M 81/82

This is a collaboration between Thomas Engl and myself.

We collected the data for this project in 2015 and 2016.

I also made some RGB pictures, but was not able to "fill" the deep luminance with it while keeping a natural touch to the picture.

Now, a few years and projects later, I gave it another try.

Thomas Engl:
184*333 sec

Stefan Muckenhuber:
L: 219*300 sec
RGB: 6*1200 sec and 21*300 sec each

Total exposure time: 46,5 h

Telescopes used:
Skywatcher Esprit 100
TS triplet apo 102 mm f/7 with 0,79 Photoline reducer
6" f/3 Boren Simon

Processing in Pixinsight by Stefan Muckenhuber

Dear Stefan and Thomas

I think that it is a good second trial and a successful colaboration.

The picture has been dig a lot of tidal streams between this three Ursa Major galaxies.

Congratulation and best wishes
AstroEdy

Heart Nebula - IC 1805 by Joseph Nickerson, on Flickr

[Kinch]

Description by Sakib Rasool: (copied from internet)......
This nebula was first discovered by the astronomer Stewart Sharpless in 1959 who included it in his catalogue of HII regions under the name of Sh2-200. His catalogue was compiled after analysing photographic plates taken at the Palomar Observatory. The misidentification of HDW 2 (or Sh2-200) arose from the criteria of assembling the catalogue, which compared the separate red and blue photographic plates of the same region. If a nebula was more prominently visible on the red plate, it was deduced that it was more likely to be an ionized nebula. The other criteria was the presence of bright stars in the vicinity, which might be the source of ionization.
In 1983, Sh2-200 was included in the HDW catalogue of possible planetary nebulae by the astronomers Herbert Hartl, Johann Dengel and Ronald Weinberger. However it wasn't confirmed to be a true genuine planetary nebula until 2017 when spectra was taken as part of professional observations. In 1987, further narrowband observations by Herbert Hartl and Ronald Weinberger detected a large faint outer halo extending further than the central shell.

My name is Anthony Sleiman. This is my submission for APOD

Christmas Eve is almost here! and Santa is getting ready to go out! in these photos we can observe parts of the Milky Way, Jupiter, and the glowing light of the moon set!

These single exposures were taken in November 2020 in the Everglades National Park, with a sony a7r3 f4 15 seconds ISO 3200. Everything was caught on camera!

Thank you,

The Dolphin Head Nebula (Sharpless 308) is a composed of primarily ionized hydrogen that was been whipped into the miraculous shape of a dolphin head peaking out of the vast sea of space. This is truly a magnificent target and one of the most visually pleasing nebulae in the heavens. This image was processed in HOO due to the prevalence of OIII data and limited Ha data within its region. The nebula surrounds the Wolf-Rayet star in Canis Major and is less than ten degrees south of the brightest star in the sky, Sirius.
It is a difficult target to capture in North America due to it either remaining below or barely getting above 30 degrees, depending on your latitude. This image is a culmination of over 22 hours on integration time, captured in OII and Ha. This has been a lengthy time intensive target since I would only start acquisition when the target was above 30 degrees, and it only stayed above 30 degrees for a few hours a night. Also, all the data was collected with no moonlight with sky measuring 23.07 SQM per the observatory sky meter.
The image was captured in my private observatory in Uvalde Texas where we have beautifully dark skies. The Data was collected during the months of November and December 2020.
Equipment:
TEC 140FL telescope
Astro-Physics GTO1600e Mount
OAG w/Lodestar X2 guide camera
ZWO ASI1600mm pro image camera
Chroma OIII & Ha filters
Image Technical Data:
59 x 900sec OIII filter (bin 1x1 -10C)
30 x 900sec Ha filter (bin 1x1 -10C)
55 Darks
50 Flats
50 Dark-Flats

Thank you...

On the night of Geminids meteor shower peak an unknown object which appears to be a rocket entered the frame of my timelapse. This image is a composite of multiple frames that show the movement of the unidentified object from right to left along with a few Geminids meteors that fell into the FOV of the camera.

I suspect it's a rocket, however I am not sure which one it is. This image was shot from B.R. Hills in Karnataka, India at about 2AM on 14 December, 2020 facing in the South/South West direction. If anyone has any insight with regards to what that object is so let me know.

Dear All,

I am sharing an HDR composition of the total solar eclipse of 14th december, as observed from the shores of Limay river, in Patagonia. A Coronal Mass Ejection occurred around 14:45 (near our first contact) and was visible during totality as a dark bubble plowing through the corona. The red image shows SOHO's LASCO C2 image at the nearest time, rotated to approximately the same angle. Note how only natural eclipse observations allow to observ the lower parts of these phenomena.

Fantastic eclipse, very different from last year's, with a furious silver corona compared to the nacred one of 2019, a more symmetric corona, and prominences all around.

Cheers,

Guillermo Abramson

TITLE
California Nebula

DESCRIPTION
It extends in our skies for a length of more than five times the Moon and in these nights it "flies" silently over our heads: it is the California Nebula.
Although it is completely invisible to our eyes, the nebula begins to lower its veils with a simple camera, a telescope and a bit of patience.
With a handful of minutes of exposure, in fact, the California turns on: the beautiful red-magenta that characterizes the emission nebulae comes out quickly filling the image and our eyes.
Around her an endless field of stars that in a space of thousands of light years shines with shades ranging from sapphire blue to ruby red.
A bomb of pure energy 1000 light years away.

TECHNICAL DETAILS
Location: Piano Battaglia, Petralia, Sicilia
Camera: Canon EOS 60D non modificata
Camera Settings: ISO800, no filtri
Optics: TS APO 80/480, f6
Mount: Skywatcher HEQ5 guidata
12x360'' Light, 60x360'' Dark, Flat

Yes, I consent to the treatment of my image on your distribution channels.

The scale of things.
An airplane, 40 km away.
The Moon, 9375 times farther away than that at 375,000 km.
Jupiter, 22 million times farther at 88 x 10⁷ km.
Saturn, 40 million times farther at 16 x 10⁸ km.

Here's a composition of the total solar eclipse which crossed South America last monday. It shows the phenomes called "baily's beads". The clouds prevent me to make it symetrical, but thanksfully let me contemplate the whole event!

The planets Jupiter and Saturn are now close together.
Sure - only from if you are living on Earth.

The wether on the mountains looked fine and so i went to find a good site.
It was cold but a great feeling under 1000 stars.
