We didn't have clear skies down here in the southeast so my date with the blood moon will have to wait until the next time it comes around in October. In the meantime, here's a shot from the beach a couple of weeks ago. We were having 20+ mph winds that morning so the reflection in the pools was a little unclear, but there's some potential with this kind of shoot.

I could use some help.  I need to reorganize my portfolio and want to take into account popular opinion.  So if you can, please +1 your favorites while trying to limit yourself to 3 +1's.  And if you don't mind, please share so I can expand my reach to outsiders.  Thanks everyone!

No prob. That's just what I use, but you can certainly get away with some much less expensive camera bodies. I used a Canon T2i for awhile and it worked just fine.

Check it out, I actually found time to write up a blog post! If you're a landscape astrophotographer and want to read about my trials with removing vignettes from individual frames, this is what I found.

Parts of South Carolina and Georgia are protected from the Atlantic Ocean by a barrier of sea islands. One of these is Hunting Island near the southern end of South Carolina, in between Hilton Head and Charleston. I decided that the skies were right for an excursion, and so I headed out.

I chose not to use the campground on the northern end of the island and stuck to the south end where there was easy access to a pier, overnight parking, and a lot of trails that cut through the maritime forest and marshlands. After some quick research this morning, it looks like the ocean currents flow from north to south along the beach and the forest that inhabits a good portion of the island abruptly ends at the ocean on the southern end where the salty water feasts on the trees and uproots them.

April's calendar wallpaper is up, no foolin'! Muley Point is a hidden access road high above Goosenecks State Park in southeastern Utah. But it's not just Goosenecks State Park that you can see from this vantage point. There's also another slightly well known tourist area nearby... Monument Valley. You can see it deep within the image, all the way out near the horizon.

We stopped here to camp during a drive up to Colorado last August. Unfortunately, it coincided with a full moon and an overcast night, so the stars weren't that great. But, with this kind of vista, I didn't really care. And besides, you can still see the Milky Way in the center if you look closely.

Feel free to download the correct size for your desktop, share with friends and family, and of course enjoy!

Awesome. Thanks for the new wallpaper.

The cormorant. Why aren't they sports teams named after cormorants? It's such a cool sounding name.

Thanks to everyone for your much needed feedback, I'll be using it to reorder my images on my website soon. Now back to some regularly scheduled programming...

While waiting for the Milky Way to show up, I did a little light painting. Since I'm in the middle of moving across country, all of my flashlights are packed away in boxes somewhere, but I did have a cell phone. Unfortunately, I found that the camera flash on it was way too powerful and made close-up light painting difficult to control. So I pulled up a web browser page that was completely white and just hovered the screen over the subject for the length of the exposure. I moved it around to prevent any hot spots, but I found that it gave off the perfect amount of light for what I was trying to achieve.

Yesterday I shared a vertical panorama of the marshland on Hunting Island in South Carolina.  This is the horizontal panorama version of it.  Talk about a totally different feel.

Coming on the heels of yesterday's beach side of Hunting Island, here's my image of the marsh side. This would be an incredible area for a sunset shot, but I wasn't there in time. Anyways, this is a 4 shot vertical panorama, about 10,000 pixels high when viewed at full resolution. And as such, you might have to click on it to view the whole thing.

I was out on the beach early this morning doing what I do and was about to pack it in and head back home when I saw my 70-200mm f/4 lens sitting in my bag. Random thoughts later and I'm testing out the high ISO capabilities of my camera. Like really testing it out. I only spent about 12 minutes shooting with it, but was able to get enough data to put together this enormous panorama.

Details: 5 rows of 8-10 frames each (49 total). 4 sec, f/4, ISO 25,600. 19,000x13,000 pixels.

Lessons learned:
- High ISOs lead to big lens vignetting. At least I can't figure out how to remove the vignetting without introducing a lot of noise in the vignetted areas. And at 25,600, there was already plenty of noise. That's why you see all those dark circular areas.
- Hand stitching is a pain in the butt. 12 minutes of shooting and 8 hours of stitching. I need more processing power.
- Maybe it's time I dig out the Polarie and actually start using it.

Thanks +Darryl Van Gaal.  This whole sequence was just a brief afterthought to my morning and I didn't really think the process through.  I'm familiar with dark and bias frames, just have never used them in practice.  If I get out again next month to try real astrophotography, I'll definitely revisit the right way to do this.
