Image Description and Details : First "official" photo of our team Team Stellae Orientis Astrophotographie with the Perseus molecular cloud in LRGB by Yann SAINTY.

The Perseus molecular cloud contains the nebulae NGC1333 and IC348.

First lights on the fsq106 and the 2600MM and the result is up to my expectations. Combined with a bortle 4 sky this setup promises beautiful moments.

No moon so I wanted to image NGC1333 but seeing the beauty of IC348 next to it I could not resist the appeal of the mosaic despite the fact that it was not recommended during a first session with a new setup.

I imaged over 2 nights instead of 4 (lots of humidity and fog), which frustrates me in the sense that I only got half of the raws I wanted and so I had to shoot more processing. as desired, but you have to know how to have fun and try things!

Image Description and Details : NGC 7814 is sometimes called the Little Sombrero for its resemblance to the brighter more famous M104, the Sombrero Galaxy. Both Sombrero and Little Sombrero are spiral galaxies seen edge-on, and both have extensive halos and central bulges cut by a thin disk with thinner dust lanes in silhouette. In fact, NGC 7814 is some 40 million light-years away and an estimated 60,000 light-years across. That actually makes the Little Sombrero about the same physical size as its better known namesake, appearing smaller and fainter only because it is farther away. In this view, NGC 7814 is hosting a newly discovered supernova, cataloged as SN 2021rhu, the stellar explosion has been identified as a Type Ia supernova, useful toward calibrating the distance scale of the universe.

This exciting dark or reflection nebula can be found in the constellation Cepheus and is estimated to be about 110LY.

Polaris, the Northern Star, and cosmic dust.

(Captured the night of October 9-10, 2021)

Last Saturday night, from the "field of dreams" during Calstar, I tried to find something to photograph in the night sky that would feel a connection with the loss and grief we're experiencing since we said goodbye to Ariana, my soulmate for over 30 years, this past July.

Then, as I was staring at the night sky wiping my tears, I looked to the North... And there it was. What would be more meaningful for someone feeling so lost than the star that has guided the most people in the history of mankind? The star that, for now at least, tells most of us where North is.

There's an expression we use in Spain "No pierdas el norte". It literally means " Don't lose your north" but it's more like: don't drift, stay on course...

Meaning aside, Polaris is also a beautiful (triple) star to photograph. A yellow giant that shines in a bluish white color that also happens to be in the field of view (FOV) of tons of high galactic dust that, with enough exposure, we can get a glimpse of.

Polaris isn't an easy target for a deep capture either, maybe that's why it's not photographed very often (going deep I mean). First, because we can't guide. Guiding allows us to do very long exposures by "following" a star in our FOV, but when you point at the pole, stars don't "move" enough - if anything, they rotate, meaning some stars "move" up, others "move" down, etc. In other words, we can only take exposures as long as our mount and our precision when "polar aligning" (another process required to set up a deep-sky imaging rig) allow. Also, if we want to reveal the very faint high galactic dust surrounding the North Star, we need good skies and as much data (exposure) as we can get.

This image is 14.5 hours of total exposure. 7.25 hours of luminance and another 7.25 hours of RGB (one of my two scopes was capturing the L, the other scope captured the RGB), with all sub-exposures of 3 minutes each, all between 9:30pm and 5:30am that night. Therefore, the image is not outrageously deep, but the data was enough to allow me bringing out all that faint galactic dust somewhat tastefully (going deep isn't enough).

For Ariana, eternally.

The LOBSTER CLAW (SH2-157) & BUBBLE NEBULA (SH2-162), or Sharpless 157 (Sh2-157), is an emission nebula, around 12,000 light-years from Earth between the Cassiopeia and Cepheus constellations. There are several interesting features in this nebula rich region, including the Bubble Nebula, NGC 7635 (or Sh2-162), a HII region emission nebula which lies in a surrounding shell, and excited by the star SAO 20575. Also in the frame are the Wolf-Rayet massive star WR 157, two large open clusters of stars NGC 7510 and NGC 7654, and the nebula NGC 7538, which is home to the largest yet discovered protostar, 300 times the size of our solar system! This image was captured over the span of a week totaling 14.2 hours in narrowband. Each filter was mapped to the Hubble Palette.

This is the Fornax Dwarf Galaxy from an advanced request I did at telescope.live. I had to split it over 2 different nights to get it all due to issues with acquisition and while I didn't get all the luminance I intended it still turned out decent to me.

This complex is the eastern neighbor of IC1805 (Heart Nebula) and the two are often mentioned together as the "Heart and Soul". Located about 6,000 light-years from Earth, the Heart and Soul nebulae form a vast star-forming complex that makes up part of the Perseus spiral arm of our Milky Way galaxy. The Soul nebula is also known as the Embryo nebula, IC 1848 or W5.The Perseus arm lies further from the centre of the Milky Way than the arm that contains our sun. The Heart and Soul nebulae stretch out nearly 580 light-years across; the diameter of the Milky Way, is roughly 100,000 light-years across.Imaging telescope: Takahashi FSQ130EDImaging cameras: FLI ML16200Mounts: Takahashi EM 400 Temma 2MGuiding cameras: QHY CCD QHY 5 IIFocal Extender / Reducer: Tak QE 0.73x Software: PHD 2, Astro Pixel Processer, PixInsight , Sequence Generator Pro SGPFilters: Astrodon Ha + Astrodon OIII + Astrodon SIIAccessories: ATIK EFW3Original Resolution: 3500 x 2500 Dates: Sep 15 - Oct 5, 2021Frames:Astrodon Ha: 42 x 600"Astrodon OIII: 42 x 600"Astrodon SII: 42 x 600"Integration: 21 Hours.Center (RA, Dec): (43.568, 60.344)Center (RA, hms): 02h 54m 16.291sCenter (Dec, dms): +60° 20' 38.560"Size: 2.52 x 1.8 degRadius: 1.551 degPixel scale: 2.6 arcsec/pixelOrientation: Up is 180 degrees E of N

M45 - Pleiades: The Seven Sisters Star Cluster.

…lies about 444 light years away toward the constellation of the Bull (Taurus). A common legend with a modern twist is that one of the brighter stars faded since the cluster was named, leaving only six of the sister stars visible to the unaided eye. The actual number of Pleiades stars visible, however, may be more or less than seven, depending on the darkness of the surrounding sky and the clarity of the observer's eyesight.

Image Description and Details : A rocket launch was visible in Finland on night 27-28-9-2021 and I saw the first time it appeared on the sky from a sky camera. Then I suspected it could be visible again in about 90 minutes. I waited for it and was rewarded with a photo I am very satisfied with.
