Shooting over 4 nights (Centaurus was setting, so it could only be photographed in the first half of the night). The galaxy itself is bright, but the color had to be worked on a bit during processing.

The star field is simply breathtaking.

Askar FRA500 - a Petzval design, designed for full-frame sensors... Here we have a crop sensor - so the field is flat with plenty of margin... The other issue is that with guiding in Namibia at the beginning and end of the night, you have to fiddle with it - the temperature swing is too large - +30°C during the day and +5°C at night... And the stars get turbulent.

I also have a Samyang 500mm =) But I haven't shot with it yet. Even though I've owned it for almost a year. Wow, you really got far out there. Well, during the day it's +30°C, but by around 9 PM it's already below 10°C?

At 7, the sun sets... by 7:30, it's pitch dark... and it suddenly gets cold. By 9, it's already 15 degrees, and by early morning, around 3, it's down to 5... That's how it is...
I wasn't just passing by :) I went on purpose! There's no sky like this anywhere else!

Even in America? Well, some objects are visible for longer there, while others are simply visible.

You misunderstood me) Do you happen to have a blog so I can see how you ended up there and what it's like on the ground?

No, no blog for now :) I made a special trip during my vacation to see the southern sky when I had the chance to visit Namibia.

Well then at least write an article somewhere about how it all went from the idea to returning home)
