Penumbral Lunar Eclipse VS a StrawberryMoon

2020 June 6th, a penumbral lunar eclipse happened above Beijing, China. I take this image at about 1:45 and 3:05am local time. The left image is taken at 3:05 which close to the greatest point. It is obvious that there is a little dark at the down side of the moon. Compare to the left, the right side image was taken at the beginning of the lunar eclipse, which is a normal StrawberryMoon. The two pictures use the same shooting parameters.
My equipment:
Telescope: AP130 GTX with field flattener at 873mm, 2X lens, the focus is about 1746mm
Camera: Sony A7RII
