ISS transit of Mars
ImageISS transit of Mars, September 14, 2020 by Tom Glenn, on Flickr

This image was linked in my previous submission, but wasn't officially submitted itself. Based upon some feedback I've received, many seem to prefer this composite image, so I am submitting it here.

The International Space Station (ISS) transits Mars in this image. This is a composite image of individual frames extracted from a video of the event, and represents approximately 0.4s of elapsed time. Details on both the ISS and Mars are visible, despite the short exposure, including Syrtis Major on Mars. The orbital trajectory was calculated by Calsky.com, and the transit was only visible along a 90m wide corridor along the ground, leaving a margin of error of about 45m on each side of the centerline. The image was captured northeast of San Diego, CA, at exactly 05:15:47 local time (PDT) on September 14, 2020, and more information and data (including the raw exposure sequence) is available in the following video linked below:

Equipment used:

ASI183mm camera (no filter)
Focal length: 2350mm
Exposure: 0.35ms
Gain: 300 (66%)
ROI: 5496x1500 pixels

Mars occultation, images and time-lapse

Post by Thierry Legault » Sun Sep 20, 2020 9:18 pm

September 6, 2020: The Moon occults Mars. In Europe, one must go to the southwest of the Iberian Peninsula to observe the occultation before sunrise.

I prepare for the event as if it were a solar eclipse.
I take a flight to Lisbon with the C8 in my backpack and I decide to settle near Alcacer do Sal to take advantage of a grazing occultation: the lunar disc will "eat" the red planet while leaving its north pole visible.
Thus, Mars will reveal the rounded shape of the limb on the dark side of the Moon, as visible in the composite image:

And the time-lapse: https://youtu.be/XnF4N8Jbyhk


The processing of the 400 video sequences of 4s each and their registration on Mars required several tens of hours of work!

Great picture, Thierry. I'm very impressed at the enormous amount of work that went into producing it.

Starburst Galaxy IC10.
KG Observatory, Julian, CA

My second project with the new ZWO ASI6200M Pro – this time with 2x2 binning for smaller sub size (30 MB vs 120 MB) and higher SNR. The 2X loss of resolutions is not really noticeable. (-:

Camera gain was fixed at 100 with 60s Luminance subs and 300s RGB and Ha subs. Several hours of luminance subs were discarded in favor of the best FWHM.

Ha was applies over the LRGB with a starless screened overlay to help highlight the vigorous star-forming regions.

Fortunately the great positioning of IC10 allowed me to capture lots of subs – 9 hours per day from 8:30 PM to 5:30 AM over 3 days. Before that we had 8 days of high-altitude smoke from the CA fires. Skies were very dark, but just a handful of visible stars.

"Lurking behind dust and stars near the plane of our Milky Way Galaxy, IC 10 is a mere 2.3 million light-years distant.

Even though its light is dimmed by intervening dust, the irregular dwarf galaxy still shows off vigorous star-forming regions that shine with a telltale reddish glow.

IC 10 is the closest known starburst galaxy. Compared to other Local Group galaxies, IC 10 has a large population of newly formed stars that are massive and intrinsically very bright, including a luminous X-ray binary star system thought to contain a black hole.

Located within the boundaries of the northern constellation Cassiopeia, IC 10 is about 5,000 light-years across."

This is an extended cloud of gas and dust that is part of the low-mass star-forming region.
The two small galaxies are the spiral galaxy PGC 69472 (top - magnitude 15.5 and size: 2.1x1.6
arcmin) and the spiral galaxy PGC 166755 (bottom - magnitude 16 and size: 1.3x0.6 arcmin).
The bright yellow star in the center of the image is HR8625 (HD214710) (22h37m13.00s + 75 ° 22'18.0 ").

Thank you Ann! I just updated it with a new version that replaces Pixinsight's Photometric Color Calibration with a more traditional Color Calibration using the bright area of IC10 as a white balance. For this particular object, I believe this technique helps "cut through" the reddening effect caused by the Milky Way dust.

Hi there! It's been rather cloudy here lately, so I took it upon myself to go through some old Hubble data and see what I can do.

Attached you will find my processing of HLA data of the protostar IRAS 20324+4057. I incorporated Ha data from IPHAS as well, seen in the faint blue clouds of Ha in the background of the image

This object has been selected as an APOD before(https://apod.nasa.gov/apod/ap130904.html), but I feel this processing provides a unique view of the object, especially among the faint blue Ha clouds. In this image, 814W was mapped to orange, while 606W was mapped to Blue. Ha data was added as a cyan.

Moon on the Furnace

On the occasion of International Observe the Moon Night 2020, I send a sequence of full moon in penumbral eclipse over an old furnace.

The factory produced bricks that were exported to many Mediterranean countries: much of Tripoli (Libya) after the 1911 war was built with this bricks. As evidence of that productive past, only ruins remain: "o Pisciuottu", so the ancient establishment is called by the locals; and in the inexorable passing of time, silently and discreetly disintegrating, the Furnace awaits its destiny.
