Mariner 9 - Olympus Mons Caldera - From Aster Cowart (terrasabaea.bsky.social) - https://flic.kr/p/22JUAxQ

Mariner 9 narrow angle camera of Olympus Mons' central caldera. This image was among the first images to confirm that Olympus Mons was a volcano - the largest known in the Solar System.

This image was taken on Mariner 9's 148th orbit around Mars, March 7, 1972.

Viking Orbiter 2 - Southern Hemisphere Monitoring - From Aster Cowart (terrasabaea.bsky.social) - https://flic.kr/p/25A3H5J

36 frame mosaic of Mars' southern hemisphere, taken on August 8, 1977 from an altitude of approximately 30,000 km. This image is in pseudo-true color, developed from a monochrome RED filter mosaic taken over the span of a few minutes by Viking Orbiter 2. A small patch of missing data along the horizon at upper right has been filled in for aesthetic purposes.

The mosaic is centered on Noachis Terra. North is to the left. The dark Terra Sabaea and light southern Arabia Terra are visible at top left. The Hellas Basin, shrouded in dust, is visible along the horizon at top right. Nearing its minimum summer extent is the southern ice cap at bottom right.

Saturn ring shadows and Enceladus - From Val Klavans (valklavans.bsky.social) - https://flic.kr/p/qBkXJE

This is an approximate true color view of Saturn. Shadows of Saturn’s rings are cast upon the planet (below the rings to the lower right). Saturn’s icy moon Enceladus also appears to the lower right of this image.

This composite is made of images that were taken by Cassini's camera system, the Imaging Science Subsystem (ISS) on March 7, 2015 and received on Earth March 9, 2015. The camera was pointing toward UNK (Saturn's moon Unk must have been behind Saturn at the time these images were taken), and the images were taken using the blue, methane band, and continuum band filters.

Titan Ring - From Val Klavans (valklavans.bsky.social) - https://flic.kr/p/mXdRJZ

This true color view of Titan was snapped by Cassini's camera system, the Imaging Science Subsystem (ISS) during its 101st flyby of Titan. Titan's south polar vortex is just barely visible to the lower right.

This composite is made of images that were taken on April 07, 2014 and received on Earth April 08, 2014. The camera was pointing toward TITAN at approximately 109,296 miles (175,895 kilometers) away, and the images were taken using the CL1, RED, VIO, BL1 and GRN filters.

Examining Andromeda - From Judy Schmidt (geckzilla.bsky.social) - https://flic.kr/p/bBaYrh

This came from the PHAT (The Panchromatic Hubble Andromeda Treasury) project. The image I started with was over 16000 pixels wide and was just a sea of noisey stars. Looking at it, you'd think you were looking at a section of our Milky Way because so many individual points of light are visible.

Usually, stars in other galaxies are more of a fine mist or cloud-like structure with only supernovas ever standing out as their own entities. Not so with Hubble's close up of Andromeda. And with two filters, 417W and 814W, I was able to produce a color image. Because 814 is infrared, I ended up selectively darkening the reddest areas to create visual interest and contrast. Otherwise, it would just be a sea of bright orange and blue specks.

Narrow-angle composite of Atlas taken on August 1, 2005. Atlas is seen near the left ring ansa here. Taken at a distance of about 877 000 km and at a low phase angle.

Frames taken through infrared, green and ultraviolet filters were processed to approximate natural color appearance.

Magnetic Journey - From Jason Major (jpmajor.bsky.social) - https://flic.kr/p/8dAfW1

A lineup of erupting magnetic activity on the sun's surface creates a trail of flares and coronal loops over 600,000 miles long. This is a portion of an image acquired today, June 26, 2010 by the Solar Dynamics Observatory's Atmospheric Imaging Assembly (AIA) 171, a sensor attuned to extreme ultraviolet radiation.

I rotated the image about 80º clockwise and cropped it as shown, and adjusted the image levels and sharpness to enhance details.

Wide field view around the Lagoon and the Trifid nebulae - From Ángel López-Sánchez - https://flic.kr/p/2jWtZmR

The Trifid Nebula (M20), with its pink (left) and blue (right) colours, is at the center. The Lagoon Nebula (M 8) is at its left. Very close to M20 is the open cluster M21, almost in the very center of the image. The faint nebula IC 4685 is also seen over M 8. The open cluster M23 is located at the bottom right corner (this cluster has a similar size to the full moon in the sky). The diffuse nebula IC 1283 is located at the top right, in the middle of a dark cloud.

CANON EOS 5D Mark III with a Tamrom 200mm lens, 15 x 5 minutes exposure at f/2.8 and ISO 800.

Piggyback using my old mount, battery powered but very well polar-aligned, no autoguiding.

Atlas - From Gordan Ugarković (ugordan.bsky.social) - https://flic.kr/p/n5x9y

$This neat, true color image of the moon Atlas emerging from behind Saturn's limb was taken by Cassini on June 7, 2005 at a distance of 656 000 km and a phase angle of 12 degrees. Atlas orbits just outside of the A ring. It's striking how Saturn's atmosphere bends the ring image (most visible at the Encke gap here) due to refraction. The planet's limb is pronouncedly blue because light passes through a greater column of cloud-free gasses when seen at an oblique angle like here. A subtle cloud band is visible on Saturn's disc. The rings visible here are the A ring, with a slice of the faint F ring at lower left. Image is a narrow-angle red/green/blue composite.$

NGC 6891 - From Judy Schmidt (geckzilla.bsky.social) - https://flic.kr/p/gK2QdM

Visually, NGC 6891 seems fairly simple. I can only see some very small knots of H-alpha. One of them is easy to spot. It's a very small, red dot near the left edge of the outer halo of material. I almost cleaned it up, thinking it was a cosmic ray.
