AstroJosh Thanks for joining my astrophotography page! I’ll be sharing new deep-sky images regularly, and many will be available for purchase Just message me.

I appreciate the support—clear skies and stay tuned! Astrophotography with Love and Purpose
How it all started…. Joshua Acosta’s story begins in Waukesha, Wisconsin, where a curious kid found himself constantly looking upward. The night sky wasn’t just a backdrop—it was a place of wonder, comfort, and endless possibility. When his mother placed his first telescope into his hands when he was 10, it

wasn’t merely a gift. It was an invitation. An opening to a universe he never stopped exploring. For years, Joshua lived his passion through the eyepiece, spending quiet nights as a visual observer, learning patience, awe, and humility in the glow of distant stars. But it wasn’t until his early forties—when astrophotography equipment became more accessible—that something inside him reignited. The camera became a new kind of telescope, one that could capture what his heart had always felt but his eyes could never fully hold. With it, astronomy transformed from a hobby into a calling. That calling grew even deeper after he experienced one of the hardest losses of his life. Joshua’s mother—a nurse who devoted over forty years to caring for others, and whose love for animals was as boundless as her compassion—passed away from complications after a stem cell transplant. Her absence left a void, but also a promise. In her memory, Joshua committed himself to something meaningful: that part of his astrophotography proceeds would go to no-kill animal shelters, honoring her lifelong dedication to kindness and care. Every image he creates becomes, in some way, a continuation of her spirit—an echo of the generosity and love she lived by every day. Today, when Joshua photographs the cosmos, he doesn’t just capture nebulae, galaxies, or starfields. He captures a connection. He captures legacy. He captures the feeling of that first telescope in his hands—the feeling his mother gave him, of love, of wonder, of hope, and always having a piece of someone who is no longer is with us....

The Elephant Trunk Nebula (IC 1396) 🐘✨

This is my latest reprocessed narrowband image of the iconic Elephant Trunk Nebula I took late last summer last year. I aimed for a balanced SHO palette that emphasizes the beautiful oxygen-rich blues while preserving the warm hydrogen and sulfur tones for a natural yet artistic presentation.

Captured from Wisconsin with:
🔭 Astro-Physics Stowaway 92mm refractor
📷 ZWO ASI2600MM Pro
🔍 Chroma 3nm SHO filters
⏱️ 12 hours total integration (4h Hα | 4h OIII | 4h SII)

This region, over 2,000 light-years away, is an active stellar nursery where dense pillars of gas and dust are slowly being sculpted by the intense radiation from nearby young stars.

Clear skies! 🌌

After several clear summer nights under the Wisconsin sky, here is my latest narrowband image of the Butterfly 🦋 Nebula,IC 1318, the beautiful emission nebula surrounding the bright star Sadr in the constellation Cygnus.

This region lies about 2,000 light-years from Earth and is a vast stellar nursery where new stars are forming within immense clouds of glowing hydrogen, sulfur, and oxygen. The dark lanes weaving through the nebula are dense clouds of dust that obscure the light behind them, creating the dramatic “butterfly” appearance.

Here is my latest astrophotography image another globular cluster - Captured the magnificent Messier 13 — also known as the Great Hercules Globular Cluster.

This ancient swarm contains hundreds of thousands of stars packed tightly together, located roughly 22,000 light-years away in the constellation Hercules. Every point of light in this image is a star, many older than our own Sun.

Typically these would look “bigger” “closer” in much longer focal length telescopes, but I really like capturing a larger area of the sky to appreciate it with my smaller refractor. I did provide a cropped version so you can appreciate the little galaxy NGC 6207 at the one a clock position. There is another hidden galaxy but it requires some zooming in and trained eye 🧐

Here is my lastest astrophotography photo I decided on M3 - Messier 3 — one of the oldest globular clusters in our galaxy, containing hundreds of thousands of stars packed into a sphere roughly 34,000 light-years away.

Here is a reprocess of The Triangulum Galaxy I took back late fall of last year. I focused on improving detail, color and stars. I am happy with result.

Here is my latest Astrophotography image. this is only 1hr in each R,G.B channels. Really awful viewed through your cellphone vs desktop view. I also have a closer cropped version.

The third image represents an added 2hrs in each channel for a total of 9. Makes the image pop, with longer integration time
