Explanation: This image of the Helix nebula (NGC 7293) is the outcome of the first collective project of Overall Photons, a collaboration totaling 342.5 hours of data from 19 amateurs astrophotographers. Imaging locations are multiple, mainly from Italy, Spain, Switzerland, USA, Brazil, Australia and Georgia (Europe). NGC 7293 is the nearest example of a planetary nebula, which is the eventual fate of a star, like our own Sun, as it approaches the end of its life. As it runs out of fuel, the star expels its outer envelope of gas outward to form a nebula like the Helix. The remaining core of the star is a small, hot, dense remnant known as a white dwarf. We were able to highlight also the weak external structure of ionized hydrogen thanks to the high signal collected.

Imaging scopes : ASA N12 / 12N, Askar 103APO, Askar 80PHQ, Celestron EdgeHD 8", Celestron EdgeHD 9.25", GSO 6" f/9 Ritchey-Chretien, Sharpstar SCA260, Sky-Watcher Esprit 150ED, Sky-Watcher Esprit 80ED, Sky-Watcher Evostar 72ED, Sky-Watcher Explorer 250PDS, Stellarvue SVX102T, Takahashi TOA-130NS, Tecnosky RC8 Carbon, TS-Optics 250mm/10" UNC f/4 Newtonian, TS-Optics PHOTON 200mm/8" f/4 Newtonian, Vixen ED103S

Cameras : Player One Artemis-C Pro, QHYCCD QHY268 M, ToupTek ATR3 CMOS 26000 KPA, ZWO ASI2600MM Pro, ZWO ASI294MC Pro, ZWO ASI294MM Pro, ZWO ASI533MC Pro, ZWO ASI533MM Pro, ZWO ASI6200MM

We can remove the OP logo if this is wished.

My recent capture of M33, the Triangulum Galaxy, has revealed some breathtaking details within this deep-space gem! At about 2.73 million light-years away, M33 is a spiral galaxy rich with HII and OIII regions—each telling a different story about the galaxy’s star-forming activity.

The HII regions I captured are glowing red patches scattered across the spiral arms. These are immense clouds of ionized hydrogen gas, energized by the intense radiation of young, massive stars. HII regions are the birthplace of stars, where dense clouds of gas and dust come together, igniting new stars that light up these stellar nurseries. M33 has some of the largest HII regions known, like NGC 604, which dwarfs many similar nebulae in our Milky Way!

Equally fascinating are the OIII regions, visible as bluish-green areas in the image. OIII, or doubly ionized oxygen, shines in a distinct hue thanks to even hotter and younger stars that produce intense ultraviolet light. This UV energy excites the oxygen atoms, creating a beautiful, unique color. These regions often mark some of the most energetic and recently active zones in M33, showing just how dynamic and alive this galaxy is.
Seeing both the HII and OIII regions side by side in M33 really shows just how layered and complex a galaxy can be. These are spots where new stars are being born and areas full of energy, all lighting up the galaxy’s spiral arms. Capturing this from my backyard reminds me of the sheer size and beauty of the universe—places where new stars and elements are forming, millions of light-years away. ima

Hi,

I would like to submit my mosaic image from the Antares/Ophiuchi region. My original 150 megapixel image is a mosaic of 3 x 3 elements, 40° x 27° in size. I took it in 5 nights last June at Rooisand Desert Farm, Namibia with a ZWO ASi183MC and a Voigtländer APO Lanthan 50mm @f2.8. I exposed for a total of 21 hours with an L-Enhance and 16.5 hours with a UV/IR filter.



The constellations of Scorpio and Ophiuchus offer so many magical colors. The bright Milky Way with its striking red hydrogen nebulae. The blue reflection nebula, as well as yellow and red emission nebulae around the star Antares. The blue Horsehead Nebula. The nameless, large red nebula on the left, and again and again veils of dark dust clouds. Of course there are also countless stars, but they only come out when you zoom in.
