North America Nebula and a Meteor

We had a break in the summer monsoon resulting in several nights of clear skies. I took advantage of the weather to do some astrophotography. I had a few targets in mind and settled on the North American Nebula and Pelican Nebula located in the constellation of Cygnus.

I ended up at Sunset Crater Volcano National Monument because of the very dark skies there (they are an International Dark Sky Park) and because of the nice parking lot for setting up the photography gear. Once everything was set up, I pulled out the camp chair and relaxed looking up at the sky while the camera was busy taking photos. While staring at the stars I saw a bright meteor move through the constellation Cygnus. Checking the camera I was happy to see that the meteor had been completely captured in the field of view.

I captured 77 images each 60 seconds in duration. After grading the images I ended up with 70 usable images for stacking. I used Starry Sky Stacker for the alignment and stacking and rnc-color-stretch for the post processing to bring out the colors and detail.

I’ve taken photographs of the North American Nebula twice before (2019, 2020) but this was the highest quality set of images and it had the meteor. A successful evening.

Launch of Firefly Alpha FLT005

The 5th flight of a Firefly Alpha rocket was launched from Vandenberg Space Flight Base last week (03 July 2024). This was the first time I had observed a Firefly launch and was not certain what to expect. I started photographing the launch using a telephoto (80mm) but a few minutes into the flight I realized I needed a wide-angle lens (12mm) to fully capture the rapidly expanding rocket exhaust.

I manually tracked the flight and captured a few more images in which the 1st stage and fairings can be seen.

Using the wide angle lens I was able to capture a sequence of images suitable for time lapse, presented below.

As noted above, I switched from a telephoto lens to wide angle lens a few minutes into the flight–thus the time lapse starts well after launch. Nonetheless, the rapidly expanding rocket exhaust shows up well. Also, there is a hole punched in the ionosphere causing it to glow red. This video was featured on Spaceweather.com and a description of the red glow was provided:

The lingering red glow is “the hole.” Earth’s ionosphere is a layer of electrically-conducting gas enveloping our planet more than 100 km high. It plays a key role in shortwave radio communications and GPS positioning. When Alpha burned through the ionosphere, water and carbon dioxide in therocket’s exhaust quenched local ionization by as much as 70%. Red light is the afterglow of this process.

It was spectacular to watch and photograph. As always, I look forward to additional launches from Vandenberg SFB.

An Early but Brief Start of the Monsoon

The North American Monsoon got an early start in northern Arizona this year with copious amounts of precipitation over the San Francisco Peaks and surrounding areas. Unfortunately, we are now experiencing an extended monsoon break with mostly clear skies and hot temperatures.

Here are some photograph taken during that wet period.

Sedona Moonrise–June 2024

/ 1 Comment

It is the season for capturing the nearly-full Moon as it rises behind Cathedral Rock in Sedona, Arizona. The best time to capture this is a day (or two) before the actual full Moon so that late afternoon sunlight still illuminates Cathedral Rock. The Photographers Ephemeris (TPE) was used to determine the best location to shoot this as it became visible between the towers.

Unfortunately, there was a major dust storm the day and dust remained in the air partially obscuring the Moon at lower elevation angles. The Moon got brighter as it rose higher in the sky.

And here is a time-lapse sequence of the Moon rising.

Bonus:

Here is additional Moon photograph taken at Upper Lake Mary near Flagstaff in early June. I was going for the reflection.

Milky Way and a Fisheye Lens

I have taken countless photographs of the Milky Way using anything from ultrawide to telephoto lenses. But I have never taken a photograph of the Milky Way with a fisheye lens until now.

I like the result because it shows a large part of the Milky Way from south of the Galactic Center northward almost–but not quite–to Cassiopeia. Cygnus can be seen in the center.

As a bonus there is some banded airglow along the eastern horizon.
