Space-time-Hf isotopic composition distribution of major continental magmatic belts in the Phanerozoic Eon. Compiled using global Hf and Nd data, and plate reconstruction models.

Solving #TCrB magnitude using raspberry pi zero and show the result on a LED display.

Moon and Venus over Carson Range Nevada. Vixen FL55SS @ 240mm, Nikon D7500.

The Pleiades (M45). Vixen FL55SS at 240 mm, Nikon D7500, 2min x 40, iso1600.

Comet Tsuchinshan-ATLAS shot using Vixen FL55SS @ 240 mm and Nikon D7500 @ iso64, 10s x 6. Processed in Pixinsight and Lightroom.

Comet C/2023A3 Tsuchinshan over southern Reno

Plate solving an image taken by Seestar 50 -> automatic star annotation and perform aperture photometry -> regression to get #TCrB magnitude.

I made a TikTok video on Tibetan Geology. This summer, we spent about two weeks in southern Tibet. This is one of my favorite geologic sites because you can literally touch a very important structure that helped to raise the Tibetan Plateau. Follow me @wenrongc on TikTok.
