It's amazing what's possible with backyard telescopes these days. I was able to capture a supernova happening in another galaxy in this photo... can you spot it? This photo of the pinwheel galaxy is formatted as a mobile wallpaper for you to enjoy, I'm posting these daily!

Yesterday I shared a photo of a supernova from a distance. This is what an older supernova looks like to my telescope after a couple thousand years. Behold the intricate beauty of the Crab nebula. This is formatted as a phone wallpaper for you to enjoy. I'm posting these daily!

Over 5 years ago I combined multiple astrophotography techniques to create a hyper-detailed moon photo. This photo changed my life thanks to the attention it received, and helped turn a hobby into a career. This is a mobile wallpaper format, Iā€™m still sharing these daily.

During the next full moon, a partial lunar eclipse will be visible depending on your location, like in this HDR photo captured from my backyard in 2022. This is formatted as a mobile wallpaper for you to save and use. Enjoy! Iā€™m still posting these daily.

Last year, the moon at Apogee passed in front of the Sun, causing an Annular Eclipse. I drove to Utah to capture a photo of the event, showing the ā€œring of fireā€ in all its glory. This is formatted as a mobile wallpaper, enjoy! Iā€™ll post another tomorrow.

The sun is putting on a nice show today. I've been shooting this flaring region nonstop for the past 4 hours, yielding some of the cleanest time-lapse footage I've shot to date. I'll share it soon. I formatted this as a mobile wallpaper, enjoy! I'll post another tomorrow.

Note- this is just a static image made from about 75,000 individual images. The timelapse I'll be sharing later will be a video from several hours of footage made from ~half a million photos.

I had to stop shooting thanks to a thunderstormā€¦ I got 5.5 hours of footage. Iā€™ll share it tomorrow morning so you can see how these features move. Turn on my post notifications if you donā€™t want to miss it!

Here's today's solar activity with Earth to scale. This image was created from over 5 hours worth of exposures using a modified telescope from my backyard. I'll share the time-lapse footage created from these images tomorrow morning.

Hereā€™s the time-lapse I promised you from yesterdayā€™s solar activity. Complete with Earth to scale and a bonus of the sunā€™s rotation. This is easily one of my cleanest time-lapses Iā€™ve managed over such a long period. Enjoy!

This week is a great time to look for earthshine after sunset, the dark side of the moon illuminated by Earth. In long exposures you can see lunar features, like in this composite photo I captured in 2019. This is cropped as a phone wallpaper for you, Iā€™m posting these daily!

Iā€™ve been getting tons of questions about how I capture the sun at this level of detail. I actually wrote an article about it you can check out: cosmicbackground.io/blogs/learn-abā€¦ Iā€™ll try and do a more comprehensive X post about it as well soon. I want more people to learn to do this!

By setting up a telescope in exactly the right point on Earth and using an extremely fast shutter speed, I can capture the ISS against a specific backdrop. In this case, the Apollo 11 landing site. This is cropped as a phone wallpaper for you. Enjoy! Iā€™ll post another tomorrow.

By using 2 cameras and 2 telescopes, I can create composite images of our moon that more accurately demonstrate the feeling of watching it drift through our skies. The moon is a perfect subject for art. This is formatted as a mobile wallpaper, enjoy! Still posting them daily.

Using a 12" scope I photographed this star-forming region of the Milky Way for dozens of hours. Stellar winds and gravity sculpt fascinating shapes from the interstellar medium, leaving behind these beautiful features. This is formatted as a mobile wallpaper, enjoy! More coming!

A shot of the moon and Venus captured from a camera I left in Texas (while operating from home) Tonight Iā€™ll point this camera at parts of the Milky Way to capture detailed panorama of our home galaxy.
