"Stadius, with Eratosthenes and Copernicus"
Stadius is the 69 km wide crater hiding in plain sight, just below and right of the center of this image. Stadius is a ghost crater, a remnant of an ancient lunar impact crater that has been nearly obliterated by basaltic lava flows. Those floods covered all except for the very highest rims of Stadius crater, hiding it from view except for a faint, disconnected ring of hills. The interior of Stadius is pocked by many tiny craterlets. These are secondary craters caused by large chunks of material, blasted skyward by the impacts that created it's two neighbors, Eratosthenes (above and right) and Copernicus (left). These chunks slammed back onto the Moon, digging craters of their own.
Eratosthenes crater was the subject of my Earth Day post. It is 59 km wide and 3.6 km deep. It has a well-defined circular rim, a terraced inner wall, a triangular cluster of central peaks, an irregular floor, and an outer rampart of ejecta. Close examination shows a spray of craterlets, most visible here towards the north, across the Apennine Mountains into Mare Imbrium. Eratosthenes, at 3.2 billion years of age, appears quite young in comparison to Stadius crater. It does lack a system of rays, the hallmark of the youngest lunar.craters.
The youngster of this trio is, of course Copernicus. Copernicus dominates the terrain. It is a large crater, with a width of 96 km and a depth of 3.8 km. It is visible from Earth through binoculars. The circular rim has a discernible hexagonal form, with a terraced inner wall and a 30 km wide, sloping rampart that descends nearly a kilometer to the surrounding landscape. The crater floor has not been flooded by lava, so features of the interior can be seen in unaltered form. The terrain along the bottom is hilly in the southern half while the north is relatively smooth. The central peaks consist of three isolated mountainous rises climbing as high as 1.2 km above the floor. These peaks are separated from each other by valleys, and they form a rough line along an east–west axis.
Unlike Eratosthenes, Copernicus sits at the center of a vast system of rays. These are visible in this image as streaky patches if lighter-toned material, especially south of Eratosthenes and draping over Stadius. The rays spread as far as 800 kilometers across the face of the Moon. As they overlie even the ray systems of other young craters, such as Aristarchus and Kepler, it can be inferred that Copernicus formed more recently. The rays are less distinct than the long, linear rays extending from Tycho, instead forming a nebulous pattern with plumy markings. In multiple locations the rays lie at glancing angles, instead of forming a true radial dispersal.
An extensive pattern of smaller secondary craters can also be observed surrounding Copernicus. Many of the largest of these are seen in this image; a multitude of tinier craterlets lie below the resolution of my imaging system. Some of these secondary craters form sinuous chains in the ejecta. Note the snaky chain that runs between Copernicus and Eratosthenes, beginning to the west of Stadius and continuing out if the image at center top.

Dec 01 - Think this is the end of my Mars season. Too far and small to capture much detail now. It's been a good one though.
Just going to keep updating this throughout the apparition rather than keep putting new images up. Also marked out a few of the more interesting and well known features. I was delighted when I managed to find Olympus Mons although it seems to be brighter this year than in previous apparitions.
Seeing variations make a big difference to detail that can be seen as does my ability to process them. Seeing was much worse later on in the season as Mars receded and got smaller.

Taken from Oxfordshire, UK with a William Optics 70mm refractor, 2x Barlow and Canon 1100D on an EQ5 Pro mount on a permanent pier.
ISO-800 1/1000 sec exposure. 200 frames shot, cropped and centred using PIPP (the mount was tracking at sidereal rate rather than lunar rate so the Moon had wandered during the time I was imaging), then the output turned into an AVI. The best 75% of the frames were stacked with Autostakkert! 3 Beta, and processed in Lightroom, Focus Magic and Fast Stone Image Viewer.
This was about 16 hours before the Perigee Full Moon. With the weather forecast not being great for the night of Full Moon, this may be the closest I get!
This Moon image is dedicated to my lovely friend Richard Bailey who loves the Moon and is currently very poorly. Thinking of you Richard xxx
UPDATE: Richard sadly passed away not long after I'd posted this on 19th February. RIP my lovely astronomy friend :(

My First Mars!
This week, Mars is as close to Earth as it will be for another decade or so, and it it is at opposition, that place when it is directly in the opposite direction from the Sun as seen from Earth. This makes Mars relatively large and bright in the night sky, very easy to detect.
I have never actually photographed the face of Mars. Last night conditions were good, and I had the right equipment to try. This is the result. Photographing it was satisfying, but the experience of seeing it "live" was deeply moving. It makes the planet real, and you experience it as another world. This is especially meaningful, because it is a world we have populated with robotic vehicles of our own making, one we are actively exploring, and one we may likely set feet upon before the next time it is again as large and bright in our skies. As I type this, I am learning of other friends who were viewing Mars about the same time as I was; further, I know that a great many of the people who share this city with me are contributing to the collective human effort that is the exploration of Mars.
I will include in a separate upload a graphic that shows the features on Mars that were visible when I took my video.

The sky was hazy but yet better than it had become closer to noon.
To compensate the lack of dark frame I have substracted the modal grey value corresponded to the empty space part of the image. It had reduced grainess somehow, but I did it on stacked images which doesn't feel right. It didn't make a 100% substitute for a dark. Perhaps both approches would work together in concert by removing both camera's dark currents and the contribution of the light scattering in the air(?).

Right now, in summer, the seeing conditions here in Victoria are horrible. I won't bother to try shooting the moon again until the fall when we start to get cool clear nights. Went through some old stacks and found this one I had not shared because it had some colour fringing I could not remove. I fixed it and am now happy to finally share it. I have already posted another shot from a different stack from this night, but it looks very different to this one. Hope I get more nights like this one was!
I don't know how many images I stacked here.... probably 10 or 12. (out of 35 shots in this sequence)

“Eratosthenes, Stadius and Copernicus"
May 11, 2022
Eratosthenes crater, on the right, is nestled against the Moon’s Montes Apenninus, or Apennine Mountain chain. It is 59 km wide and 3.6 km deep. It has a well-defined circular rim, a terraced inner wall, a triangular cluster of central peaks, an irregular floor, and an outer rampart of ejecta. Close examination shows a spray of craterlets, most visible here towards the north, across the Apennine Mountains into Mare Imbrium. It does lack a system of rays, the hallmark of the youngest lunar craters.
Eratosthenes, at 3.2 billion years of age, appears quite young in comparison to Stadius crater. Stadius is the 69 km wide crater hiding in plain sight, just below and right of the center of this image. Stadius is a ghost crater, a remnant of an ancient lunar impact crater that has been nearly obliterated by basaltic lava flows. Those floods covered all except for the very highest rims of Stadius crater, hiding it from view except for a faint, disconnected ring of hills. The interior of Stadius is pocked by many tiny craterlets. These are secondary craters caused by large chunks of material, blasted skyward by the impacts that created it's two neighbors, Eratosthenes (above and right) and Copernicus (left). These chunks slammed back onto the Moon, digging craters of their own.
The youngster of this trio is, of course Copernicus (merely 800 million years young). Copernicus dominates the terrain. It is a large crater, with a width of 96 km and a depth of 3.8 km. It is visible from Earth through binoculars. The circular rim has a discernible hexagonal form, with a terraced inner wall and a 30 km wide, sloping rampart that descends nearly a kilometer to the surrounding landscape. The crater floor has not been flooded by lava, so features of the interior can be seen in unaltered form. The terrain along the floor is hilly in the southern half while the northern half is relatively smooth. The central peaks consist of three isolated mountainous rises climbing as high as 1.2 km above the floor. These peaks are separated from each other by valleys, and they form a rough line along an east–west axis.

A time-accurate color composite image created from the 8 consecutive 30-second video captures required to create this image, over the course of approximately ~4 minutes. A separate acquisition is required for R, G, B, and L for Saturn's brightness and R-G-B-L for the moon's brightness, as their apparent exposure requirements are very different. While it CAN be captured in 4 consecutive acquisitions, rather, the color is captured best with proper exposure for each.
Post-processed using Autostakkert!3, PixInsight, and combined in Photoshop. After stacking, combining, and processing was done, the moon and Saturn were then recombined into one final image.
The location of Saturn chosen was where it was in relation to the moon at the midpoint of the moon exposure acquisitions, for scientific accuracy. That is our duty, to remain ethical.
Using a monochrome camera, it takes time to capture all the color channels, so time elapses. As time elapses, in the apparent close quarters where two objects are moving independently in space, they must be treated separately and recombined in post, requiring a composite image.
We all hate composite images. But, when they are created with transparency and ethics, that’s what we as astrophotographers need to do. We must remain ethical and accurate at all times.
We can help each other learn how things are done, and how to do them properly.

Here is a view of the planet Venus captured during the day. Venus is currently only 13% illuminated and heading between the Sun and Earth causing the crescent to get progressively thinner and the planet to get progressively larger.
