投稿编号：561
作者：万亚光（中国）
拍摄作品：Scorpion(LBN 788&LDN 1495)
作品描述：
LBN 788&793，LDN 1495是一片位于金牛座的暗云，实际上就在著名的M45七仙女星团旁边，但是很少有人注意到它。我偶然发现这个天体看起来像一只蝎子穿过天空，然后计划并拍摄了它。这张照片充分展示了金牛座各种形式的暗云气。
通过使用500mm的广域焦距。我感觉就像一只巨大的蝎子穿过夜空。在它的爪子和尾巴上，有一些Ha的信息，我不知道它是如何形成的，就像星系中的Ha。

评委Warren A Keller点评：
"Having processed this field of view myself, I was extremely impressed with how perfectly this interpretation was. The colors and detail are wonderful, and it’s not overstretched as so many processors are doing today, which doesn’t respect natural light and contrast of the image. Well done!"
评委Ron Brecher点评：
"This image shows wonderful detail and depth in a field that contains several different kinds of objects. It required careful processing to show everything well."

投稿编号：012
作者：Patrick WINKLER（奥地利）
拍摄作品：NGC 6559
作品简介：NGC 6559 is an interstellar cloud of gas and dust located at a distance of around 5,000 light years in the constellation Sagittarius. NGC 6559 has a comparatively small diameter of only a few light years and is located close to the Lagoon Nebula (Messier 8). Therefore it is often perceived as merely an "appendage" of the Lagoon Nebula, although it is no less interesting. It is home to emission, reflection and dark nebulae, which produce a very beautiful play of colors and make the region very varied.

作者：Jeffrey Horne Drew Evans（美国）
拍摄作品：Heart Nebula Widefield
作品简介：The Heart Nebula, widefield. This image contains so many interesting things...the birthplace of stars, the death of stars, and just about everything in between.
Taken over the course of 57 nights, this was a team effort between my dear friend @Drew Evans and myself. Drew acquired the Oiii data from his Bortle 2 home observatory (NAZ Observatory), and I gathered the Hydrogen and Sulfur data from my Bortle 8-9 in Nashville, TN. Processing was done by yours truly.
Processing this image was a real bear...with so much integration time and such a wild dynamic range, it was very difficult to get the bright and faint parts to both look presentable. It took a couple of weeks, but I'm happy with this one.
We hope you enjoy this image as much as we enjoyed acquiring and processing it!

作品名字：The 2024 Total Solar Eclipse
作品简介：To capture this image, my family and I completely changed travel plans 2 days before the eclipse from East Texas to North East Arkansas. Arkansas ended up being one of the best spots for clear skies, so I'm thankful we switched plans. We carried over 400 lbs of equipment out to a field beside a small community church to shoot, including 3 tracking mounts, 5 cameras, 5 lenses, 5 tripods and a whole slew of other accessories (filters, intervalometers, etc). I set up all the equipment and configured all the imaging sequences with a countdown to start shooting immediately at totality. I was so caught up in witnessing totality that I forgot to remove the filters until 3 minutes into the 4 minute totality. It was an absolutely stunning experience visually and photographically and I came away with over 700 images of totality spread across the camera systems. Processing the images has been over a year in the making. With the help of some extremely intelligent individuals (all of which I can now call my friends), Francois Ayello, Colin Legg, Deepanshu Aurora, David Ackerman, and Ludo, we were able to write our own processing codes to process the images (image registration by phase correlation, linear HDR blending, image stretching, and adaptive structural enhancement). The results of this eclipse adventure are nothing short of a dream come true and I'm incredibly grateful for the friends who helped me along the way and for the opportunity to witness and capture such a monumental event.
拍摄器材：Nikon 300mm f/2.8 + Nikon D850 (1ev x 5) + Celestron AVX、Nikon 800mm f/5.6 + Nikon D850 (2ev x 5) + iOptron CEM70
拍摄参数：5 exposure bracketed sequence for each camera at the exposure spacing above using a plug in intervalometer.
处理软件：
PixInsight (calibration, debayer, stacking)
MATLAB (using my own written scripts/software to register, linear HDR blend, stretch, and enhance)
Photoshop (final touches and color enhancements)
拍摄时间：2024/08/04
拍摄地点：Corning, Arkansas, USA
评委Warren A. Keller点评：
“Simply one of the finest eclipse photos I’ve ever seen! The details of the corona are incredible, and the moon is also tastefully processed!”
评委Ron点评：
“This is one of the finest photos I have seen of the total solar eclipse of 2024. The photo looks very dynamic and even reveals the stars during totality. The turbulent detail in the corona makes it look dynamic and three-dimensional.”

作者：LELU Thomas（法国）
拍摄作品：Solar protuberance
作品简介：Using Firecapture software, I took 3,000 images with 2ms exposure time at around 80 frames per second on this portion of our star, showing this magnificent protuberance the size of several times planet Earth.
I then selected the best 1% of images using Autostakkert software, and performed histogram enhancement using ImPGG.
I perform two rises to obtain two images. One image with the protuberances but the sun's surface overexposed. And the other image, the surface of the sun without seeing the protuberances. These two images are then added to Photoshop with a “darken” blend mode, so that the two images can be superimposed and colorized. Then a few tweaks to the diagram and sky background to achieve this result.
拍摄器材：Sky-Watcher Evostar 72ED with coma correcteur and QUARK Chromosphere model (ERF filter 1.25’’). ZWO ASI174MM for camera imaginng with tilt ring (to suppress Newton ring phenomena).
All equipement on the Paramount MyT mount.
拍摄时间：2024/09/01
评委Tommaso Stella点评：
"Very nice dynamic contrast between the prominences and the solar disk. The sensation of brightness and warmth make the image very suggestive.Congratulations"
评委Christoph Lichtblau点评：
"Awesome view on this active area of the sun with very nice and soft processing and colors."
