Olivier has been watching the sky since the mid- 1970’s and started imaging around 2003. In 2007 he built a roll-off roof observatory in his backyard mostly as a shield against car lights and to provide greater stability to the imaging train. He has been imaging out of that location since then and moved from a 4” apo refractor to his current 12.5” Hyperion astrograph.

  • Hubble Revisits the Veil Nebula 2 April 2021
    Image: Hubble revisits the Veil Nebula 2 April 2021 this stellar violence, the shockwaves and debris from the supernova sculpted the Veil Nebula's delicate tracery of ionized gas—creating a scene of surprising astronomical beauty. The Veil Nebula is also featured in Hubble's Caldwell Catalog, a collection of astronomical objects that have been imaged by Hubble and are visible to amateur astronomers in the night sky. Provided by NASA Credit: ESA/Hubble & NASA, Z. Levay This image taken by the NASA/ESA Hubble Space Telescope revisits the Veil Nebula, which was featured in a previous Hubble image release. In this image, new processing techniques have been applied, bringing out fine details of the nebula's delicate threads and filaments of ionized gas. To create this colorful image, observations were taken by Hubble's Wide Field Camera 3 instrument using five different filters. The new post-processing methods have further enhanced details of emissions from doubly ionized oxygen (seen here in blues), ionized hydrogen, and ionized nitrogen (seen here in reds). The Veil Nebula lies around 2,100 light-years from Earth in the constellation of Cygnus (the Swan), making it a relatively close neighbor in astronomical terms. Only a small portion of the nebula was captured in this image. The Veil Nebula is the visible portion of the nearby Cygnus Loop, a supernova remnant formed roughly 10,000 years ago by the death of a massive star. That star—which was 20 times the mass of the Sun—lived fast and died young, ending its life in a cataclysmic release of energy.

  • The Blue Hours Dusk, Early September, Just Beneath the Arctic
    The Blue Hours Dusk, early September, just beneath the Arctic Circle, by a tideline glacier in East Greenland. The cusp of the seasons, the cusp of the globe, the cusp of the land, and the day’s cusp too: twilight, the blue hours. At this latitude, at this time of year, dusk lasts for two or three hours. We have returned from a long mountain day: pitched climbing up steep slabs and over snow slopes to a towered summit, from which height we could see the great inland ice-cap itself. Then down, late in the day, the darkness thickening around us, and the sun dropping fast behind the western peaks. So we sit together back at camp as the last light gathers on the water of the fjord, on icebergs, on the quartz seams in the white boulder-field above our tents. Twilight specifies the landscape in this way – but it also disperses it. Relations between objects are loosened, such that shape-shifts occur. Just before full night falls, and the aurora borealis begins, a powerful hallucination occurs. My tired eyes start to see every pale stone around our tent not as boulder but as bear, polar bear, pure bear, crouched for the spring. Across the Northern hemisphere, twilight is known as the trickster-time: breeder of delusion, feeder of fantasies, zone of becomings. In Greek, dusk is called lykophos, ‘wolf-light’. In Austria, too, it is Wolflicht. In French it is the phase entre chien et loup, ‘between dog and wolf’: the time when, as Chrystel Lebas has written, ‘it is nearly impossible to tell the difference between the howling sound coming from the two animals, when the domestic and familiar transform into the wild.’ I do not know the Greenlandic word for dusk, but perhaps it would translate as ‘bear-light’.

The title used here, Midnight Sun, some of the chapter titles, and all the non-interior dialogue between Edward and Bella are copyright Stephenie Meyer. The first half of Ms. Meyer’s rough-draft novel, of which this is a continuation, can be found at her website here: http://www.stepheniemeyer.com/pdf/midnightsun_partial_draft4.pdf 12. COMPLICATIONSPart B It was well after midnight when I found myself slipping through Bella’s window. This was becoming a habit that, in the light of day, I knew I should attempt to curb. But after nighttime fell and I had huntedfor though these visits might be irresponsible, I was determined they not be recklessall of my resolve quickly faded. There she lay, the sheet and blanket coiled around her restless body, her feet bound up outside the covers. I inhaled deeply through my nose, welcoming the searing pain that coursed down my throat. As always, Bella’s bedroom was warm and humid and saturated with her scent. Venom flowed into my mouth and my muscles tensed in readiness. But for what? Could I ever train my body to give up this devilish reaction to my beloved’s smell? I feared not. Cautiously, I held my breath and moved to her bedside. I untangled the bedclothes and spread them carefully over her again. She twitched suddenly, her legs scissoring as she rolled to her other side. I froze. “Edward,” she breathed.

The Negro American has for his environment not only the white surrounding world, but also, and touching him usually much more nearly and compellingly, is the environment furnished by his own colored group. There are exceptions, of course, but this is the rule. The American Negro, therefore, is surrounded and conditioned by the concept which he has of white people and he is treated in accordance with the concept they have of him. On the other hand, so far as his own people are concerned, he is in direct contact with individuals and facts. He fits into this environment more or less willingly. It gives him a social world and mental peace. On the other hand and especially if in education and ambition and income he is above the average culture of his group, he is often resentful of its environilcg power; partly because he does not recognize its power and partly because he is determined to consider himself part of the white group from which, in fact, he is excluded.

  • George Orwell in His Centenary Year a Catalan Perspective
    THE ANNUAL JOAN GILI MEMORIAL LECTURE MIQUEL BERGA George Orwell in his Centenary Year A Catalan Perspective THE ANGLO-CATALAN SOCIETY 2003 © Miquel Berga i Bagué This edition: The Anglo-Catalan Society Produced and typeset by Hallamshire Publications Ltd, Porthmadog. This is the fifth in the regular series of lectures convened by The Anglo-Catalan Society, to be delivered at its annual conference, in commemoration of the figure of Joan Lluís Gili i Serra (1907-1998), founder member of the Society and Honorary Life President from 1979. The object of publication is to ensure wider diffusion, in English, for an address to the Society given by a distinguished figure of Catalan letters whose specialism coincides with an aspect of the multiple interests and achievements of Joan Gili, as scholar, bibliophile and translator. This lecture was given by Miquel Berga at Aberdare Hall, University of Wales (Cardiff), on 16 November 2002. Translation of the text of the lecture and general editing of the publication were the responsibility of Alan Yates, with the cooperation of Louise Johnson. We are grateful to Miquel Berga himself and to Iolanda Pelegrí of the Institució de les Lletres Catalanes for prompt and sympathetic collaboration. Thanks are also due to Pauline Climpson and Jenny Sayles for effective guidance throughout the editing and production stages. Grateful acknowledgement is made of regular sponsorship of The Annual Joan Gili Memorial Lectures provided by the Institució de les Lletres Catalanes, and of the grant towards publication costs received from the Fundació Congrés de Cultura Catalana. The author Miquel Berga was born in Salt (Girona) in 1952.

  • Family Portrait Sessions Frequently Asked Questions Before Your Session
    kiawahislandphoto.com Family Portrait Sessions Frequently Asked Questions before Your Session When you make an investment in photography, you want it to last a lifetime. Photographics has the expertise to capture the moment and the artistic style and resources to transform your images into works of art you’ll be proud to share and display. We want you to relax and enjoy the experience so all the joy and fun comes through in your portraits. If you have any concerns about your session, just give us a call or pull your photographer aside to discuss any special needs for your group. Relax, enjoy and smile. We’ve got this. Q: What should we wear? A: For outdoor photography on the beach, choose lighter tones and pastel colors for the most pleasing results. Family members don’t have to match exactly, but should stay coordinated with simple, comfortable clothing that blends with the beach environment. Avoid dark tops, busy patterns, graphics/logos, and primary colors that have a tendency to stand out and clash with the environment. Ladies, we’ll be kneeling and sitting in the sand so be wary of low necklines and short skirts. Overall…be comfortable. For great ideas visit our blog online. Q: When is the best time to take beach portraits? A: On the East Coast, the best time is the “golden hour” just before sunset when the light is softer and the temperature is more moderate. We don’t take portraits in the morning and early afternoon hours, because the sun on the beach is too intense which causes harsh shadows and squinting.
