Multiple takes on today's ISS solar transit: Canon R7 with Tamron 150-600mm lens (white images due to Bader solar filter) and Canon R6 on Nexstar 8 Edge HD (yellowish images due to the Thousand Oaks glass solar filter).

Today's transit of Tiangong with a Lunt 60 Hydrogen Alpha telescope and ASI1600M Pro camera (I added the orange color to roughly simulate what a hydrogen alpha image looks like to the eye). Pretty windy day induced a good amount of shake.

Got a good solar transit of the Tiangong space station today. The image on the left is with my Canon R7 and Sigma 100-400mm lens at 400mm. The one on the right is my Canon 80D and Tamron 150-600mm lens at 600mm. The R7 shows its stuff even with a shorter focal length lens.

The iconic image of the supermassive black hole at the center of Messier 87, has received its first official makeover, thanks to a new machine-learning technique known as PRIMO! noirlab.edu/public/news/noir… 🧵⬇️
The image of the M87 supermassive black hole originally published by the EHT collaboration in 2019 (left); and a new image generated by the PRIMO algorithm using the same data set (right).

Full moon and so bright 🌝! This #image shows the McMath-Pierce Solar Telescope at @KittPeakNatObs, a Program of @NOIRLabastro, just after sunset. Perfect time to see the Belt of Venus. noirlab.edu/public/images/io… 📸: KPNO/NOIRLab/NSF/AURA/P. Horálek (Institute of Physics in Opava)
