I just tried to see the moving of this object. I made 20 frames with my Huawei P10 smartphone, with the monochrome camera. My star tracking is not so sharp, I have alt-az mount, I used only 10 sec expositions at ISO 1600. The shots was taken in every 10-12 minutes in this time intervall: 00:16-03:53am 2018. 08.16. Celestron Nexstar 8 SE, 25mm plössl eyepiece (magnification 80x). Of course I used a good adapter too. Frames has added with Gif maker pro mobile application.
