Shooting stars with M10-R.
🕑 Added 2021-11-02 09:30:43 +0000 UTCI'm not very well equiped for taking photographs of stars, I use a single camera and a tripod and don't have any fancy star tracking gear. But every now and then I like to just point my camera up and make some exposures and see if I get anything interesting.
Looking online there's a basic formula to figure out maximum exposure time for shooting the night sky with a full frame camera, and that's 500/35 (35 being lens focal length, if it were 50mm it'd be 500/50 etc.). If using a crop sensor camera, I believe the formula changes to 300/focal length.
So, 500 divided by 35 equals 14.28 seconds. Meaning the maximum exposure would be 14 seconds. Anything beyond that would result with more prominent star trails due to the Earth spinning etc.
I've shared a bunch of examples here, the vast majority are the lens wide open (2.8) with a high ISO of 6400 and 12 second exposures (I had a choice between 12) The second photo was considerably longer, with an 8 minute exposure at 2.8 and 400 ISO... I was curious as to whether I could get noticable star trails.
I've tried this before with the Q2, but the Q2 has some tighter restrictions when doing long exposures and I fancied giving the M10-R a try last night. The lens I used is actually my slowest, I don't know why I didn't consider that when getting ready - I'd like to try again with the 1.4.
