Moin alle ✨

💫 Kennt ihr #Analemma? Nein nicht #Baerbock! Heute gehen alle #Sonnenuhren richtig, weil #Zeitgleichung=0. *
💫 größte Sonnenuhr: place de la Concorde. Die Guillotine wurde durch den Obelisk ersetzt. Heute zeigt sein Schatten die Zeit am Boden an. *
💫 wenn man einen Toten töter tötet, ist das dann Mord oder nur eine Korrektur? *

Kommt gut ins Weekend und seid nett zueinander

Sometimes experiments fail. I was busy shooting a year long analemma shoot from my bedroom window. After six months I bloody well knocked the tripod and lost the alignment. So here's six month's of an analemma shot at 4:15 each day (5:15 in summer) using a Mamiya Press Camera with ISO 50 120 film. Exposure was 1/500 second. #analemma #failure

Setting up my new 8x10 pinhole plate camera for my next analemma series. #analemma #analogue

Happy analemma crossover day! Today is one of the two days each year when the sun is in the same place in the sky at noon (and pretty much at any other time of the day!)

This gives me the excuse I need to post an annotated version of the analemma image I took between September 2021 and September 2022. Each day at 04:00 UTC , if the sun was shining, I took a 20 second exposure using a 4x5 inch pinhole camera. #analemma #astronomy #NewZealand

Happy autumn equinox everyone! Only six months until my next analemma picture is finished! Can't wait to see it.... #analemma #equinox

Number 1 in #IansTop102022 . This image took a year of my life to obtain. In September 2021 I loaded a pinhole camera with a 4 inch x 5 inch format glass plate with ISO 2 sensitivity. Every clear day, at 4pm in winter & 5pm in summer I took a 20 second exposure (manually) by opening the camera shutter. In September 2022, I stopped the exposure & developed the plate. Here's both the negative & the result. I bloody love this picture. It's a labour of love. Happy new year everyone! #Analemma

Also, looking for sunset/sunrise graphs, I have learnt that the position of the sun in the sky observed from the same position on earth at the same time along the year is called an #analemma.

It's December 21st, the winter solstice, and as fulfilment of my obligations as an astronomer under the Retrograde Mars Treaty of 1821, I must post a picture of an #analemma or the sun rising over a calendar circle to mark the #solstice.

Yes! My analemma image made the cover of the December issue of "Southern Stars" the journal of the Royal Astronomical Society of New Zealand. I'm ever so slightly stoked about this. #astronomy #analemma #NewZealand

About a week away from winter #solstice and we’ve entered the season of the #analemma:
Around about now the Northern hemisphere, evenings are starting to get lighter again!
Sadly the mornings keep getting darker until almost new year…. Still, the evenings are no longer drawing in! Celebrate and be merry!

There are a few “clubs” I’m so proud to be a member of. One is the Analemma club. https://analemma.pl #analemma

Happy Cross-Quarter day everyone. It has been 45 days since the Spring Equinox and we are just 45 days away from the summer solstice here in the southern hemisphere! Here's a picture of an analemma which I took which shows the motion of the sun in the sky over the course of a year if you photograph it at the same time each day. The figure 8 shape is caused by earth's tilt and the shape of our orbit. #analemma #crossquarterday
