywine Creek. I’m not sure what they were fishing for in March, maybe panfish.

    I made a few stops on the way home to get some RAW files to test new photo editing software that I am using (goodbye Adobe). These shots, as well as the forsythia from last week, are the result.

    First a some exterior shots of the Goshenville historic site on Route 352.

    I am never sure that this is the front of this cute, but unassuming, building.

    This is the blacksmith shop. It was open when I visited another time.

    The next stop was the Thornbury CSA even though it is a bit early for local produce.

    You have to love the sense of humor here.
  • The First Forsythia of Spring

    The forsythia sort of snuck up on me this year. It has been an unusually cold weather with a lot of daytime highs well below average. Here are some views of the herald of spring from around Chester County.

    Some sneaky forsythia to the right. I mostly liked the barn.
  • A Piece of History for Your Next Party

    The Duportail House and Federal Barn lie within the Chesterbrook development in Chester County and date back to colonial times. A history of these properties can be found at https://duportailhouse.com/history/. It is a location that I photograph often, if not for the pages of this blog. The house is on the National Register of Historic Places and can be rented for weddings or other events.

    Here is a look at the property after a January snowfall.

  • The February Hubble Challenge Objects

    My attempts at imaging the February objects for the Hubble Anniversary Challenge were more timely. You can read more about this challenge the Pennsylvania Night Sky page. These images are taken for documentation and learning purposes and are not meant to be great examples of astrophotography. The items below are mostly star clusters, which I find easier to photograph. Three also all contain a connection to the Herschel family.

    The first object is the star cluster Messier 46. It is also known as NGC 2437, and it is an open cluster of stars in the constellation of Puppis. It was discovered by Charles Messier in 1771. It is about 5,000 light-years away from Earth. There are an estimated 500 stars in the cluster, and it is thought to have an estimated age of 251.2 million years old.

    M46 is in the center and skewed about to the right in this photo.

    M46

    Caldwell 58 (aka NGC 2360 or Caroline’s Cluster) is an open cluster in the constellation Canis Major. It was discovered on 26 February 1783 by Caroline Herschel, who described it as a “beautiful cluster of pretty compressed stars near 1/2 degree in diameter”. Her notes were overlooked until her brother William included the cluster in his 1786 catalogue of 1000 clusters and nebulae and acknowledged her as the discoverer.

    C58 or Caroline’s Cluster

    Caldwell 39 is known as the Clown Face Nebula, Lion Nebula or the Eskimo Nebula (aka NGC 2392). It is a bipolar double-shell planetary nebula. It was discovered by astronomer William Herschel in 1787. The formation resembles a person’s head surrounded by a parka hood and is surrounded by gas that composed the outer layers of a Sun-like star. A planetary nebula is an area of cosmic gas and dust formed from the cast-off outer layers of a dying star. Despite their name, planetary nebulae don’t have anything to do with planets.

    C39 lies about 6500 light-years away, and is visible with a small telescope in the constellation of Gemini. The object is the round spot in the center of the image below that is ringed by a faint blue glow.

    C39

    Caldwell 25 (aka NGC 2419 ) is a globular cluster in the constellation Lynx. It was discovered by William Herschel on December 31, 1788. NGC 2419 is at a distance of about 300,000 light years from the Solar System and about the same distance from the Galactic Center.

    C25 bears the nickname “the Intergalactic Wanderer,” which was bestowed when it was once thought not to be in orbit around the Milky Way. Its orbit takes it farther away from the galactic center than the Magellanic Clouds, but it can be considered as part of the Milky Way. It takes three billion years to make one trip around the galaxy.

    The globular cluster is the fuzzy spot in the center of the image.

    I was able to attend the first star party of the season on March 8 and got to view multiple objects (such as the Orion Nebula, Uranus and a crescent phase of Venus) through a variety of telescopes. It was still quite cold in early March but still worth it to get out before daylight savings time set in.

  • Some Orchard-y Goodness

    Barnards Orchards is a fourth generation business in Kennett Square, Chester County, I was able to visit shortly after Christmas and found some great produce and treats to take home.

  • The (late) January Astrophoto Post

    These are my photographs of objects that are part of the Hubble Night Sky Challenge for January. The challenge is coordinated by The Astronomical League in cooperation with NASA. More information about this project cam be found on the Night Sky page.

    First, we have two objects that were not official targets for January but that I think made for better pictures. The Rosette Nebula contains an open cluster known as the Satellite Nebula (NGC 224 or C50), This cluster contains some super bright stars and has been estimated to be less than 5 million years old. The nebula and the star clusters are in the constellation Monoceros.

    NGC 2244

    NGC 2264 gives you two objects for one – the Christmas Tree Cluster and the Cone Nebula. My photo did not pick up any significant nebulosity. I do see a “Christmas” tree with a star on top. Do you? The Christmas Tree star formation consists of young stars obscured by heavy layers of dust clouds. These dust clouds, along with hydrogen and helium are producing luminous new stars. This object is also in Monoceros.

    NGC 2264

    Due to short integration times, lost frames and incoming cloudy weather, the photos below are not all they could be. Hopefully this project will be a learning process for me to improve my astrophotography and visual observing. If you would like to see some beautiful photos of the objects taken by the Hubble Space Telescope, please visit the NASA page here. Do you see the objects in these photos below?

    A popular target for astrophotographers is Orion Nebula, also known as Messier 42, M42, or NGC 1976. It is a diffuse nebula south of Orion’s Belt in the constellation of Orion, and it is known as the middle “star” in the “sword” of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0. I usually need binoculars to see this faint fuzzy patch in Orion. It is 1,344 ± 20 light-years away and is the closest region of massive star formation to Earth.

    M42

    Messier 43 or M43, also known as De Mairan’s Nebula and NGC 1982, is a star-forming nebula also in Orion. It was discovered by the French scientist Jean-Jacques d’Ortous de Mairan some time before 1731, then catalogued by Charles Messier in 1769. It is physically part of the Orion Nebula , separate from the main nebula by a dense lane of dust known as the northeast dark lane. I found this difficult to pick out in my telescope and tried to zoom in on the area designated as M43, but I the small pink blob at the top of this photo is what I’m looking for,

    M43

    NGC 2261 (aka Hubble’s Variable Nebula or Caldwell 46) is a variable nebula located in the constellation Monoceros. The nebula is illuminated by the star R Monocerotis (R Mon), which is not directly visible itself. The first recorded observation of the nebula was by William Herschel on December 26, 1783, being described as considerably bright and ‘fan-shaped’. It has also been described as looking like a small comet and can be variable in appearance due to changes in its apparent brightness. I definitely see the comet-like appearance in this phots. It also looks like a shuttlecock to me.

    C46

    Below is a very faint reddish blob which is a photo of the Crab Nebula (M1, NGC 1952, Taurus A), a supernova remnant and pulsar wind nebula in the constellation of Taurus. The common name comes from a drawing that somewhat resembled a crab with arms produced by William Parsons in 1842 or 1843. The nebula was discovered by English astronomer John Bevis in 1731. It corresponds with a bright supernova observed in 1054 AD by Native American, Japanese, and Arabic stargazers. The supernova was also recorded by Chinese astronomers as a guest star. The nebula was the first astronomical object identified that corresponds with a historically-observed supernova explosion. This is one I will definitely image again with longer exposure integration times.

    M1

    Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.

    M78 is the brightest diffuse reflection nebula of a group of nebulae which belong to the Orion B molecular cloud complex and is about 1,350 light-years distant from Earth. M78 is easily found in small telescopes as a hazy patch and involves two stars of 10th and 11th magnitude. These two B-type stars are responsible for making the cloud of dust in M78 visible by reflecting their light. The nebula came out quite faint and small in my photo and only the main area of nebulosity is visible.

  • A Ramble Through the Township

    A nice summer day called for a trip through some of the more rural areas of my hometown, as well as its center.

    The Diamond Rock Schoolhouse has been featured on this blog before. It is an historic octagonal one-room school which is located at the foot of Diamond Rock Hill in Tredyffrin Township, near Valley Forge National Historic Park. The Diamond Rock Schoolhouse was used as a school between 1818 and 1864. As the population of the area grew during the mid-1800s, the school eventually became too small, and it closed in 1864 when students were reallocated to other nearby schools. After 1864, the old schoolhouse fell into disrepair but was eventually restored in 1909 by the Diamond Rock School Old Pupils Association, a group of former students who saw great value in preserving their former school for future generations.

  • Up, Up and Away

    Valley Forge National Historical Park is home to a model airplane field, a well-groomed grass runway (475 x 125) with a flight line that provides a beautiful view of the park. The field is used by the Valley Forge Signal Seekers (VFSS) Radio Controlled Model Airplane Club. VFSS is one of the largest and oldest clubs of its kind in the United States. Founded in 1959, with over 120 members. The club flies electric, gas, and glow-fuel powered planes and rotorcraft, as well as gliders and turbine powered jets.

    I stopped by a recent event to get some practice shooting fast moving, flying objects, something I don’t get a chance to do very often. We’ll start with a close look at some of the planes on the ground. I am always surprised by how some of these large planes look so much smaller when in flight.

    Now up in the air.

    Love the purple on this one.
    Keeping up with the pros.
    There was some fancy helicopter flying here.
