Comet C/2017 T2 Meets 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.

Catalina with Galaxy M101
Comet Catalina is flying away and it will be dim in the near future. There is limited time to watch the comet. At January 17th 2016, Catalina pass by M101, I use itelescope T14 at Mayhill, New Mexico, USA, take several images on line and composed them. The two objects seem to have the same size, however, they are far away.
