IC 410 in H-S-S palette
Seen here is a populary imaged deep sky object: The Tadpole Nebula also known as IC 410. This is a faint and dusty emission nebula of more than 100 light-years across, located near the Flaming Star Nebula (IC 405) in a large star forming (HII) region about 12,000 light-years away from Earth in the northern constellation of Auriga.

​The cloud of glowing gas is sculpted by stellar winds and radiation from the embedded open star cluster catalogued as NGC 1893, which is just about 4 million years old. The massive, hot stars of this cluster are all very young, having only been recently formed from IC 410. The bright stars of this cluster are seen just below the prominent dark dust cloud near picture center. There are two gaseous streams in the centre of the image which is the “Tadpoles". These tadpoles, which consist of denser, cooler gas and dust, are approximately 10 light-years long and potentially sites of ongoing star formation.

This images consists of 9 hours of data from central london, a bortle 9 city. Data was processed with a HSS palette (where H-Alpha is mapped to Red, Sulfur II is mapped to Green and Blue channels) to give it a 'ghostly' (or ethereal) feel.

CTB-1 / Abell 85 -- aka the Medulla nebula, the Popped Balloon nebula, the Garlic nebula, etc.

This supernova remnant is extremely faint -- even with 72 hours of data captured over 14 nights. H-alpha and S2 dominate, but O3 is there, and bringing out its wispy tendrils from a sea of deep red without blowing out the rest of the image required some careful processing. The starfield is extremely dense, and maintaining the delicate filaments proved quite challenging. When it comes to processing this target, I learned after many iterations that less is more.

I love how delicate this object looks, especially considering it is the result of an exploding star 10,000 light years away.

Processed in the Hubble palette entirely in PixInsight.

Hope you enjoy!

Best regards,
Aaron W.

From Wikipedia:
"The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the east of IC 1396A. The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.

The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.

The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk Nebula. This pressure has triggered the current generation of protostars."

This is a mosaic which is processed from 12 500 single images. The final mosaic has 16 parts per 500 images. It was taken with an ZEISS achromat refractor and a Herschel wedge together with a ZWO ASI 294MC at the observatory and planetarium in Hradec Králové, Czech Republic. The goal was to create an 8k mosaic of the Sun. The planes are a planned bonus. I missed the first, but I got two later. I started the imaging session at 10:30 UT and ended at 11:30 UT.

Sunspots at dawn

Description: The sun this morning at dawn with many sunspots clearly visible thanks to the haze that acted as a natural filter. Especially the most visible spot, the one further down, is a very active region these days. Just today that sunspot has reached a size of about 2700 million square kilometers (900 MH). Consider that this is an incredibly large number, more than five times the surface of the Earth. Waking up at dawn can sometimes have positive aspects, such as observing this spectacle of nature.

NGC 300 is located in the inconspicuous constellation Sculptor and a prominent member of the "Sculptor group of galaxies".
Its diameter is 94,000 light-years, which is slightly smaller than our Milky Way. With a distance of 6 Mly, it is one of the closest galaxies to us in the southern sky and already easy to spot with binoculars.
