This series is actually just six shots. I uploaded one with stationary stars and one with star trails. Both use the same source images, 100 - 130 seconds of exposure each.

過了個年
又回到了清境
而妳和我的距離
仍是那麼的遙遠
因為武漢肺炎的疫情
延後開學
不小心多了一個朔
便與朋友私揪上山防疫
恰巧台14甲剛進行完路燈的工程
便再拍了一次星軌
利用幾乎是一樣的取景、曝光時間、數值、設備
來比較前後的改變
結果：
若是以肉眼來比較差異明顯
可以感受到天空變暗
但相機拍攝差異並不大
可能是因為進行了疊圖的關係

Taken from a meadow in front of Sentinel Peak.
Imaged with my old Pentax Kx and a 14 mm Rokinon lens. 240 sec total exposure with 31 darks at 12,800 iso
stacked/processed in sequator then further processing in gimp (color temperature changed to 5000K) then Image-J where it was de-speckled and a Gaussian blur of 2 pixels was applied
Seulement 5 clichés de 57'' (Canon 2000D+Astrodon+zoom 250mm+ monture SAM)+ flats et darks, prises en Dordogne, à l'ombre d'un chêne sous une lune à 95% ! Compilation Sequator, traitement Photoshop.... Bon, j'ai manqué de temps, les nuages arrivaient...
First attempt at a lunar photomosaic.
The main objective is to produce what looks like a full moon, but without the details of craters, maria, and mountains being washed out. Although ultimately I plan to use a better, future version of this in other pictures mainly for esthetic effect, I still want it to be reasonably accurate. The concept is simple: to juxtapose photos taken at different phases until a complete "moon" is created. in practice, however, it's quite tricky.
What makes it so tricky boils down to three main things:
(1) As the moon moves through its monthly cycle, its own apparent brightness varies wildly, so it's impossible use the same settings for every shot. This means the brightness/dimness of the image also varies.
(2) Because the moon's orbit is slightly eccentric, its apparent size varies slightly through the month. As sections are pasted into the final image, their size must be adjusted.
(3) Likewise, for the same reason, as viewed from Earth the moon does a slow "wobble", like someone very slowly shaking their head "no", so lunar features near the eastern and western edges of the visible disk may appear slightly broader or narrower at different times. In these cases the section being pasted might need to be laterally streched or squeezed.
The reason for the lengthy explanation is that I hope someone out there has some suggestions for dealing with these problems. I currently use Photoshop, and more rarely GIMP, but I'm open to other possibilities. I also use the Sequator star stacking program.
暴露在嚴重光害下
真的就拍不到銀河了嗎?
不過
正如同
我總有辦法
在茫茫人海中
第一個找到你
這次的天文祭第二晚
天氣勉強還行
雖然有些高雲來來去去
中間的空檔剛好可以來做測試
這次要測試的東西有2個
1個是新的鏡頭
Tamron SP 15-30mm F/2.8 Di VC USD
另一個是
STC的內置雙峰光害濾鏡
而剛好
這天農曆是22號左右
凌晨2.月亮已升起
再加上這邊往西南
南科和市區一帶光害很強
恰巧往南拍銀河測試
鏡頭的部分
15mm端 2.8全開
夠廣畫質也很好
邊角像差影響的範圍也算小
夠水準
雙峰濾鏡的部分
在城市做為光害濾鏡使用可行
只是顏色會怪怪的...
總而言之
這組合看來不錯
有機會可以上山多拍拍看
喔對
我先自幹
這組拍的時候曝光不足XD

Thanks to Sequator for stacking the sky and overlaying a separately stacked unmoving ground, and to StarTools for repairing lens aberrations towards the edges, I have pulled this image out of the "oh well" history and given it new life. The Third Quarter Moon had just risen, lighting up Mt. Cavell.

This stacked image was taken right after midnight on August 7, 2022 facing the southwestern sky from Ballinastoe car park near Lough Tay in Wicklow Mountains. This is Class 4 Bortle magnitude sky with light pollution from the surrounding towns and Dublin city so the contrast is rather poor.

Another attempt at imaging using the full focal length of the Celestron C8, though not very successful as it’s very soft, and doesn’t show any detail in the dust lane. That the galaxy is very low in the sky from this latitude doesn’t help. I’ve posted it anyway, for reference.
18 x 5-minute, ISO 3200, auto-guided exposures, taken with an astro-modified EOS 600D & Celestron C8 at f10.
The frames were stacked in Sequator software, and the result post-processed to increase contrast, reduce noise and adjust overall colour balance.

Last week, I spent seven amazing days in Šumava National Park, the darkest area in the Czech Republic. Two nights were clear, so I could enjoy even the beauties of the dark night sky.
Because of this rare opportunity, I borrowed better gear to capture the night sky. This image was taken with a modified camera Canon EOS 6D and Sigma 35 mm f1.4 lens. The sky is tracked, and stacked from three exposures and for the foreground, I used a focus stacking method (I took several exposures with different focuses).
I chose this composition already during the day. It immediately caught my interest. When I came back at night, clouds were floating across the Milky Way, but soon it got better and I could take what I wanted.
It was quite difficult to make the final image, but after about 4 hours, I got this result. It's new for me, so I hope you like this image, although you may not be used to it.
So proud of the opportunity to have this camera and lens, because the beauty, that hides behind this image, is caused mainly thanks to that. So thank you @gembecmartin for the loan.

four nights data spanning Nov & Dec put together with Sequator then stretched in GraXpert with a little polishing in LR.
My planned location to shoot the Milky Way was blocked off, so I was scrambling around at 3am in the dark but happened across this composition which is probably one of my favourite so far. Stacked 5 images for the sky, using Sequator which drastically reduced the light pollution, and 3 images for the foreground.
