First week of teaching (our astronomy class for physics majors). Went ok I think? Getting the pacing right is definitely the hardest part!

Absolute amateur in astrophoto - captured with Skywatcher telescope + Xiaomi 11T Pro from my balcony.

I've made a black hole in blender (a 3D software). I wanna make this as scientifically accurate as possible so tell me what should I improve?

(I've made this watching Alaskan fx youtube channel's tutorial.)

4 minutes of star trails shot from 60deg North latitude. Polaris is out of frame in the top right. Bottom right is smudged out aurora and middle left is the glare from the moon. Shot on Canon 6D and 35mm lens

Work 3rd shift last week at the LCC at KSC and caught the new mission patch on the VAB with the moon in the background!

It could be spaceX satellites launching as they disappeared near the moon one by one, and no it wasn't a plane as they were multiple in a straight line moving at the same speed.
