This past weekend was rainy and windy. Boredom set in. This was the result--San Francisco reduced to Marvel Comic status. Such a poor fate for such a beautiful city.

I shot this photo at the conclusion of a weekend iPhone/iPad Artistry workshop that was given at a local artists’ guild in CT. The workshop was held in the front part of an art room generally used for non-photography art classes While loading up my iPhone, iPad, pencils and notes at the conclusion of the digital workshop, I noticed the ancient skeleton and old wooden easel in the back part of the same art room. It struck me how different were the apparatuses used in drawing, painting, etc. from those I use in the digital photography world. I was also struck by the way a painting student studies her medium versus the way a digital photography student like me studies mine. For each of us, however, we study our “Art” as Reduced to its Minimum Form. I used Snapseed for basic cropping and DistressedFX for a moody, minimal look.

It's said that witnessing comet NEOWISE is a once in 6,800 year event, however, what does it mean if you can see it multiple times over the course of a month? Is it still "once in a..."???? Willie and I went out on multiple occasions to photograph the comet, both when it was visible at sunrise and when it was visible at sunset.

 

The comet NEOWISE was first discovered on March 27, 2020 by the WISE space telescope. It consists of 2 tails, one of which is blue and made of of gas and ions (called the "ion tail") and the second, which is made up of dust (the "dust tail"). Apparently a third tail was observed, which is a sodium tail. The first 2 tails (ion and dust) are visible here.

 

We made a few sunset attempts to see the comet but we were flustered by smoky skies from a fire a few hours south. A few friends had taken some amazing photos from Marin and we decided we would shlep up there one evening.... but I had an idea that we might be able to see it from Windy Hill Open Space Preserve in Portola Valley, so the night before our Marin outing, we set off to see if we could skip driving 2 hours north. Sure enough we were in for a treat. At sunset the fog came in and created a beautiful foreground for witnessing the comet descend. The fog also blanketed the Bay Area, reducing some of the light pollution that would have washed out the comet. Instead we got a beautiful view of the sky. I strapped on a new 105mm f/1.4 lens so I could get the most amount of light in, and we were treated to this stunner.

 

This is a combination of an ~85mm foreground photo with the 105mm sky photo. Yes, this is a composite (I'm not a lier or a hider of the truth).

Sorry about the speckled windscreen!

The beaver has been extinct in the UK since the 16th century, however up and down the land there are now numerous reintroduction projects. Apart from the wish to see the introduction of a large mammal back into our countryside there are now strong arguments that the beaver through its dam creation will help transform many of our smaller rivers. It is expected that by building the dams the flow of water will reduce after heavy rain and therefore gradually release the run off rather than produce the deluge we often see. Of course dam creation creates ponds and floodplains which in turn will have a knock on effect on the environment. There is one such designated release area not too far from me but I have yet to see the star attractions.

 

This photo was taken on our recent American trip in Oregon close to the coast at Barview which is just north of Tillamook. I should have expected we might have struck lucky as Oregon is known as the "Beaver State".

 

I had spotted somewhere to photograph a heritage diesel service and whilst I waited the beaver appeared. Alas I only had my standard lens to hand. The diesel passed, I got my shot and returned to the car to grab my long lens. This time Shirley accompanied me and for once was pleased I had stopped for a railway photograph. Thankfully it was quite active and reappeared a couple more times. Clearly it was an industrious individual.

Slender-tailed meerkat

Scientific name: Suricata suricatta

  

Meerkats live together in large communities and are very friendly towards each other. They work as a group to look out for one another, with some meerkats being posted as lookouts to watch for predators and others being used to hunt prey or nurse the pups.

 

Often pictured ‘standing up’ on their rear legs, these inquisitive creatures are alert to every movement around them.

 

The dark patches around their eyes help to reduce the glare of the sun, making them even more effective lookouts. They communicate by chirping and make shrill sounds to warn each other of potential dangers.

Gasteracantha cancriformis (spinybacked orbweaver) is a species of orb-weaver spider (family Araneidae). It is widely distributed in the New World.

 

The genus name Gasteracantha derives from the Greek words γαστήρ (gaster, "belly") and ἄκανθα (acantha, "thorn"), while the specific epithet cancriformis derives from the Latin words cancer ("crab") and forma ("shape, form, appearance").

 

Females are 5–9 mm (0.20–0.35 in) long and 10–13 mm (0.39–0.51 in) wide. The six abdominal spine-like projections on the abdomen are characteristic. The carapace, legs, and underside are black with white spots under the abdomen. Variations occur in the colour of the upperside of the abdomen - a white or yellow colour with both featuring black spots. A white upper side can have either red or black spines while a yellow upperside can only have black ones. Like with many other spiders, males are much smaller (2 to 3 mm long) and longer than wide. All morphs have six abdominal spines. They are similar to the females in colour, but have a gray abdomen with white spots and the spines are reduced to four or five stubby projections.

 

This species of spider does not live very long. In fact, the lifespan lasts only until reproduction, which usually takes place in the spring following the winter when they hatched. Females die after producing an egg mass, and males die six days after a complete cycle of sperm induction to the female.

Northamptonshire, where we live, is perhaps one of the least known counties in England despite the fact that the M1 and the A14 pass through it. It is a rural county with rich farmland and the remains of two large medieval forests. There are only half a dozen large towns, of which the largest is Northampton itself, several miles to the south of here.

 

Formerly known as a shoe and leather producer, and for its iron and steel industry based mainly at Corby, Northamptonshire is now mainly a light industrial and storage and distribution centre with vast warehouses either lining or close to the main through routes. It has also been required to build vast new housing developments to help reduce the housing problem in the south-east of England.

I made a send out to the northeast piedmont region to shoot CSX's northbound Norlina Sub local L617. CSX made the very intriguing decision to start sending MP15ACs 1136 and 1186 for local service in the Raleigh area over the past couple months. Being the whore for endcab switchers that I am, I knew I finally had to get this operation under my belt. The power on L617 this day was a pretty cool trio of 4 axle EMDs. The leader is one of the new GP40-3 rebuilds done by MEI earlier this year, with 1186 second out and an original square cab GP38-3 in the third slot. I don't like that the new dash 3s recieve e-bells, but they do look pretty good. Here's the local flying over the massive Tar River bridge south of Kittrell, with the access road for Carolina Sunrock winding beneath it. You can see one of the original bridge's supports beneath the newer structure. It's really crazy to think about how this used to be a busy mainline with high speed piggyback and passenger trains up until the 1980s, now reduced to getting a pair of 20 mile per hour locals only on weekdays. That'll soon change though, with plans for the entire S Line from Raleigh to near Richmond to be rebuilt to host 120 mile per hour Amtrak service. I'm happy I was able to shoot this line before that change happens.

At the worst of the afternoon snow yesterday.

We had an accident in January on the Crooked River in Westland.

After a steep descent from the bush to the river, Kathryn was climbing around an obstacle in the river and her binoculars pouch strapped to the chest, which held the camera at the time, flipped open and the camera was lost in the river.

I tried fishing around with the walking pole in white water to catch the lanyard. It was impossible to see and it likely slipped down between boulders anyway. The loss of the SD card was regrettable because of the images it held.

Maybe it makes her kit lighter today but the iphone is no comparison to the what the camera could do.

Reduce your Stress

The theme for this week's Macro Mondays is "plastic". I became very aware of the issue of single-use plastic contaminating our oceans on visiting uninhabited areas of eastern Greenland last year and taking part in a beach clean-up - we collected dozens of items of throwaway plastic. It has become big news this year with the UK's proposal to ban plastic straws and cotton buds. For my macro entry I decided to take a picture of my water bottle, which I now use instead of buying bottled water - saving a lot of money as well as doing a small bit to save our oceans. So - this is "Plastic" for Macro Mondays. HMM! (field of view is under 2 inches)

 

And doubling up - my Day 23 entry for April 2018: A month in 30 pictures, and #23/100 for 100 x: The 2018 Edition - my x is macro with a dedicated macro lens.

I shot this from the hotel in Boerne where we took refuge after losing all delivery of power and water at the house.

The Sand Island Lighthouse (also known as the Sand Island Light) is located approximately three miles south from Mobile Point. Originally located on a low lying island of 400 acres, the light stands surrounded by water and massive stones placed to halt the erosion of the island. The tower, which is influenced by the Italianate style, is a 132 foot conical masonry structure which tapers from a width of 40 feet at the base to 17 or 18 feet at the top. It rests on a foundation consisting of double course of sill timbers resting on one hundred seventy-one piles overlaid with 12 feet of concrete. Constructed in 1875, Sand Island Lighthouse is the older of the two remaining lighthouses in the state and is the third to have been erected on this location. A light at Sand Island has marked the entrance to Mobile Bay & the Mobile Ship Channel since 1838. This was the second navigational aid erected for the entrance to the port of Mobile, a light having been established at Mobile Point in 1822. The Frensel lens which has been removed was constructed by Barier and Fenestri in Paris in 1871. Since the construction of the tower several different systems were used for lighting. Originally lard oil lamps were used but were replaced in 1833 by mineral oil lamps. In 1912 an incandescent oilvapor lamp of 17,000 candlepower visible 18 miles at sea was installed and later replaced in 1947 by four nine inch 1000 watt bulbs when the light was automated in 1947. In 1966, the 60,000 candle power beam was dimmed to 8,000 when the new Mobile Point Light took over. The light was finally extinguished and the structure abandoned in 1971. The lens was removed at this time and moved to the nearby Fort Morgan Museum. In 1973, the keepers house was burned. The island were the Sand Island Lighthouse was built, originally 400 acres, had been eroding since the construction and by 1873 was reduced to less than 100 acres. The erosion continued at a rapid pace until between 1873 & 1902 the keepers dwelling was twice removed to more stable ground and several thousand tons of rock were placed around the island & tower. More recently, restoration efforts resulted primarily in stabilization of the island through 2008 and in December 2011 construction of a new island was completed with 1,400,000 yards of sand being dredged from the sea floor and deposited around the lighthouse creating a 2,600 feet by 500 feet, or approximately 15 acres island. Less than a year later the $6,000,000 restoration of the island was washed away by Hurricane Isaac.

Ochsenfurt (German: [ˈɔksn̩ˌfʊʁt]) is a town in the district of Würzburg, in Bavaria, Germany. Ochsenfurt is located on the left bank of the River Main and has around 11,000 inhabitants. This makes it the largest town in Würzburg district.

 

Like Oxford, the town of Ochsenfurt is named after a ford where oxen crossed the river.

 

The town is situated on the left bank of the River Main, 21 kilometres (13 mi) south of Würzburg.

 

Ochsenfurt was one of the places in Germany where King Richard I of England was detained in 1193 while on his way to England from the Third Crusade.

 

A monastery, Tückelhausen Charterhouse, dedicated to Saints Lambert, John the Baptist, and George, was founded in 1138 by Otto I, Bishop of Bamberg, as a double canonry of the Premonstratensians. From 1351 it belonged to the Carthusians and was secularised in 1803.

 

The charterhouse was largely converted for private residential use and since 1991 contains a museum of Carthusian life.

 

Ochsenfurt also features several Protestant and Roman Catholic churches, among them that of St Michael (Michaelskapelle), a Gothic edifice.

 

In 1911 there was a considerable trade in wine and agricultural products, other industries being brewing and malting. Ochsenfurt also has one of the largest sugar factories in Germany.

 

Lower Franconia (German: Unterfranken) is one of seven districts of Bavaria, Germany. The districts of Lower, Middle and Upper Franconia make up the region of Franconia. It consists of nine districts and 308 municipalities (including three cities).

 

After the founding of the Kingdom of Bavaria the state was totally reorganised and, in 1808, divided into 15 administrative government regions (German: Regierungsbezirke, singular Regierungsbezirk), in Bavaria called Kreise (singular: Kreis). They were created in the fashion of the French departements, quite even in size and population, and named after their main rivers.

 

In the following years, due to territorial changes (e. g. loss of Tyrol, addition of the Palatinate), the number of Kreise was reduced to 8. One of these was the Untermainkreis (Lower Main District). In 1837 king Ludwig I of Bavaria renamed the Kreise after historical territorial names and tribes of the area. This also involved some border changes or territorial swaps. Thus the name Untermainkreis changed to Lower Franconia and Aschaffenburg, but the city name was dropped in the middle of the 20th century, leaving just Lower Franconia.

 

From 1933, the regional Nazi Gauleiter, Otto Hellmuth, (who had renamed his party Gau "Mainfranken") insisted on renaming the government district Mainfranken as well. He encountered resistance from Bavarian state authorities but finally succeeded in having the name of the district changed, effective 1 June 1938. After 1945 the name Unterfranken was restored.

 

Franconia (German: Franken, pronounced [ˈfʁaŋkŋ̍]; Franconian: Franggn [ˈfrɑŋɡŋ̍]; Bavarian: Frankn) is a region of Germany, characterised by its culture and Franconian dialect (German: Fränkisch).

 

Franconia is made up of the three Regierungsbezirke of Lower, Middle and Upper Franconia in Bavaria, the adjacent, Franconian-speaking, South Thuringia, south of the Thuringian Forest—which constitutes the language boundary between Franconian and Thuringian— and the eastern parts of Heilbronn-Franconia in Baden-Württemberg.

 

Those parts of the Vogtland lying in Saxony (largest city: Plauen) are sometimes regarded as Franconian as well, because the Vogtlandian dialects are mostly East Franconian. The inhabitants of Saxon Vogtland, however, mostly do not consider themselves as Franconian. On the other hand, the inhabitants of the Hessian-speaking parts of Lower Franconia west of the Spessart (largest city: Aschaffenburg) do consider themselves as Franconian, although not speaking the dialect. Heilbronn-Franconia's largest city of Heilbronn and its surrounding areas are South Franconian-speaking, and therefore only sometimes regarded as Franconian. In Hesse, the east of the Fulda District is Franconian-speaking, and parts of the Oden Forest District are sometimes regarded as Franconian for historical reasons, but a Franconian identity did not develop there.

 

Franconia's largest city and unofficial capital is Nuremberg, which is contiguous with Erlangen and Fürth, with which it forms the Franconian conurbation with around 1.3 million inhabitants. Other important Franconian cities are Würzburg, Bamberg, Bayreuth, Ansbach and Coburg in Bavaria, Suhl and Meiningen in Thuringia, and Schwäbisch Hall in Baden-Württemberg.

 

The German word Franken—Franconians—also refers to the ethnic group, which is mainly to be found in this region. They are to be distinguished from the Germanic people of the Franks, and historically formed their easternmost settlement area. The origins of Franconia lie in the settlement of the Franks from the 6th century in the area probably populated until then mainly by the Elbe Germanic people in the Main river area, known from the 9th century as East Francia (Francia Orientalis). In the Middle Ages the region formed much of the eastern part of the Duchy of Franconia and, from 1500, the Franconian Circle. The restructuring of the south German states by Napoleon, after the demise of the Holy Roman Empire, saw most of Franconia awarded to Bavaria." - info from Wikipedia.

 

Summer 2019 I did a solo cycling tour across Europe through 12 countries over the course of 3 months. I began my adventure in Edinburgh, Scotland and finished in Florence, Italy cycling 8,816 km. During my trip I took 47,000 photos.

I got to this specific location below Hamilton, MT thanks to a dear photo-buddy a few autumns ago and was, and still am, very grateful for the tip. By the fall season, the Bitterroot River is usually very low, owing to many factors, and its usual vibrancy is reduced to a crawl. Nonetheless, that natural and seasonal transformation does nothing to reduce its beauty and its charm.

Being surrounded by the colors of autumn, and backed by the majestic Bitterroot Mountains, does not hurt the cause either. Quite the contrary.

Following the re-introduction of front door boarding, the maximum capacity of buses has changed due to social distancing. Therefore, even though this bus normally has a maximum capacity of 57 and has 31 seats, it can now only carry 10 passengers. Metroline West ADL Enviro200 DEL2145 (LK65EAA) shows off the new features whilst out on the 331.

Located in the seaside town of Sidmouth, Devon. The Radway Theatre opened as a live theatre on 25th June 1928. It was designed by local architect P.E. Steadman. Seating was provided for 680; there were 520 seats in the stalls and 160 seats in the circle. The proscenium was 27 feet wide and the stage was 22 feet deep, with four dressing rooms. The auditorium ceiling is made of patterned pressed tin, an unusual material to use in the UK, especially in a cinema.

 

Soon after opening, talking pictures arrived and the theatre was converted into a full time cinema, to the plans of noted cinema architect William Henry Watkins. Little alteration was done to the auditorium, it was mainly the foyer area alterations and provision of a projection suite that he was responsible for. It re-opened as the Radway Cinema on 2nd December 1929 with Estelle Brody in "Kitty". In 1936 it was re-named Palace Theatre, but went back to its original name the next year.

 

In the 1950’s a wider 41 feet proscenium was installed and the seating capacity was reduced to 365. The cinema was closed in 1984 for modernisation and re-opened 17th August 1985 with "A Passage to India" under the current operator. Closed for further improvement in March 2000, the cinema currently seats 270.

The trains run on reduced schedules, but they are still running. - Side effect of having much less traffic is probably running truly on time.

Had half a clear night the other night (albeit with a 90% moon) for the first time since the beginning of October which gave me time to do this. I was hoping to do Olll in the same session but after 2 subs the clouds rolled back in, so that's on the back burner.

The Dumbbell (or Apple Core) Nebula

 

Planetary nebula Messier 27 - a shell of fluorescing ionised hydrogen (red) and ionised oxygen ( green/blue) surrounds the remnants of a once active star - probably not unlike our own Sun. The white dwarf remnant star can be seen at the centre of the nebula.

 

The hard UV light from the white dwarf makes the surrounding ionised gases fluoresce in characteristic colours. The clouds of gas were probably shrugged off the star in the final phases of its life.

 

Deeper images show further shells of gas which are just hinted at here.
