A chain of galaxies, known as Markarian's Chain, part of the Virgo supercluster, seen over Mt. Lassen, a volcano in California that last erupted in 1914-1917.
The two interacting galaxies making up the pair known as Arp-Madore 608-333 seem to float side by side in this image from the NASA/ESA Hubble Space Telescope. Though they appear serene and unperturbed, the two are subtly warping one another through a mutual gravitational interaction that is disrupting and distorting both galaxies. Hubble’s Advanced Camera for Surveys captured this drawn-out galactic interaction.

NGC 5907/5906 - The Splinter or Knife-edge Galaxy - is another classic edge-on Spiral Galaxy displaying a prominent dust lane that is located 54.5 million light-years away in the constellation of Draco.
I shot this because I thought it would be an interesting comparison to the galaxy NGC 4565, which I recently published.
This was shot over 3 evenings on the nights of 5-29-22, 5-30-22, and 5-31-22.
During this period of time, there were a lot of drifting thin clouds. Since this galaxy is small and my image scale on this shot was a bit on the low side, I had to be very careful to use only the best frames in integration to ensure a sharp and detailed image. While this reduced my total integration, I think it helped with the detail level of the resulting image.
This was shot with my Astro-Physics 130mm f/8.35 APO sitting on an IOptron CEM60 mount, sporting a ZWO ASI260MM-Pro camera.

Roque de Los Muchachos Observatory is one of the largest and most well-equipped astrophysics laboratories in the world. Nestled at the highest point of La Palma, it is in the most idyllic location it can ever have on the island.
The observatory also holds the second-best spot to gaze at the stars in the Northern Hemisphere. It also houses the largest single-aperture telescope. It is not only perfect for viewing the night sky, but also for observing solar phenomenon during the day.
Thanks to the climatic conditions and its unique physical characteristics, the Roque de Los Muchachos has one of the clearest skies on the planet. The location of the island and its climate makes the cloud act as a natural mirror, blocking light pollution from the towns beneath.
A large cloud of ionized gas, IC1396, rising over sand dunes at Death Valley National Park in California. This cloud is huge, over 6 full moons wide, and at least twenty full moons in visual area, but unfortunately too dim to see with the naked eye. Within it is contained the well-known Elephant's Trunk Nebula — can you zoom in and spot the elephant head and trunk?

Caption: MAVEN's Imaging UltraViolet Spectrograph obtained this image of Mars on July 13, 2016, when the planet appeared nearly full when viewed from the highest altitudes in the MAVEN orbit. The ultraviolet colors of the planet have been rendered in false color, to show what we would see with ultraviolet-sensitive eyes. The ultraviolet (UV) view gives several new perspectives on Mars. Valles Marineris, a two-thousand-mile canyon system, appears prominently across the middle of the image as a blue gash. The deep canyon appears blue due to the scattering of ultraviolet light by the atmosphere, so strong that we cannot make out the bottom of the canyon. The greenish cast of the planet as a whole is a combination of the reflection of the surface plus the atmospheric scattering. The three tall Tharsis volcanoes appear near the left edge, dotted by white clouds forming as the winds flow over them. Bright white polar caps appear at both poles, typical for this season, in which there is a transition from southern-hemisphere winter to summer. The magenta-colored region visible at the south pole shows where ozone is absorbing ultraviolet light — the same property of ozone that protects life on Earth from harmful UV radiation. While ozone tends to be destroyed by chemical processes in the winter on Earth, different atmospheric chemistry at Mars caused it to build up in the winter there. A hint of ozone is also visible near the north pole; more will accumulate there as winter is coming. IUVS obtains images of Mars every orbit when the sunlit portion of the planet is visible from high altitude.

Today, NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) mission completed one Mars year of science observations. One Mars year is just under two Earth years.
MAVEN launched on Nov. 18, 2013, and went into orbit around Mars on Sept. 21, 2014. During its time at Mars, MAVEN has answered many questions about the Red Planet.
“Taken together, the MAVEN results tell us that loss of gas from the atmosphere to space has been the major force behind the climate having changed from a warm, wet environment to the cold, dry one that we see today,” said Bruce Jakosky, MAVEN principal investigator, from the University of Colorado in Boulder.
NASA recently declared that MAVEN had achieved mission success during its primary mission. Mission success means that the spacecraft operated as intended, made the expected science measurements, and achieved its proposed science objectives.
NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission.

After a string of 4 clear nights in late March, it's been a long time since we have had a stretch of clear moonless nights. So no astrophotography for me…
In the meantime, I had upgraded one of my astro cameras to a new camera known as the ZWO ASI2600MM-Pro. This is a mono camera based on a new generation of larger APS-C size sensors. It offers much higher resolution, a full 16-bits of dynamic range, outstanding noise characteristics, and a much deeper well capacity (which means I can overexpose bright areas of the image - stars - much more before I saturate the sensor). This was also a bigger and heavier camera and I needed to rework my rig to balance things out. I have been eager to test this out.
Recently I had that chance. Choosing Messier 63 - the Sunflower Galaxy as my target I took over 15 hours of exposures through Luminesce, Red, Green, Blue and Hydrogen-Alpha filters over the nights of May 13th, 14th, 15th, 16th, and 17th. I thought I had clear nights but it turns out that thin clouds passed through on EVERY night - enough cloud to mess-up my exposures but not enough to shut things down. I inspected every single frame and I ended up throwing out 5 HOURS of data due to "Cloud Pollution". I got to tell you - that HURTS.
So about our Target…
I have captured M63 before and I wanted to see what difference I could make with a new camera and a bit more experience under my belt. I am very pleased with the result of my first effort with this camera. Good detail, excellent color.
Located 29.3 Million Light Years away, this is what Wikipedia has to say about M63:
Messier 63 or M63, also known as NGC 5055 or the seldom-used Sunflower Galaxy,[6] is a spiral galaxy in the northern constellation of Canes Venatici with approximately 400 billion stars.[7] M63 was first discovered by the French astronomer Pierre Méchain, then later verified by his colleague Charles Messier on June 14, 1779.[6] The galaxy became listed as object 63 in the Messier Catalogue. In the mid-19th century, Anglo-Irish astronomer Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.[8]
The shape or morphology of this galaxy has a classification of SAbc,[5] indicating a spiral form with no central bar feature (SA) and moderate to loosely wound arms (bc). There is a general lack of large-scale continuous spiral structure in visible light, so it is considered a flocculent galaxy. However, when observed in the near infrared, a symmetric, two-arm structure is seen. Each arm wraps 150° around the galaxy and extends out to 13,000 light-years (4,000 parsecs) from the nucleus.[9]
M63 is a weakly active galaxy with a LINER nucleus – short for 'low-ionization nuclear emission-line region'. This displays as an unresolved source at the galactic nucleus that is cloaked in a diffuse emission. The latter is extended along a position angle of 110° relative to the north celestial pole, and both soft X-rays and hydrogen (H-alpha) emission can be observed coming from along nearly the same direction.[10] The existence of a super massive black hole (SMBH) at the nucleus is uncertain; if it does exist, then the mass is estimated as (8.5±1.9)×108 M☉,[11] or around 850 million times the mass of the Sun.

A new imaging project has been published on Cosgrove's Cosmos!
Messier 106 - is a huge energetic galaxy with a supermassive black hole at its core. It is located 22-25 million light-years away in the constellation of Canes Venatici.
This is a wide-field view that shows not only Messier 106 but also a score of small little galaxies scattered across the image field!
This image is the result of 5.6 hours of LRGB integration with my Askar FRA400 Astropgraph using a ZWO ASI1600MM-Pro camera and an IOptron CEM26 mount.
During galaxy season I always have trouble selecting targets for this widefield scope. Galaxies are typically small and require a longer focal length than this scope has.
I finally settled on the region around M106, as it is filled with a group of small galaxies, and I thought the entire field might be interesting to image.
This was shot over 3 evenings on the nights of 5-29-22, 5-30-22, and 5-31-22.
I was pretty pleased with the color and detail I was able to get with such a small scope. It makes me want to go back next year and capture this with my Astro-Physics 130mm APO and its ASI2600MM-pro camera!

Using the U.S. National Science Foundation National Radio Astronomy Observatory’s (NSF NRAO) U.S. National Science Foundation Very Large Array (NSF VLA), astronomers have revealed for the first time the huge flow of gas near a massive star in the making which allows its rapid growth. By observing the young star HW2 in Cepheus A, located 2300 light years from Earth, researchers have resolved the structure and dynamics of an accretion disk feeding material to this massive star. This finding sheds light on a central question in astrophysics: how do massive stars, which often end their lives as supernovae, accumulate their immense mass?
NASA’s Solar Dynamics Observatory captured this image of Earth and the moon transiting the sun together on Sept. 13, 2015. The edge of Earth, visible near the top of the frame, appears fuzzy because Earth’s atmosphere blocks different amounts of light at different altitudes. On the left, the moon’s edge is perfectly crisp, because it has no atmosphere. This image was taken in extreme ultraviolet wavelengths of 171 angstroms. Though this light is invisible to our eyes, it is typically colorized in gold.

Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 Angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.
