Comet C/2017 T2 and IC2574
My image shows the view when comet C/2017 T2 passes IC2574. The show of my image happens at about May 27th UT 6:00 a.m. 2020. I took my picture separately and composed them at last. I took the background stars (with IC2574) at the night of April 20 to 27, 2020 using a remote control telescop in China and the exposure time is about 16 hours (LRGB 4*4 hours). Then I took the comet image at the night of May 26 2020 and the exposure time is 15 min, using a remote control telescope in USA. Finally, I composed them in the one image.
