NEW AR2723 Taken by Maximilian Teodorescu on September 30, 2018 @ Magurele, Romania
A new active region is visible on the Sun; after so many weeks of no spots at all, this double spot looks so great for all soar imagers, despite being a rather small group. Poor seeing for this session, but it was worth it to take the gear out in the field. Equip: 150mm achromat, Quark H alpha filter, ASI 174MM. Seeing 3/10.

55 NIGHTS WITH SATURN Image Credit & Copyright: Tunc Tezel (TWAN)
For 55 consecutive nights Mediterranean skies were at least partly clear this summer, from the 1st of July to the 24th of August 2018. An exposure from each night was incorporated in this composited telephoto and telescopic image to follow bright planet Saturn as it wandered through the generous evening skies. Through August, the outer planet's seasonal apparent retrograde motion slowed and drifted to the right, framed by a starry background. That brought it near the line-of-sight to the central Milky Way, and the beautiful Lagoon (M8) and Trifid (20) nebulae. Of course Saturn's largest moon Titan was also along for the ride. Swinging around the gas giant in a 16 day long orbit, Titan's resulting wave-like motion is easier to spot when the almost-too-bright Saturn is digitally edited from the scene.

THE LIGHT, THE DARK, AND THE DUSTY Image Credit & Copyright: Tasos Liampos
This colorful skyscape spans about two full moons across nebula rich starfields along the plane of our Milky Way Galaxy in the royal northern constellation Cepheus. Near the edge of the region's massive molecular cloud some 2,400 light-years away, bright reddish emission region Sharpless (Sh) 155 is below and right of center, also known as the Cave Nebula. About 10 light-years across the cosmic cave's bright walls of gas are ionized by ultraviolet light from the hot young stars around it. Dusty blue reflection nebulae, like vdB 155 at upper left, and dense obscuring clouds of dust also abound on the interstellar canvas. Astronomical explorations have revealed other dramatic signs of star formation, including the bright red fleck of Herbig-Haro (HH) 168. Near top center in the frame, the Herbig-Haro object emission is generated by energetic jets from a newborn star.

M33: TRIANGULUM GALAXY Image Credit & Copyright: Christoph Kaltseis, CEDIC
The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way. About 3 million light-years from the Milky Way, M33 is itself thought to be a satellite of the Andromeda Galaxy and astronomers in these two galaxies would likely have spectacular views of each other's grand spiral star systems. As for the view from planet Earth, this sharp image shows off M33's blue star clusters and pinkish star forming regions along the galaxy's loosely wound spiral arms. In fact, the cavernous NGC 604 is the brightest star forming region, seen here at about the 7 o'clock position from the galaxy center. Like M31, M33's population of well-measured variable stars have helped make this nearby spiral a cosmic yardstick for establishing the distance scale of the Universe.

" HARVEST MOON " ( LLAMADA ASÍ DESDE EL HEMISFERIO NORTE ) DESDE ROSARIO - ARGENTINA //// FOTO: ESMERALDA SOSA 25-09-2018 /// INFO: LICENCIADO EN FÍSICA JOSÉ LUIS LOMÁSCOLO

En el hemisferio norte se considera Harvest Moon ( Luna de la cosecha ) a la Luna llena que se produce en el período de tiempo comprendido entre dos semanas antes y dos semanas después del equinoccio de septiembre, por lo tanto, se produce generalmente en el mes de septiembre pero en ciertas ocasiones puede llegar a producirse en el mes de octubre.
Por lo general durante todo el año, la Luna sale en promedio unos 50 minutos más tarde que el día anterior, pero durante el equinoccio de otoño ( para el hemisferio norte ) el retraso de su salida entre un día y el siguiente alcanza un valor mínimo, por ejemplo, a unos 42° de latitud norte, en fechas cercanas a la Harvest Moon, el retraso de la salida de la Luna entre un día y el siguiente es de solo 23 minutos.
El nombre de Luna de cosecha se debe a que los agricultores podían extender la tarea de recolección de sus cosechas durante la noche al encontrarse iluminados un mayor tiempo por la Luna llena y sus fases cercanas.
En el hemisferio sur nuestra Harvest Moon no sería en el equinoccio de septiembre sino en el de marzo, esto considerando que retraso de salida de la Luna entre dos días consecutivos debe alcanzar un valor mínimo, para poner en evidencia esto consideremos la ciudad de Rosario - Argentina.
En el 2018 el equinoccio de septiembre se produjo el 22 de septiembre con una Luna llena el 24 de septiembre, el 23 la luna salió a las 17:46, el 24 a las 18:42 y el 25 a las 19:39, el 24 la Luna salió 56 minutos más tarde que el 23, el 25 salió 57 minutos más tarde que el 24.
El equinoccio de marzo se produjo el 20 de marzo, con una Luna llena el 31 de marzo, el 30 de marzo la Luna salió a las 18:52, el 31 a las 19:28 y el 1 de abril a las 20:03, el 31 la Luna salio 36 minutos más tarde que el 30, el 1 de abril salió 35 minutos más tarde que el 31 de marzo.

VENUS Taken by Shahrin Ahmad on September 25, 2018 @ Kuala Lumpur, Malaysia
Venus is now a whooping 41.6, more than double compared to Mars.
Its thinning very fast and getting lower towards the horizon everyday.

COMET 21P AND DEEP SKY OBJECTS Taken by michael jäger on September 17, 2018 @ Weißenkirchen Austria
Hello Nebulas NGC 2174 (below) and IC 443 (above) are popular deep sky objects for astrophotographers. On September 17, comet Giacobini Zinner stayed in the sky region. The image was taken with Leica Apo f-180 at aperture 4. The exposure time was 2 hours Regards Michael Jäger
