First, my region is NOT good for seeing - this is a swamp. But in the winter we can get some very clear skies. I have been in the space business since 1978 (a long time) and am a member of Seesat (or also known as the Visual Satellite Observers) and have been tracking satellites for a few years. I use a DSLR (a Nikon D300s) and have been taking still images and resolving them at Astrometry.net of course. The thing that I am still working on is trying to get the very accurate time of the observations. I take ten second exposures and have photographed MANY satellites. If anyone has similar experience or suggestions about how to know exactly when the shutter opens and closes - can we talk?? I am a trial member so far and hope that people will reply and at least wish me good luck. Charles Houston, Texas |

| Are you manually taking the pictures? The best way I can think of is to note the time when you take the picture. I would use https://time.is/ for the most accurate timing. |

Quinn Groessl: After looking around a LOT, I have an app on my iPhone (cleverly called Time) that gives me very accurate time. Then I manually set it into my camera - that must introduce some errors. But there is not (that I have found) a good way to synch the camera to the computer. I need to know the time of the shutter opening and closing to within tenths of a second. |

I should have attached an example photo - here is a Russian upper stage dodging through the clouds. The satellite is the streak in the upper center of the photo. |

| I am interested in this also for some work applications. You would need a camera that can sync with a computer/smartphone or has a wifi sync function to set it's internal clock. And it would have to record start times to at least a tenth of a second. Or a remote trigger that can record an accurate time. There's no way I know to manually get 1/10th sec. Maybe, you could hold up a phone (showing the time to fractions of a second) behind your camera and record a video that captures the sound of the camera shutter, then review the video. I definitely wish you good luck! - Bert |
