California Nebula in SHO using 115 triplet with 0.79 reducer, and QHYCCD 268m. Just 3 hours of data. Could be the last image of the year for me.

A quick 'grab and go' of the Orion Nebula. A RGB image with only 15 minutes per channel. Captured with the RedCat51 and Anltia filters. #MoonHour™️Social #astronomy #Astrophotography #ThePhotoHour

The Orion Nebula. A stellar nursery roughly 1300 light-years away. Taken with the RedCat 51 / ZWO ASI533MC camera last night. Just shy of 3 hours of exposure time. #Northumberland #Astronomy

In my latest video on YouTube, I describe a new technique I've been using on my wide-field astrophotography images! While I am certain that I am not the only one doing this - I was so excited about the result that I stopped what I was doing to record a tutorial 🤓 Head over

The Horsehead Nebula! I used a technique known as LRGB imaging to capture this nebula in detail with my astronomy camera in the backyard. This iconic deep-sky object lies in Orion's Belt. It's an extremely popular winter subject - that never gets old even after years of

Monkey Head Nebula 📸 Last week, I set up a new budget-astro rig to capture one last nebula before galaxy season kicks in! The clouds held off long enough to collect 4 hours of total exposure time on NGC 2174 - an emission nebula on the border of Orion. While many people have

Gum 27 the Southern Tadpoles. Used some of the SETI Astro tools in PIX for the first time and am very impressed. I know it’s all the rage to remove the green in SHO images but I’ve always liked it. What does everyone else think? #astrophotography #nebula #southernskies #tasmania

A neat comparison of Mars, captured by Hubble (L) vs my backyard 24" scope just a few days later (R). It's staggering how far amateur ground-based imaging has progressed, even in the few years I've been in the hobby (granted when you have access to large aperture!)

3I/ATLAS is a mystery interstellar object noted for its hyperbolic path toward the Sun and very high speed relative to the Solar System. In mere days, #3IATLAS promises to yield new information, and perhaps, new questions. I appeared on NEWSMAX to discuss these developments.

My AI investment thesis is that every AI application startup is likely to be crushed by rapid expansion of the foundational model providers. App functionality will be added to the foundational models' offerings, because the big players aren't slow incumbents (it is wrong to
