Ten-Years Ago Today. Poppies and Lupines at Christ Church Cathedral, Stanley. (22-Dec-2014, Falkland Islands)

Silhouettes of an Airplane and Jets Passing in Front of the Sun.

Today, I captured images of an airplane and several jets transiting the sun while looking at the sunspots (we are at or near the solar maximum). I was observing the sun with a Vespera Classic and a Vespera Pro telescope each fitted with a solar filter. The exposure time for solar observations with the Vespera Classic telescope is 250 microseconds (1/4000 sec) and with the Vespera Pro telescope is 1400 microseconds (1/714 sec). The Vespera Classic takes 51-52 solar images per minute and the Vespera Pro takes 8-9 solar images per minute.

Comet C/2023 A3 (Tsuchinshan–ATLAS)

The comet is getting fainter and the tail much shorter. You may need to look closely; the comet is in the center of the frame. The magnitude is now 10.9. The slideshow displays the 32nd, 64th and 96th stacked composite image (5 min 20 sec, 10 min 40 sec, 16 min). In the last two images there is some movement of the comet head.

Ten-Years Ago Today. Magellanic Penguins (Spheniscus magellanicus) on New Island. (21-Dec-2014, Falkland Islands)

Winter Solstice Walkabout after the Snowstorm.

The snow ended and the sky cleared soon after sunrise. I set up the telescopes to observe the sun then went for a walkabout around the yard. The snow was a light powder that I was able to easily clear the driveway with a leaf blower. The tractor and the snow blower are ready but weren’t needed this time.

Images taken with a Hasselblad X2d camera and 38 mm f/2.5 lens. Individual images in the slideshow are available in my PhotoShelter Gallery.

Fifteen-Years Ago Today. Rainbow over Maui. (20-Dec-2009, Hawaii).

Trolls Out Celebrating the Winter Solstice.

I set up a camera looking out the backdoor window to take images for a time-lapse video of the snow accumulating on a set of Trolls. The prediction was for 2 inches. By morning there was between 4 and 6 inches of accumulation. The snow was light and fluffy. I didn’t need to start up the snow blower to clear a path to the driveway. I just used a battery powered leaf blower.

Apple-Cranberry Crisp

I had some Cranberries and Apples remaining from the last Fairgrown Farm CSA delivery. I used them to make a Crisp using a recipe modified from making an Apple-Pomegranate Crisp.

Fifteen-Years Ago Today. Nakalele Point Blowhole, Maui Hawaii. (17-Dec-2009)

Silhouettes of a Jet Passing in Front of the Sun.

Today, I captured an image of a jet passing in front of the sun while looking at the sunspots (we are at or near the solar maximum). I was viewing the sun with a Vespera Passengers telescope fitted with a solar filter. The exposure time for solar observations with the Vespera Passengers telescope is 300 microseconds (1/3333 sec). The Vespera Passengers takes ~30 solar images per minute. Over an hour that amounts to 0.54 seconds (or 0.015% of the time). I am not sure why the background of the image is blue. Previous observations the background was black and the sun orange. I will be contacting Vaonis support about the strange colors.

The comet is getting fainter and the tail much shorter. You may need to look closely; the comet is in the center of the frame. The magnitude is now 10.7. The first image is a composite of 32 images (5 min 20 sec) and the second one is a composite of 128 images (21 min 20 sec). In the second image there is some movement of the comet head.

Fifteen-Years Ago Today. Surfer Girl at Hookipa Beach Park. (16-Dec-2009, Maui)

Image of the Day.

For the image of the day, I select an image from the past taken on this day of the year. I now have over a million digital images going back to 2006 when I got my first DSLR camera, a Nikon D200 for a cross-country road trip. I have a few other digital images from a Polaroid PDC 700 point and shoot from before 2006.

The “Surfer Girl” image was taken while in Hawaii for a Pacific Chemistry scientific meeting. I had the morning off and went for a drive along the coast. I stopped at Ho’okipa Beach Park and went to a section overlooking the beach. It was windy and there were some big waves. I could see some folks surfing the waves at a distance of 300-400 feet. For the trip, my travel camera was a Nikon D3x with a 70-300 mm zoom lens. At that time the 24-megapixel sensor was state of the art — great for landscapes or portraits with a steady tripod. But it was slow, not really suited for fast moving sports. Maybe 2 shots/second burst rate that quickly filled the buffer. I took a number of shots of the surfers out on the big waves.

It wasn’t till I downloaded the images later that evening that I realized I captured this great shot out of a 15-shot sequence taken over 8 seconds. Having a 24-megapixel image allowed me crop and zoom in on the surfer. I posted a cropped image on my photoblog and on Google+. A print of the image won an award at a Photography Show in Florida. I posted it on my photoblog and on Google+. Later, I found out it ended up in some surfer sites and it had been used in time-share and condo rental advertisements. Probably, my most stolen image.

Below, I show the original image sequence along with reprocessed versions of the sequence with currently available tools. DxO Pure Raw (Camera/Lens correction), Capture One Pro (Levels and High-Dynamic Range), and Topaz AI (sharpening).
