ISS with Crew Dragon Resilience transits Jupiter

ISS with Crew Dragon Resilience transits Jupiter by Tom Glenn, on Flickr

This composite image shows 39 consecutive frames that were captured during a transit of the International Space Station (with docked Crew Dragon "Resilience") across Jupiter. The event was captured from north of Lake Elsinore, CA, at GPS coordinates 33.732051N, -117.393964W, on November 19, 2020, 17:35:30 PST. The transit occurred when the ISS was at 27.6 degrees elevation, and at a range of 821km line of sight. This is not ideal, and Jupiter is also nearing solar conjunction. Nevertheless, this presented a unique opportunity to capture a planetary ISS transit. In addition to transiting Jupiter, the ISS passed close to Saturn and the Moon, which is shown in the video linked below.

I posted the following video on YouTube which documents the event, and shows the raw video footage, as well as maps and star charts used in planning:

The transit was recorded with a C9.25 Edge HD telescope, and ASI183mm camera with a 610nm far-red longpass filter. The exposures were 0.7ms each, and the frame rate was 57fps. The transit ground path was plotted in Google Earth using software written by Ed Morana (http://pictures.ed-morana.com/ISSTransi ... index.html). The transit sequence is composed of 39 consecutive frames containing the spacecraft. The composite image is created by using a maximum intensity blending mode ("Lighten" in Photoshop). Three of the Galilean moons, Io, Ganymede, and Europa are visible in the image. Note that the image is oriented with Jupiter's North Pole at the top. The GRS (Great Red Spot) is not visible......the subtle darker spot visible on the surface of Jupiter is part of the NEB (North Equatorial Belt). After the transit occurred, I manually tracked the ISS as it passed high overhead, which presented a more favorable view for recording details. The same equipment was used, this time with a 0.3ms exposure. The Crew Dragon Resilience can be seen docked on the ISS (link to still image below......this sequence is also contained in the YouTube video):

This is a remarkable image. Very well done!

Hey all,

Happy to present my recent images from November 2020. These are from our dual remote systems in Fort Davis, Texas consisting of:

Primary - Planewave 14" CDK/Paramount ME2/FLI PL16803 with Chroma filters
Secondary - Stellarvue 130/Paramount Mx+/ASI533MC (also on this setup is a SV70/SX 694 Trius; Askar ACL200/Canon 6d full spectrum).

First is the "Gumby" Nebula (which I always see instead of a running man), aka SH2-279 (14 hours LRGB):

---

Next, Messier 74 (13 hours LRGB):

---

And finally the Nautilus Galaxy, NGC 772 (10 hours LRGB):

---

I love the top image of nebula Sh2-279 and star cluster NGC 1981. The blue stars of NGC 1981 (top) seem to rise like fireflies out of the cerulean and magenta clouds of star formation region Sharpless 279!

I also love the delicate, beautiful shape and lovely colors of the "perfect" galaxy M74!

NGC 772 looks nice too! The teardrop shape, the mostly beige colors and that long blue "string" that runs across all the "beige-ness" - that's the one blue arm of NGC 772!

Wonders of Orion constellation



This time I tried to cumulate everything I like about Orion constellation in one picture. I used 2 imaging sessions to combine them into one pano picture. The main characters in the scene are: Flame Nebula (NGC 2024), Horsehead Nebula (IC 434), Running Man Nebula (NGC 1977) and Orion Nebula (M42), however there are plenty of other smaller deep sky objects, as well as loads of stellar dust.

EXIF: 20x 5 mins (right side), 20x 30s + 10x 5 mins (left side), Gain 120, Temp: -10C
Equipment: RedCat 52, ZWO ASI 294 MC Pro, ZWO Guiding Kit, AsiAir

Hi and welcome to Starship Asterisk*! That's a really nice view of the Horsehead region and the Orion Nebula!

My submission:

Heart Nebula, Soul Nebula, Double Cluster, and 2 Perseids meteors rising over a chapel on a hill in California.

Taken with a 135/2.8 lens and full frame camera, reference shot denoised and enhanced with a stack of 400 x 30s more stacked sky images.

This image is designed to give people a sense of just how large these nebulae are in the sky; each of the two red nebulae is over 4 full moons wide.

Heart and Soul by Dheera Venkatraman, on Flickr

That old chapel is certainly witnessing wonders of the sky: The Heart and Soul Nebula, the Double Cluster, and two Perseid meteors!

You are absolutely right that the Heart and Soul Nebulas are very impressively large in the sky. This is a magical image.

The Sun on November 29th, 16:58ut. Earlier today (Nov. 29th at 1311UT), Earth-orbiting satellites detected the biggest solar flare (M4.4) in more than 3 years.

I'm not that much into images of the Sun, but this picture looks fantastic!

The dark night skies of Idaho provide a stunning view of the Milky Way! Here is a panorama I captured to show the full sky look at the summer Milky Way from Craters of the Moon National Monument with a Nikon Z6 and 14-24mm lens. The photos were all 30 second untracked images. Ample green airglow was in the sky that night along with Comet NEOWISE hiding behind the clouds on the horizon. Can you spot a few well known deep sky objects like the Andromeda Galaxy and North American Nebula?

That's a really lovely image!

I would like to submit the following image for review for APOD.

The target in this image is the Cygnus Wall, the brightest part in the North America Nebula, NGC7000.

The data was shot on the night of September 19th, form my home in the Northern part of The Netherlands, Bortle class 5 skies.

Optics: TS-Optics 115mm Triplet APO
Camera: Astro modified Canon 750D
Subs: 43 x 600 seconds ISO 3200

Thank you for your time,

Kind regards,

That's a fine and impressive picture of the Cygnus Wall!

M51 Galaxy

Here is a portrait of M51 made in a collaborative team, cumulating nearly 100 hours of poses. This famous couple of interacting galaxies in the Big Dipper is often quoted to illustrate what galactic cannibalism can be.

To make the most of the participants' setups, we inlayed the roughs with the finest samples in those with the largest fields, which allowed us to benefit from the details in the galaxy as well as a sufficient field to highlight the very tenuous surrounding NFI, which is rarely seen in images.

We have selected from all the raw : 65 hours of Luminance, 15h of Halpha, 5h30 per RGB color layer

Acquisitions :
- Jean Baptiste Auroux (TSA 102 + Atik one 6.0)
- Julien Favre (TSA 120 + G2-4000)
- Mathieu Guinot (Esprit 120 + QSI 683)
- Fred Lamagat (RC8 @f/5 + Atik 4000)
- Matthieu Tequi (C9 Edge @f/7 + asi1600)

That is a truly lovely image of M51 and its companion galaxy, NGC 5195! Thank you!

Dust around Ngc 7497

That's a fine and striking image of a skyscape full of stars and streamers of dust, and an (apparently) single galaxy mixed into it all!

Sorry I just had to copy your image, because Starship Asterisk* didn't allow me to post your url.

Ann

thank you ;
generally i publish my images in my album and then if i want to publish for Apod i add my images in Apod submission, then i copy the bbcode to link the image here; i hope that this method is correct. After some controls i have seen that some zonal stretches have added a slight supersaturation of color in some areas for which i am adding now a more cleaned version :

Abell 370 Galaxy Cluster and The Dragon – 5 billion light years. KG Observatory, Julian CA.

https://www.astrobin.com/352w9d/B/

Wow, George, It's so impressive that you managed to show us "The Dragon", the set of lensed galaxies, from a distance of 5 billion light years!

Oh, no, wait! It's more impressive than that! It's the foreground Abell 370 Galaxy Cluster that is 5 billion light years away, so the lensed galaxy is even farther back into the early epochs of the Universe!

That's stunningly well done, George!

Ann

Thank you so much Ann!

The Perseus Cluster of Galaxies. KG Observatory, Julian CA.

We had a very heavy rain on November 8th with 60 mph winds. This finally cleared into an unusually transparent and steady sky. FWHM on the 15-minute Luminance subs was between 1.4" and 2.1". Perfect conditions for shooting tiny distant galaxies. (-:

This is a very fine portrait of the fascinating Perseus Cluster of galaxies!

Ann

Thank you Ann!
