The bright crater shown here is Aristarchus - the brightest feature on the Moon. Left of it is the crater Herodotus, with the channels of Vallis Schroteri stretching toward the top of the frame. In the upper right, Prinz is the crater that has half of its walls missing.

Taken around 2021-06-23 0535 UT, the waxing gibbous moon was 12.8 days past new and displaying 96.5% of its illuminated side. The Moon was at an altitude of 32°, and seeing was, at best, moderate this evening.

This is a stack of 55 of 300 frames shot with a ZWO ASI120MM through a Celestron Edge HD 925 with 2x Barlow. Stacking was done in AutoStakkert with processing in PixInsight and Photoshop.

Saturn is at opposition with Earth on 27th June (this is when Earth is aligned between the Sun and Saturn and so is at its closest to the planet). This means that at a mere 1.2 billion kilometers away Saturn appears bigger and brighter in the night sky and it's the best time to image it. This image was taken on 23rd June, very close to opposition so much more detail is showing including at least three of its rings as well as the Cassini division. Also visible is some of the banding in the planet's turbulent atmosphere caused by its fast rotation of 10 and a half hours. This image has been cropped to enlarge the features.

ISO-800 1/320, shot in raw but with the camera set on Mono. 250 images shot. Images pre-processed in Lightroom to remove the colour, and then exported at TIFFs. Best 75% of those images were stacking in Autostakkert! 2. The stacked image was duplicated; both processed using Lightroom and Photoshop CS2. One image was processed to bring out the prominences and the other to bring surface detail, then they were merged in Photoshop, Final tweaks made in Lightroom and Fast Stone Image Viewer.

This is the first time I've imaged the Sun for quite a while so I'm very out of practice!

The shadowed edge (terminator) of the first quarter moon as captured on June 30, 2017 using a Celestron C6 telescope with a ZWO ASI174MM camera.

This area also includes the locations of the Apollo 11 and 16 moon landings (see image notes). The craters Armstrong, Aldrin, and Collins are also visible in the large version of the image (named in honor of the Apollo 11 astronauts and located near to the landing site).

This month (July 2017) will mark the 48th anniversary of man's first step on the moon.

Seeing was average. The South Polar Ice-cap (composed of water ice & dry ice) shows up very nicely, but has shrunk since mid July. The dark patches includes (I think) Mare Sirenum to the SW, Mare Erythracum to the SE, & possibly Olympus Mons to the far NW, according to Sky & Telescope, Mars Profiler.

Mars is getting closer to Earth & will be in opposition at 2320 utc on October 13, 2020.

Almost out of nowhere I recently began to experience a halo on the limb side of my Mars images that I now understand is called the Mars Rind Effect. I had not heard this term until I started reading about the ghost rings that began appearing in my Mars images.

In the red channel image posted here, the rind effect appears as an outer ring and inner ring on the limb, or the left side of Mars' disk. The outer diffraction ring is dimmer than Mars but brighter than space. It is seen around the outside of Mars' disk as a halo that starts at about 12 O'clock and proceeds in a counterclockwise direction and starts to diminish at about 9 0'clock, and is gone by about the 8 O'clock position. As this outer ring begins to diminish in brightness, the inner ring that is dimmer than Mars and traces the inside of the limb begins to appear and it continues to about 6 O'clock on the disk.

The root cause of the effect is the stark intensity difference between the bright surface of the planet against the darkness of space with almost no gradient in between. This sharp and higly-contasted difference interacts with the aperture ring and the secondary mirror of the telescope to create diffraction rings in the image. In short, anything that sharpens the transition from the darkness of space to the brightness of the planet will cause the rind effect to be more noticeable.

An interesting charicteristic of the effect is that it is more noticeable in the IR channel, and less so progressing through the R and G channels to the B channel. It is barely noticeable in unsharpened images coming out of Autostakkert, but wavelet sharpening in Registax really makes it stand out.

There is no diffraction ring on the terminator side, or the right side of Mars. This is because the transition from daylight to darkness on the surface of Mars is a gradient over a larger number of pixels. In a somewhat like manner, it turns out that Jupiter and Saturn are less prone to diffraction rings because of the limb darkening effect that creates a gradient of light reflecting off of cloud tops instead of a distinct surface.

It turns out that I may have started experiencing the rind effect as a result of a comedy of successes as I have worked to improve my planetary imaging techniques lately. These successes are better focus and better collimation. Switching to Chroma filters may also have been an improvement that made the effect more noticeable, and better seeing that favored me on the night of this capture could have also contributed. That I am finally seeing this effect in my images may be a high-quality problem!

Now that I have identified the cause, the question becomes what to do about it. There are various Photoshop and WINJUPOS remedies that can be found in Cloudy Nights, I see images captured near the same time as mine that appear to have successfully removed the rind effect. Some imagers may deem these remedies to be "unfair" alterations of the "true" image, and personally elect to leave the effect in the image.

I have not yet made a personal decision on how to handle the rind effect in my Mars images. More to come!

Captured with a Nikon D5500 and a 10-inch Meade LX200 'Classic' f/6.3 wide-field telescope.

The above panel shows a partial set of images from the Total Lunar Eclipse of March 14, 2025 as seen from Washington DC. A complete set of images from start to finish could not be obtained due to clouds intermittently obscuring the moon throughout the imaging session.

Going anticlockwise starting from the upper left, the images shown above were taken at 06:02, 07:17, 07:29, 07:30 and 07:56 UTC. (Theoretically, the partial stage of the eclipse lasted from 05:09 to 08:47 UTC and the total stage from 06:26 to 07:31 UTC.)

I consider the orange-red image taken at 07:17 UTC to be a decent, albeit subjective, representation of the moon at about 19 minutes downstream from the theoretical maximum totality (at 06:58 UTC) of the eclipse.

NOTE: There is some residual color cast in the images which I am aware of but which I did not attempt to remove.

Equipment: Seestar S50.

I found the auto exposure option in Seestar to be unsatisfactory. Therefore, each image had to be manually exposed as best as I could judge based on ambient conditions.

Processing details: Except for the first 06:02 UTC image which was taken as a one-shot JPG all the others were recorded as about 15-second raw (i.e. AVI format) videos. These 170-180 frames-long raw videos were processed using AutoStakkert. Although Seestar is capable of internally stacking video frames it is technically more satisfying to use an external software, such as AutoStakkert, for that purpose because that option challenges the user to work toward producing a better result by experimenting with various quality-related options in AutoStakkert.

The quality of the stacked output image from AutoStakkert is determined by various factors some of which are the initial quality of and the number of the acquired raw video frames and the software's input parameters such as the alignment points size, the minimum brightness and the number of alignment points to be placed on the target lunar image in order to get an acceptable result.

The choice of Alignment Point Size and Minimum Brightness input parameters determines the number and positions of the Alignment Points placed on the target image by AutoStakkert. Care was taken to avoid having the alignment points fall outside the target image. This can happen because, obviously, AutoStakkert does not think for the user. Rather, one has to experiment with proper choices of values for the input parameters.

For the images (except for the first one at 06:02 UTC) shown in the panel, the data set below sets forth the Video Recordation Time in UTC / the Number of Raw (i.e. AVI) Video Frames Shot / the Alignment Point Size Input Parameter / the Minimum Brightness Input Parameter / the Outputted Number of Alignment Points. Each set applies to each of the four images shown in the panel.

07:17 / 173 / 168 / 25 / 68

07:29 / 171 / 168 / 20 / 63

07:30 / 182 / 152 / 20 / 72

07:56 / 177 / 96 / 25 / 42

The stacked images from AutoStakkert were imported into Lightroom for tonal, color and effects adjustments which being, by definition, subjective in nature means that photometric accuracy cannot be, and is not being, claimed. Lastly, the montage shown in the above panel was generated using Lightroom's Print Module.

It's been a long time since we did close-ups of the moon. Precise lunar tracking is much harder than using sidereal tracking so the results were not sharp enough. But now we've tweaked the Arduino code and the results are much better. This image is of Mare Nectaris (Latin for "Sea of Nectar"), a small lunar mare or sea (a volcanic lava plain noticeably darker than the rest of the Moon's surface). It is located just south of Mare Tranquillitatis.

Description

200/2500 frames

Jupiter with Ganymede in transit, 11th Oct 2021 (19:57 UT). Average seeing here tonight, a single AVI, best 4,000 frames of 12,000 frames (3 minutes) - Captured using FireCapture V2.5. Processed using Autostakkert V3.1.4 ,Registax V6 . Equipment used, Celestron C14 Edge HD, CGEPRO Mount, ZWO ASI224MC camera and Carl Zeiss 2X Barlow.

Here's a bit of the east limb of a 17.3 day old moon at 3:15 AM ET transit with 92.8% illumination.

Prominent in the lower left is the 133 km diameter crater Langrenus. Its stark shadow clearly shows a double central peak that rises 1,000 meters from the floor. The crater's walls soar steeply to 2,600 meters.

Dead center of the picture is 22 km crater Webb.

Just below and to the left of Webb is 10 km Webb H.

The small craterlet right below Webb H is Webb B at 6 km.

Our telescope, a Celestron 8SE on an Evolution mount can resolve a coin from 5 miles. At the lunar distance, the smallest feature it can resolve is 0.7 miles across, about 1.12 km, on a perfect night. I am sometimes asked if I can see Apollo visitation artifacts. Oh no, not even close. But we have a bunch of craterlets and neighborhood sized features generally detectable. If I shelled out for an 11 inch scope, resolution improves to 0.5 miles.

Kit: 8 inch f/10 SCT to a Nikon D7100 with 1.5x crop factor in live view HD movie mode. I used PIPP to choose the best 2,600 frames out of 5,600 and then asked Autostakkert! 2 to align and stack the best 260 of them into a 15% sharpened TIF image. Shake reduction sharpening in Photoshop was followed by a very light touch up in Lightroom.

As usual, Orlando-area seeing is the real limiting factor determining sharpness, but we try, we try.

The nearly full Earth must have been a gorgeous sight from the Moon. 8in Dob using a 550D camera. x31 1/6th sec exposures at ISO1600 processed in PIPP, Autostakkert & Faststone.

After a brief discussion of a subject of the "colorfull Moon" with Wyld-Katt I decided to try it myself. Definitely it works better with the full Moon, while in this phase the areas along the terminator become strickingly bluish...

Aquisition time (start of the session) : 05.09.2014, around 20:00:00 UT+4).

Image orientation: declination is horisontal and right ascension is vertical (in other words - scrambled :)

Equipment:

Canon 60D via Baader Planetarium MPCC Mk III on Celestron OMNI XLT 150 mm Newtonian riding Skywatcher NEQ-6 Pro SynScan mount.

Aperture 150 mm

Focal length 750 mm

Tv = 2 ms

Av = f/5

ISO 400

Gain NA

Software: Magic Lantern

Exposures: 53% of 300

Processing: contrast of RAW images was set to "Linear" and +0,5 EV was added in Canon DPP. Images was exported as RGB 8 bpc images, pre-aligned with StackReg plugin for ImageJ and processed in Autostakkert!2. Stacking result was subjected to Richardson-Lucy deconvolution in AstraImage 3.0 (Gaussian type PSF, size 0,9 units, 5 iterations).

The bizzare experiment was perfomed in Photoshop using Hue/Saturation and Saturation/Vibrance tools.
