What is the question or point of this post? It is like the title of a clickbait YouTube video.

No problem! I'm happy to answer any other questions too.
Astrophotography is quite a technical hobby but it's really rewarding IMO. I'd recommend giving it a try if you have the time and resources.

No, they would have less noise. A longer exposure means that more light hits the sensor, so you get more signal for the same amount of noise. In this case, assuming that the ISO (sensitivity) of the camera remained constant, doubling the exposure time would double the brightness (signal) while having the same noise level. In turn, the pre-stacked images would have a higher signal to noise ratio.

I remember those, they're amazing.
I only have the first 3 saved down. Anyone got the whole set?

so if op had chosen to do 2 second exposures instead, the pre-stacked photos would have more noise right?

Not as impressive as those hexagon patches that can be arranged and combined to resemble the real space station

This is poor quality at best, and a straight copy of another picture.

I’m surprised that Florida hasn’t tried to outlaw astronomy yet.

I just learned a bit about telescopes, like the fact that there are more than one kind.
