There are several methods that nightscape photographers use to ensure that the stars in our photos are sharp–“tack-sharp” as the worn-out term goes. After several years of trying my best to get those incoming photons to be pin-pricks, it was hard for me to shoot a photo like the one I’m posting today, in which the stars are intentionally OUT of focus!
For my in-focus foreground element, I chose one of the more recent monuments in the Tangmangaroo Anglican Church’s graveyard–near Yass, Australia–with the rising Milky Way’s core blurred, but still colourful, in the background. I focussed on the distinct straight edges of the cross and its plinth, setting my lens to its shallowest depth-of-field to maximise the sky’s fuzzy look.
I used the following equipment and settings to create this image: Canon EOS 6D camera, fitted with a Sigma 35mm f/1.4 Art lens @ f/1.4 aperture, choosing an exposure time of 10 seconds @ ISO 1600.
[Legacy Photo] This was the first and only time I've seen and photographed an adult Eared Grebe in full breeding plumage. The photo was taken at small lake near Klamath Falls Oregon in the spring of 2014. The water effect was created by a combination of a shaded pond that was surrounded by a very green forest and a subtle breeze..

What a show! Super vagrant from Europe/Asia/Africa. I just switched from a Tamron 150-600 1G to the Nikon 500mm pf prime, about 10 days ago. I miss the balance and solid feel of my Tambam, but this lens is super sharp and colorful, light, and the one I've now kept attached to my D500 body.
Another fruitful day of mostly NCT spotting was to be had, with a return to Mansfield Road and a bit of a brown line theme developing too, as I ventured up to the hospital. Of course, other stuff was around too, including the first phot on the 'proper' camera, which was Sharpes Van Hool T9 coach 7 JXO turning out of Woodborough Rd and up Mansfield Rd.

I was cleaning up the backlog on my computer and found this shot with the hawk's nictitating membrane partially closed.
The "Sharps Island Lighthouse" originally stood on an island of over 4,000 acres. The first light, built in 1838, was moveable. In 1866 a screwpile lighthouse was built but was destroyed by ice in 1881. The present 54 foot high iron tower on a concrete-filled caisson was built in 1882 and was painted purple. It is now a more traditional brown, and while it has begun to tilt, it has survived Sharps Island which has completely disappeared.
I drew from a greeting card published by Heritage Art Publishers, Inc. Easton, Maryland. The original watercolour painting is by Ann Clotworthy Charlton, a resident of St. Michaels, Maryland.
Try to work on my watercolour. Copy from the greeting card but cannot get the blue in the sky and sea correct.
Another shot of the Red Kite - this time it was getting ready for a landing and the claws came out...... I couldn't believe the length and sharpness of those talons.
Thanks for the views, comments and faves :)
have a great Wednesday :)
Happened in my back yard a couple of years ago. This bird sat on the log and finished the meal over a two-hour period. It was interesting to watch it pull and tug away the bite-sized pieces.
I came across 4 sharp tailed grouse today. Unfortunately I had too much lens on (not a problem I'm used to), and could not back up and keep the birds in view.
They survive the extreme cold, by borrowing into the snow at cold temps. A few days ago, I saw one with just its head out of the snow, as I approached to investigate, the snow exploded into flying grouse.
You can also see the feathers on the feet to keep them warm even when they are about in the cold.
These shorebirds make their way from Alaska to their wintering grounds in Australia every fall, with some ending up stopping in Hawai'i along the way.

Photographed out my back window while perched in an apricot tree about 20 feet from me. Photographed through window glass so not the best quality. I think he/she knows I am watching. IMG_0071
This Chandra image shows the Carina Nebula, a star-forming region in the Sagittarius-Carina arm of the Milky Way a mere 7,500 light years from Earth. Chandra's sharp X-ray vision has detected over 14,000 stars in this region, revealed a diffuse X-ray glow, and provided strong evidence that massive stars have already self-destructed in this nearby supernova factory.
The lower energy X-rays in this image are red, the medium energy X-rays are green, and the highest energy X-rays are blue. The Chandra survey has a large field of 1.4 square degrees, made of a mosaic of 22 individual Chandra pointings. In total, this image represents 1.2 million seconds -- or nearly two weeks -- of Chandra observing time. A great deal of multi-wavelength data has been used in combination with this new Chandra campaign, including infrared observations from the Spitzer Space Telescope and the Very Large Telescope (VLT).
Several pieces of evidence support the idea that supernova production has already begun in this star-forming region. Firstly, there is an observed deficit of bright X-ray sources in Trumpler 15, suggesting that some of the massive stars in this cluster were already destroyed in supernova explosions. Trumpler 15 is located in the northern part of the image, as shown in a labeled version, and is one of ten star clusters in the Carina complex. Several other well known clusters are shown in the labeled image.
The detection of six possible neutron stars, the dense cores often left behind after stars explode in supernovas, provides additional evidence that supernova activity is ramping up in Carina. Previous observations had only detected one neutron star in Carina. These six neutron star candidates are too faint to be easily picked out in this large-scale image of Carina.

It flew into our living room window this afternoon so while it was regaining it's composure I ran got my camera and clicked off a few.
I took this from the van and so far away that I thought it was a Robin because it looked reddish on the breast. Surprised me when I enlarged it on my desktop!
Sunshine today, out the wind a beautiful day, the sharp north easterly just taking the edge off it.

The most lovely falcon that I ever saw in my life. She is a young female kestrel (the smallest falcon : length 20cm, weight 103-160 g, wingspan 50-60cm) . She comes spontaneously to me and my daugther. She follows us and plays with us, we only have to be careful with their claws (a little too sharp), for the rest, no problem! She's so adorable...
Cómo me gustaría llevármela a casa...!! Sí, ya sé, eso no se hace... y eso que ella vendría la mar de a gusto... Pero ya sabéis, eso NO se hace! no no no....!! Que no!
