The main reason stars were not seen from the Moon, or are not seen much from the ISS, is the exposure times are too short. Yes, you can easily see the
stars from Earth at night. I can look at my bright porch light, then look up to the stars and see quite a lot. With my digital camera I need at least
10 seconds to get some pin pricks of stars, 15 to 20 seconds preferably. Our eyes are remarkable devices. So on the moon, they never used long time
exposures, apart from the FUV camera, so even with a fast film it is unlikely they would have seen stars. I don't know why they wouldn't have tried
some time exposures from the shadow of the LM with their Hasselblads , too late now though.
You can not take a video of the stars with your video camera either, give it a try. There is a way to see them in real time though, using a night
vision device like the Binocular Photon Machine, or the Yukon Ranger. Not cheap, but I'd buy the BIPH if I had the money to spare. They see infrared,
which most cameras can not see, as they have an IR blocking coating on the lens.
Here are some stars. From the blurring of the lights on earth, this must be a few seconds of exposure. The cargo bay is not badly overexposed though,
which says a lot about the dynamic range of the camera, mostly Nikon F3s I think.

However, the puzzle to me is why there are no images of the Sun taken from the ISS, using a solar filter, one that would show sunspots. No need for
long exposures there. All the experiments from the ISS looking at the Sun use instruments that are not cameras. Lots of very clever scientific
instruments, but nothing from a regular camera with a filter. Can it be done? Why bother, I hear, when SOHO can take pictures of the Sun? Well, it
doesn't use regular cameras either, and I just want to see an image of the Sun looking anything like I can take with my old camera and some mylar
film or an old welding goggle lens. Surely it couldn't break the budget or interfere with their busy schedules too much? There are some mysteries and
inconsistencies with what NASA tells us, but light and human vision are very complex issues, so it's difficult to say exactly what is going on. Of
course the ISS is basically a military project, so we might never know the full story.
