The Inner Corona of the 2024 Total Solar Eclipse | 800mm I captured this image of the sun’s innermost atmosphere (corona) during the 2024 total solar eclipse using a normal DSLR camera and lens. This image is the culmination of hundreds of hours of research, learning, testing, and coding. I’m also proud to say that none of this image is AI generated and every exposure used for this image was taken by me during the solar eclipse. After witnessing the 2017 solar eclipse in the USA, I became absolutely obsessed with solar eclipses, particularly photographing them. This led me to dive head first into the elusive field of extreme HDR solar eclipse photography. I then spent the next year writing my own image processing software based on the pioneering numerical methods proposed by Miloslav Druckmuller in his research papers. I was blessed to meet and work with 5 extremely talented individuals who all shared the same goal as me in capturing extremely detailed HDR eclipse images. Without their partnership, friendship, and advice, I would not have pushed myself as far and definitely would not have succeeded in capturing these images (more details on them in my article). I’m so grateful to have been given the opportunity and resources to be able to witness and capture this solar eclipse and for all the folks who helped and encouraged me throughout the process. God’s creation is incredible and his perfect glory and intricate design is so readily apparent when we look up at the skies.

The Outer Corona of the 2024 Total Solar Eclipse | 300mm Here is the second image I captured during my 2024 total solar eclipse adventure. This image was captured at 300mm which nicely fits the outer corona and surrounding starfield usually hidden by the bright daytime sky. I was able to use the 800mm camera system to expose for the inner corona while this 300mm camera system exposed for the middle/outer corona. By resizing the 800mm images, I can blend them with the 300mm images and display all of the corona at the 300mm FOV without missing any details. This image is particularly cool because, if you zoom in, you’ll notice many stars of various sizes shining through the earth’s blue atmosphere - all captured during the daytime.

M31 | The Andromeda Galaxy I’m extremely excited to present my biggest deep sky imaging project yet. This is a 2 panel mosaic of the Andromeda Galaxy captured over 31 days in the later months of 2025. When I decided to image this object, I knew I wanted to try and resolve the Oiii arc as best I could, but the FOV using my Cat 91 scope and 2600mm camera was just a little too tight. A 2 panel mosaic was the next best option and even though that essentially cut my exposure time in half, I’m still pleased with how many of the interesting M31 features I was able to resolve. 

While I’m not too interested in the deep astro-physics related information about each of the targets I image, I did read up a little bit about the Oiii arc on its various discovery publications. I also read a little info on the hydrogen alpha clouds and learned that they are actually part of our own galaxy instead of M31. We are looking through a “galactic haze” made of red hydrogen clouds - super cool if you ask me!

Processing this image was an extreme challenge for me, and I was able to utilize some techniques I learned and developed while processing my Thor's Lightning image. See my Astrobin publication for a more detailed breakdown. If you take time to view the full resolution image on Astrobin and zoom around, you’ll find A TON of background galaxies along with some interestingly shaped structures inside M31’s halo as well. 
I hope you all enjoy this image and are having a great start to 2026! Clear Skies!

LDN 204 | The Dark Seahorse Captured this beautiful dark nebula that somewhat resembles a seahorse late this summer as the Milky Way was setting. This nebula is a collection of dense gas in Ophiuchus blocking the bright red hydrogen alpha emission nebulousity behind it. I hope yall enjoy this unique capture :) Clear skies!

C2025 K1 ATLAS visits the Leo Triplet This is a unique image that I'm excited I was able to capture late last year. The trajectory of Comet K1 ATLAS put it directly next to the famous Leo Galaxy Triplet on 6-8 November 2025, so I captured the comet images then and captured deeper exposures on the Leo Triplet later in March. The alignment here is exactly how it appeared November 8th, accomplished using StarAlignment and CometAlignment in PixInsight. Also, I'm grateful to share that this image was chosen as the Astrobin Image Of The Day today (14 September 2026)! Comet ATLAS was a very unusual comet in that it didn't have the standard green coma and blue tail of most comets. It lacked diatomic carbon molecules that ionize in sunlight to create a green coma. Instead it contained a higher ratio of water and hydroxyl compounds which gave it the gold hue. Super cool!

Sh2-1 | The Ghost of Scorpius I captured this region near the Rho Ophiuchi complex a few weeks ago and absolutely love how the mix of reflection nebulae, red hydrogen gas, and bright blue stars create such a dynamic field of view, rich with color.

M81 & M82 in a sea of IFN Excited to present this image of a region of the sky that I've wanted to properly capture for years. Going all the way back to 2020 when I tried imaging M81/M82 with my 135mm lens, stock DSLR, and bortle 4 skies, I was so excited to see the faint integrated flux nebula in the background start to show up after a few hours of integration. Fast forwarding to 2026, having several years of processing experience and gear upgrades under my belt, here is my latest capture. The new MARS survey integrated with the MultiscaleGradientCorrect process in PixInsight was the key to getting a high quality image out of this data. Without that powerful gradient correction, the IFN would have been buried in blotchy and complex light pollution gradients. Thanks to the PI team for their incredible work on this invaluable tool.

Coma Berenices Cluster This cluster is rarely imaged outside of wide field shots - I assume because it's not as visually striking as many other deep sky objects. But yall know me and that I love star clusters, so I took my 3D printed diffraction spike mask for a test spin and captured this image during one of the last full moon cycles. In the second slide, you'll see the diffraction spike mask that I designed, had 3D printed at my local library, and integrated with my telescope lens cover. The mask works like a charm and makes me miss imaging with my Newtonian :) If anyone wants the OpenSCAD model, shoot me a DM 30x120s RGB Cat91, 2600mm, Astronomik Deepsky RGB, CEM70 taken in Rockwood, Texas by @jdh_astro

M17 | The Omega Nebula A few days ago, I finished capturing this famous summertime nebula in narrowband SHO. It was my first time capturing it in something other than a wide field image and I'm really pleased with how the colors turned out. This time of year is epic for nebula imaging and I have many projects underway that I'll be excited to share more of soon. Clear skies! Cat91, ASI 2600mm, Astronomik RGBSHO, CEM70 by @jdh_astro

M104 | The Sombrero Galaxy I captured this object back in early spring with the goal in mind of revealing the faint tidal loop and halo. Due to awful weather and spring storms at the observatory, I wasn't able to capture the integration time I had originally planned, but the amount I had captured showed potential. Since I had moved onto other projects since spring, I decided to finally process the image and here is the result! For the relatively short integration time, I'm pleased with how the halo and loop turned out. I hope you all enjoy :) The full resolution will be on my Astrobin in the next couple days. Clear skies!!

M25 Cluster During the last full moon cycle, I captured this image of M25 embedded in a dense sea of over 150,000 stars from our own Milky Way galaxy. These Milky Way areas are some of my favorite to capture in the whole night sky and I love how all the individual stars blend together to form the golden canvas of the galactic core. Clear skies!

NGC 2170 | The Angel Nebula Checked this really unique object off my bucket list this past winter! The Angel Nebula is a complex nebula region made up of red emission nebulae and dark dust reflecting the colored light of nearby stars. The dust is so thick that it blocks starlight from behind it - this provides us astrophotographers with lots of visual depth to work with in our compositions. Now that I image in monochrome, as I take images, I don't see the color separation between these clouds and the background sky like I do with a colored camera. This makes the image stacking process even more exciting when you finally get to see the true depth of the dusty region you're capturing. I hope you all enjoy! Clear skies :) 18hrs total integration LRGB Cat91 / CEM70 / ASI 2600mm / Astronomik L-2 + RGB taken in Rockwood, Texas by @jdh_astro
