NGC 1398 is an isolated barred spiral galaxy with an interesting double ring structure and feathery spiral arms positioned further out. It is located 65 million light years from the Earth, in the constellation of Fornax and has an estimated diameter of 135,000 light years, making it around 35 percent larger than the Milky Way. Over 100 billion stars are in the galaxy. Imaged in LRGB on our Officina Stellare RiDK 700 at El Sauce, Obstech, Chile Image Processing: Mike Selby System Control Software: Voyager by Leo Orazi

Image Description and Details :

Moon 1 day and 8 hours before the third quarter, September 9, 2020. All the majesty of the icon of the lunar surface structures - Ptolemaeus, Alphonsus and Arzachel (PAA). Faint shadows accentuate the relief of the craters. In Alphonsus Crater, a "web" of clefts with several dark halo craters (DHC) is an artifact of ancient lunar volcanism. The young Arzachel crater, the depth of the expressiveness of the terraced slopes and the impressive central hill, shows that it is the youngest of the three; above it a small Alpetragius with a dome in the center, on the left "budding" Thebit, further Rupes Recta (Straight Wall) and Rima Birt, on the right two large craters - Albategnius and Hipparchus. Two chains of craters - Catena Davy and Catena Abulfeda - are perfectly visible near Ptolemy.Achromatic refractor TS152/900, Barlow Celestron Ultima 2x (F eq. 2270mm), ASI290MM, Baader Halpha 35nm filter, EQ-ATM, FireCapture2,6, Autostakkert!3 (250/2000), Registax6.

WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. The bubble nebula is essentially visible in OIII. Image made in HOO mixing + RGB for the star colors.

The large and older planetary nebula, PK 080-10.1, was just discovered in the 90s of the last century by Motch, Werner and Pakull (hence the name MWP, which was formed from the initials of the discoverers' names. When they examined a weak X-ray source in the swan. The X-ray source turned out to be the central star of a planetary nebula. The central star is not a normal white dwarf, but a pulsating star of the type GW Vir. GW Vir stars pulsate with periods of less than one hour through non-radial gravity waves.
