All what you miss with a light polluted sky
Make the invisible visible: 30 second long exposure of Zurich night sky with the fast wide angle Sigma 14 mm f/1.8
Facing West, do you see Corona Borealis and Arcturus (Bootes)?
The milky way above Zurich city, light pollution high to very high – level (SQM) up to 18.89 mag./arc sec2
Facing North, do you see Ursa major, Ursa minor, Perseus, Giraffe, Cassiopea and much more ?
Jupiter and its 4 moons, do you see all the 4 of them? (shot with a 70-200 mm objective)
Facing West, do you see the Andromeda constellation and its galaxy?
If you did not see the constellations, click here 🙂 Wide angle pictures shot with SIGMA 14 mm f / 1.8, 30 seconds, ISO 1250. Jupiter shot with 200 mm f / 2.8, 0.4 second, ISO 400. Click each picture to zoom in.
Freeze! My first Deep Space Objects
Starry night skies are present in Zurich despite the light pollution . Still, is light pollution low enough for shooting deep space objects? Which exposures / f values, ISO combinations are necessary to capture galaxies or star clusters?
With a fixed tripod, 30 sec exposures cause long star trails.
With a Skyguider Pro mount, 4 minute long exposures produce clear star pins: so many stars turn visible through photography!
With such long exposures, Deep Space Objects like M37, Spinwheel and Starfish star clusters got visible! Can you see them between Venus (bottom left) and Capella (the bright star on the right border)?
Here is a crop from above: the 3 clusters are vertically displaced across middle of the picture.
A continuous tracking of the Polar Star alignment is useful with 4 minute long exposures or longer. If the alignment get lost during the shooting, star trails will appear. I obtained continuous tracking by changing the optical scope for iPolar, an electronic scope which shows the alignment to the Polar Star on a laptop screen. The electronic scope does not need to detect the Polar Star. The detection of 3-4 stars is enough to localize the Zenith. A good alignment is very easily kept for 4 minutes and likely more.
Camera setup for stars: 240″, f/3.2, ISO 500
Around 20 pictures stacked with the free software DeepSkyStacker
Lenses: Nikon 70-200 mm or 35 mm

Urban astrophotography
To the Moon and beyond with Skyguider Pro (iOPTRON)! I was gifted with this star tracker (thanks Maria Francesca!) for long night exposures. Are Zurich nights dark enough for testing it? Click each picture to open full-size pictures.

Repetita juvant
From Latin, repetita juvant : “the choice to repeat some important piece of information to ensure reception by the audience.” In photography, the repetition of objects for creating patterns or concepts.

Traces of Industrialization in Canton Glarus: the upcoming ARTBorghi photo exhibition
In Canton Glarus (Switzerland), narrow valleys and mountain peaks are the natural background to dozens of high-tech and traditional industries. Flat, geometric surfaces of metal and concrete hiding the landscape from the sight are far from being alien to the place: instead, they decorate it for hundreds of years. Industrial buildings often comprise large transparent surfaces, either glass windows or see-through structures: this mirroresque game merges natural and man made landscapes, which become indistinguishable one from each other. Industrial tools and products, steel bars and concrete pipes pop up from grass fields and courtyards in every corner of the valleys, again witnesses of the productivity and labor of Glarnerland. These activities are constantly carried on inside new and old walls, such as in Eternit of Niederurnen and many others.
From 29.9 (6 pm) to 9.10.2016 (6 pm) I will take part of a collective photo exhibition in Zürich. My thema Berg und Tal depicts what is on the top (mountains) and on the bottom of the valleys in Canton Glarus. Come to Photobastei for the vernissage or finissage to meet the photographers! Click on the flyer for more info (in German) or just write me at artborghi@gmail.com

Lisbon Story: enjoy its details in UHD
Shooting panorama requires sharp lenses and high resolution. A 36 Mpx camera with a 50 mm lens can make the trick. The pictures below are 100% crops of the first picture, the full panorama . Enjoy Lisbon from the terrace of Santa Justa.
Click to open in a new window and click again to zoom in the 9 MB panorama to enjoy its 17,000 px width.

How to merge full-res pictures for producing up to 50-picture-wide stitched-panorama
Click each panorama to open it in a new tab and click it again to view it 100% – each picture is 768 px h x several thousands w px
Above, a 50 picture stitched panorama: click it to open in a new tab and click it again to see it at 100%. This huge view spans from the Kleiner Myhten peak in caton Schwyz (left, 1811 m.s.l.) to mount Pilatus behind Lucerne (right, 2,128 m.s.l.). The mountains of at least 5 cantons are visible: can you spot the antenna on the Titlis peak?
Above, a 21 picture stitched panorama shot with the Nikon 70-200 mm pointing south at the Alpine border between Canton Graubünden and Italy
Above, a 12 picture stitched panorama shot direction lake Lucerne
Finally, a 6 picture stitched panorama shot with the Nikon 50 mm from Rigi Kulm towards Rigi Scheidegg.
With less than 16GB memory, merging a panorama made out of more than 10 pictures can be a problem with Hugin. Especially with pictures of 36 MP resolution like with Nikon D800. A solution comes from downsizing the pictures either to a) 5000 x 3333 px, for panorama stitches made out of max 20 pictures or b) 1600 x 1067 px, for panoramas up to 50 pictures. Here above you have panoramic views from Mount Rigi, “The Queen of mountains”, a 1,798 meter high peak in Switzerland.
Spring photo project, March 2015: floral landscapes
This is a research on creating landscape photography on plant subjects. Spring is blooming and high is the temptation of shooting single, static, wonderful objects like flowers and buds. However, where is the photographer interpretation in reproducing single objects? The creation of floral landscapes pushes the photographer to look for shape repetition, pattern development, light focusing, background uniformity, series building and contrast search. Below the results.
