Excellent! The only thing I don't like about my Sony RX10 IV is that I can't get shots like that. I have tried and the small sensor generates just too much noise for the ISO required.

How do you manage to take such a long exposure and not have star movement. Heck I take a shot of 2 second and there are trails

Great work on this one, OneShot.

The length of the exposure is dependent on focal length of the lens. A wide angle lens (14mm) can have a longer exposure than a standard lens (50mm). There are a bunch of higher math formulas to figure out the arc second movement on you pixel size sensor. Someone came up with a simple math to figure out the maximum length of exposure. That is known as the 500 rule. Take your lens focal length and divide it into 500 and that is approximately the maximum length of exposure to avoid any perceptible star trails. Example: 14mm lens divided into 500 gives you 35.7. This means that the longest exposure you could use is 35 seconds with a 14mm lens. This is based on full frame sensor. You have to adjust for other sensor size. The smaller the sensor, the shorter the exposure. Sorry, I don't know what those adjustments would be. Happy shooting. PS. have a mug of hot chocolate with you on those cold night shots.

Thank you for the information. I was unaware of it. I never have done much if any nighttime sky photography. I will indeed give it a try now. Again thank you for your explanation.

Even with a 14mm lens, when I zoom in on the original, the stars are slightly smeared, not pinpoints. I try to stick with 25 seconds to minimize the trail. Thanks for looking!
