davechris Posted March 25, 2023 Share Posted March 25, 2023 Hi Re shot below taken 24-03-2023 of the ISS travelling between the moon and Venus Sony A7iv Tamron 28 - 200. Set at 200 f/l 30 * shots on continuous mode. 1/8th sec @ f11. ISO 200 Stacked in Photoshop CC Obviously, the gaps between the streaks is the interval between exposures. However, why are the streaks jagged? Does anyone have any ideas? Thanks Link to comment Share on other sites More sharing options...
AstroNebulee Posted March 25, 2023 Share Posted March 25, 2023 Could it be vibrations from the shutter or any wobble. I'm sure someone with better knowledge will be along shortly. Lee Link to comment Share on other sites More sharing options...
fwm891 Posted March 25, 2023 Share Posted March 25, 2023 If your in AZ mode then the mount is driving in az/alt directions to track the sky and ISS is travelling in a different direction and the 'judder' is magnified 1 Link to comment Share on other sites More sharing options...
rickwayne Posted March 26, 2023 Share Posted March 26, 2023 A tumbling satellite can give a similar signature. But I think that if the ISS were tumbling, we'd have heard about it. Link to comment Share on other sites More sharing options...
