Following up from my re-worked image of M51 in #Siril using the #SyQon #Parallax script, I've reworked my 2023 🔭 image of C11 #thebubblenebula A few issues with the stars, but think its sharpened the detail around the central bubble.

Let me know your thoughts?

Some interesting facts! ...
Astrophotography of the Bubble Nebula (NGC 7635 / C11). A distinct, glowing, semi-translucent sphere resembling a cosmic soap bubble floats slightly below center. The delicate sphere features internal detail and a bright star illuminating its upper right edge. Surrounding the bubble is a vast cloud of glowing crimson and deep red emission nebulosity with fine, wispy filaments running diagonally across a dark space background sprinkled with tiny background stars. In the top-left corner, the text "PARAMOUNT OBSERVATORY" is written in a clean white font alongside a small telescope icon.

Pretty much a nebula focused night for the s50. Here is #ngc7635 #thebubblenebula. #seestar #s50 #space #astronomy #amateur
NGC 7635 The Bubble Nebula - telescope processed image. The delicate sphere is inflated by a fierce wind of particles driving outward at 4 million mph from an O-type star 45 times more massive than our Sun. NGC 7635 The Bubble Nebula - unprocessed image. The central illuminating star sits far off to one side rather than in the middle, because the expanding bubble collides with dense gas on one side.

Another nebula from last night, #ngc7635 #thebubblenebula. #seestar #s50 #space #astronomy #amateur
NGC 7635 The Bubble Nebula - telescope processed image. A stellar wind bubble carved out of interstellar gas by the intense radiation from a massive, super-hot star that appears dramatically off-center in the nebula. NGC 7635 The Bubble Nebula - unprocessed image. The massive central star blasts a stellar wind at over 4 million miles per hour to create the bubble, a shell expanding at seven light-years wide!

Good Monday evening. Just enough time for a quick observation before conditions deteriorate. Headed back to #c11 / #ngc7635 #thebubblenebula. Today’s image used the in board Light Pollution filter. Loading up the image from last weekend that just had the Moon […]

C11 / NGC 7635 The Bubble Nebula - telescope processed image with LP filter. It is created by the fierce stellar wind from a massive O-type star (SAO 20575), which is 45 times more massive than our Sun. C11 / NGC 7635 The Bubble Nebula - telescope processed image without LP filter. The star isn't in the middle; it’s off-center because the bubble expands into gas of varying densities in the interstellar medium. C11 / NGC 7635 The Bubble Nebula - unprocessed image with LP filter. The bubble is roughly 7 light-years across, meaning it’s about 40 trillion miles wide—large enough to swallow many solar systems. C11 / NGC 7635 The Bubble Nebula - unprocessed image without LP filter. The gas shell is expanding at an incredible rate of approximately 4 million miles per hour (roughly 1,800 kilometers per second).

The only image from the s50 from last night - #c11 / #ngc7635 #thebubblenebula. Conditions outside seem to have deteriorated after I left thens50 outside for the night. I had just got a new filter holder / dew shield as well. Looks like it’s going to be more […]

C11 / NGC 7635 The Bubble Nebula - telescope processed image. The 7-light-year-wide "bubble" is blown by intense stellar winds from the massive star SAO 20575, which is 45 times more massive than our Sun. C11 / NGC 7635 The Bubble Nebula - unprocessed image. The central star is actually off-center; it appears in the upper left because it's moving through space while pushing against a dense region of cold gas.

Last image for the Odyssey Pro for this morning. Here is an observation of #ngc7635 #thebubblenebula. #unistellar #odysseypro #space #astronomy #amateur
NGC 7635 The Bubble Nebula - telescope processed image. A 7 light-year wide gas sphere in Cassiopeia formed by the powerful stellar wind from an extremely hot, massive young star. It's an emission nebula glowing with ionized hydrogen. NGC 7635 The Bubble Nebula - unprocessed image. The bubble is blown by the fierce stellar wind of the central star, which is 45 times more massive and a million times brighter than our Sun.

Last of the 3-hour observations, here is #ngc7635 #thebubblenebula. #seestar #s50 #space #astronomy #amateur
NGC 7635 The Bubble Nebula - telescope processed image. A glowing emission nebula in Cassiopeia. Its 7-light-year bubble is sculpted by the extreme stellar wind from a super-hot, massive central star, BD+60°2522. NGC 7635 The Bubble Nebula - unprocessed image. The bubble's central star, 45x the Sun's mass, generates a 4 million mph stellar wind that carves the 7 light-year bubble like a cosmic snowplow!
