Though the photo was shoot in early summer, I can still remember the chilly wind outside. It was a mountain about 200 miles to the west of the city of Shanghai. Due the the latitude, the Milky way center is not as high in the sky as in Australia, so the unclean atmosphere affected the picture a lot. Thanks to the later process on computer, I get rid of most of them. But the noise is still there, I have to push the image, drag the curve to make it brilliant. It is not comparable to some masterpieces I saw online, the geographic condition is not good enough, the camera is lower level, the lens is so cheap($70) and poor quality, don't even talk about the equatorial mount which is no more than $80 in total and I need my eyes to guided the star, but after long times of guiding and several days of computer processing, everything became magic, I will love it forever.

An improvement from my previous attempt

Due to me feeling like crap and the sky being dominated by the moon, I thought I'd go over the frames I took last month with the 20D. Only had 12 frames (2 min and 3min)but DSS has produced a much better image than I was able to achieve before. I especially like the detail in the core of the Nebula (not blown out at all).

The Andromeda Galaxy or M31, is a spiral galaxy roughly 2.5 million light-years from our lonely planet. Along with the Milky Way Galaxy, M31 is part of the Local Group and contains approximately 1 trillion suns. When the light we see today from M31 left on its journey for Earth, there were no human beings on the Earth.

 

The smaller fuzzy dot above M31 is one of Andromeda’s satellite galaxies, known as Messier 110. The line just below Andromeda is likely an Iridium flare.

 

This is my first attempt using DeepSkyStacker to create an image. I used 29 light frames shot at 90mm and tracked for 60 seconds each.

The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611) is a young open cluster of stars in the constellation Serpens. Its name derives from its shape that is thought to resemble an eagle. It contains several active star-forming gas and dust regions, including the famous "Pillars of Creation", photographed by the Hubble Space Telescope.

總共30張以Photoshop手動疊圖而成(經過數次嘗試,無法使用DeepSkyStacker疊圖)

The image was produced using Photoshop by manually stacking 30 photos. (DeepSkyStacker somehow failed to stack the photos automatically after several tries)

This was my major target and effort for Calstar 2012. Taken over a series of 3 nights from September 13-16. My first evening under the stars had the camera rotated in the wrong position, so I couldn't use the subs very well. Because the camera position varied from evening to evening, this became an exercise in making a mosaic as well.

 

Because of the mosaic layout, amp glow from the camera was a big problem. My previous efforts to use DSS and PI to calibrate and stack were not able to sufficiently remove the glow. In the end, I loaded up Maxim, pointed it at darks that were in the temperature range of the lights and let it do a full calibration. The stacking of the resulting 59 fit files were done in DSS 3.3.3 beta 47 as a Sigma Clip. Processing was done in PI where I cropped, DBE, masked stretch, NR, and then a small MT to tighten up the stars. Brought the images into LR3 for touches to fix the blue halos in the bright stars (artifacts from calibration) and some final lines from the mosaic.

 

Final stack of 59 lights of 10 minutes at 400 ISO. Calibrated in Maxim with 63 darks, 27 flats, and 55 bias. Shot with the full-spectrum Pentax K10D camera with the cooler attached giving temps ranging from 19-21C. Telescope was a Stellarvue SV4 guided with Maxim using Orion SSAG on SV70ED. All used on a Losmandy G-11.

bottom-right ... RA: 04 08 52.468 Dec: +36 43 53.97

  

Lessons learned: Maxim does a good job with non-linear amp glow areas. I'll be going back to some of my problematic subs to recalibrate. I'll have to see what I can do to fix the blue rings in the bright stars as calibration doesn't seem to control these well.

This is M16 in Serpens also known as Eagle nebula. I collected the images on two evenings. However, I had to discard many frames due to windy and partially cloudy condition, which caused guiding problems.

I am proud that this image was selected as the Astro-image of the week (week 36/2017) in the German astronomy portal, astronomie.de.

For those who can read German, you can find a comprehensive description of M16 and discussion on my picture here www.astronomie.de/aktuelles-und-neuigkeiten/astrofoto-der...

NGC 7380 - Wizard Nebula (Reprocessed) by Paul Hutchinson

 

Wikipedia: NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. ...

Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer.

La nebulosa de Orión, también conocida como Messier 42, M42, o NGC 1976, es una nebulosa difusa situada al sur del Cinturón de Orión.6 Es una de las nebulosas más brillantes que existen, y puede ser observada a simple vista sobre el cielo nocturno. Está situada a 1.270±76 años luz de la Tierra,2 y posee un diámetro aproximado de 24 años luz. Algunos documentos se refieren a ella como la Gran Nebulosa de Orión, y los textos más antiguos la denominan Ensis, palabra latina que significa "espada", nombre que también recibe la estrella Eta Orionis, que desde la Tierra se observa muy próxima a la nebulosa.7

La nebulosa de Orión es uno de los objetos astronómicos más fotografiados, examinados, e investigados.8 De ella se ha obtenido información determinante acerca de la formación de estrellas y planetas a partir de nubes de polvo y gas en colisión. Los astrónomos han observado en sus entrañas discos protoplanetarios, enanas marrones, fuertes turbulencias en el movimiento de partículas de gas y efectos fotoionizantes cerca de estrellas muy masivas próximas a la nebulosa.
