WilliamAstro Posted May 9, 2020 Share Posted May 9, 2020 What is the recommended exposure and gain to image the ISS? I use SharpCap by the way and does using ADC and 3x Barlow help? Link to comment Share on other sites More sharing options...
cletrac1922 Posted May 9, 2020 Share Posted May 9, 2020 William First of all welcome from Land Down Under Be very hard to image the ISS Download the APP ISS Detector, and you can set up the APP to notify you when the ISS is flying overhead What you are seeing, is the sun reflecting off the solar panels of the ISS We observe it all the time, and where I am, depending on the reflection, can be part of the sky above us, and then vanishes Where I am, when passing above the ranges to the west of us, takes 2 - 3 minutes from horizon to horizon It looks likes the lights on a high altitude plane you see at night time flying over, except the ISS is travelling lot faster The ISS takes about 90 minutes to do an entire orbit of the earth Hope have been of assistance John Link to comment Share on other sites More sharing options...
michael8554 Posted May 9, 2020 Share Posted May 9, 2020 Are you hoping to image details of the ISS such as it's shape ? You will need a very long focal length, what have you got ? Or do you just want to have a "star trail" ? Michael Link to comment Share on other sites More sharing options...

michael8554 Posted May 10, 2020 Share Posted May 10, 2020 8 minutes ago, John said: He has already done it: He certainly has ! Looks like he doesn't need help from us. But I'd say as fast an exposure as gives a reasonably bright image. 3X Barlow will either improve or ruin your resolution, you'd have to try.

Wyvernp Posted May 11, 2020 Share Posted May 11, 2020 Another good resource is https://transit-finder.com/ as it will show you when the ISS will transit the moon and the sun. This way you can be sure that you're pointing at the exact point where it will be so you can set up and point to the right location and tune your focus. I'm seeing a transit for me on the 28th so of course it will probably be cloudy.... but if not I'll stick the camera on my 8se and see what I can capture.
