Starship Asterisk*

I've completed the 2023 first full cycle of the moon phases, in thermal wavelength (8-14um).
Here are the animations:

Andromeda https://flic.kr/p/2oegdWS

On the 10/08/2022 (10th Aug 2022) I took this picture of Andromeda in the Caingorms in Scotland which was at Bortle 2 skies. The moon phase was at 96% (Waxing Gibbous Phase).

I took this image using my setup, Canon 5D Mkiii (stock), Rokinon 135mm @ F2 and Star Adventurer 2i Star Tracker.

This was the second time I ever tried Astrophotography, and the first time using a star tracker and suitable lens.

Hi !

This image is an experiment I did using data from the GONG h-alpha network.

I wanted to show the development of some solar filaments that I also imaged myself in July last year and that showed a very nice development in the days they were visible.

I gathered data from the period from 4th of July until 16th of July with 2 day intervals from the GONG network and processed them in such way that I overlayed the images showing the filaments as they rotated with the sun during this period.

Clearly can be seen how the filament changed on the southern hemisphere and you can even see it as a prominence when it rotated away from Earth. On the northern hemisphere there was a large filament that ruptured during this period and lifted off, which can be seen as it suddenly dissappeared.

I like the result and it gives a nice idea of the activity of the sun in this period.

I made such a wide-angle shot of the sky, in which the comet is visible and the two iconic northern constellations are also on it. I photographed this comet in several focal points, but I liked this one the best.

Mars Approaches the Moon, January 30, 2023
Mars approaches the Moon, JAN-30-2023 by Tom Glenn, on Flickr

This image shows Mars and the Moon, approximately 14 minutes before Mars disappeared behind the lunar night side. I captured this image last night, through intermittent rain and clouds, from San Diego, CA. The image is a stack of 500 frames, captured in rapid succession at 20:20 local time (PST). Aside from the stacking, there is no compositing, no repositioning of elements within the frame, and no selective alterations to the exposure (global gamma and curves were applied).

The large crater along the terminator is Copernicus (diameter 96km, depth 3.8km). With Mars receding after opposition and currently subtending only 10" apparent size, Copernicus appears approximately 5x the diameter of Mars in this image. The large crater near the top of the image is Plato, which has a similar diameter to Copernicus, but is much older and has very different characteristics.

Hi there. Here it is ! The "naked" version of the dark nebula LDN 1622.

This is a starless version of the nebula which features faint details and beautiful dust and clouds all over. The monochrome rendering is naturally occurring due to the use of a H-α (hydrogen-alpha) narrowband filter at 656 nm (nanometers). I have always been very interested in "starless" renderings because they offer quite another appealing view.

"THE GREAT ORION NEBULA"
- Deepsky 750mm LSHO Stars: RGB
- Constellation Orionis



Another refreshing elaboration of the great Orion Nebula - and it's far from over ^^
Let the creativity run free, regarding the coloring, I call it "Fresh Banana Look", it somehow reminds me of an ice cream dessert in summer *g*
Narrowband filters for hAlpha, SII and OIII were used, the star colors come from RGB recordings. The colors were selectively adjusted by me, so we're pretty much in the "pretty pictures" range here But it's also fun every now and then

The Orion Nebula (M42 or NGC 1976) is an emission nebula in the constellation of Orion. Due to the high apparent brightness of its center above the 4th magnitude, the nebula is clearly visible to the naked eye as part of Orion's Sword south of the three stars of Orion's Belt. Overall, it has an angular extension of about one degree.
The Orion Nebula is a subregion of the interstellar molecular cloud OMC-1 in the Orion molecular cloud complex. It consists mainly of hydrogen. Stars form in the nebula, whose ionizing radiation makes the nebula shine in the visible range. It is therefore also classified as an H-II area. At a distance of about 1350 light-years, it is one of the most active star-forming regions in the galactic neighborhood, which is why it is a preferred study object for studying star formation. It is expected to evolve into a Pleiades-like open star cluster.
The main ionization source of the Orion Nebula is the star θ¹ Orionis C1, which is also one of the most luminous stars known with more than 200,000 times the luminosity of the Sun. However, the immediately adjacent and similarly configured De Mairan's Nebula has a different ionizing source and is therefore not part of the Orion Nebula.
