Arts and crafts for today

This is what a lunar eclipse looks like... from the surface of the Moon.

That dark circle is Earth.

Firefly Aerospace's Blue Ghost lander took this image last night.

My wife, granddaughter, and I were playing peek-a-boo with the Northern Colorado cloud cover last night, but I managed to get enough decent photos to make a collage of the Total Lunar Eclipse #lunareclipse

The Rosette Nebula - an emission nebula in Monoceros. Mosaic of two 30-minute integrations from the Celestron Origin; processed with DeepSkyStacker, Siril, and Photoshop

Collage of the Lunar-Planetary parade the past 9 days

The Moon is beginning its February Planet Parade. First Saturn, then Venus (and a very dim Neptune)

The Horsehead and Flame nebulas in Orion. The bright star is Alnitak, the left-most star in Orion's belt. (as seen from the Northern hemisphere). Mosaic of 2 images from Celestron Origin, 30 min total exposure at ISO 200 in each image. Mosaiced and brightness/contrast/sharpness tweaked in Photoshop.

The Moon occulted Mars last night - I assembled a video from about 18,000 images taken through a telescope: www.youtube.com/watch?v=_zL-...

Jupiter at opposition last night. Stack of the best 300 of 3000 images (100 each of red, green, blue). Moons left-to-right are Io, Europa, and Ganymede. 8-inch SCT telescope with 2.5x Powermate, ASI174MM mono camera with 200 gain and 10ms exposure. Sharpened and color-balanced to taste in Photoshop

More Polar Bears - video of a pair sparring.

Polar Bears! My wife and I took a trip to Churchill, Manitoba. The bears gather there every fall, waiting for the sea ice to form so they can go hunt seals. Sadly, the ice-free season is lengthening with climate change, endangering this population. More photos at photos.app.goo.gl/sdgpidnozybB...

Comet C/2023 A3 Tsuchinchan ATLAS on 21 October 2024. Mosaic of 5 stacked 13-image sequence, 10 second exposure at ISO 200 and F/2.2. Taken with a Celestron Origin.
