Conjunctions in August 2014 (part 1/2)

As winter sets in, I remember fondly the beautiful and mild summer that has just passed, with its breathtaking sunsets and nice weather... And sometimes conjunctions in the evening sky. :)

Speaking of, here are some photographs I took on August 29th, illustrating the conjunction between the crescent Moon and Spica (the alpha star in the Virgo constellation). All pictures were taken in Bucharest, at dusk.

Orion, the Hunter

The constellation of Orion is one of the most beautiful in the entire sky; and one that is easily recognized, too. Although from the southern hemisphere, the Hunter is upside down and that's a bit weird to see.

The brightest stars are:
  • Betelgeuse (on the right shoulder), meaning "the hand of Orion" (Arabic) - is a supergiant red star. So massive in fact, that if this star were at the center of the Solar System, it would extend beyond the orbit of Jupiter. But at its current distance of 640 light years away, it's the ninth brightest star in the sky.
  • Rigel (on the left foot) - is actually a triple star system, all of them shining in the blue-white spectrum. Rigel is the seventh brightest star in the sky.
  • Bellatrix (left shoulder) and Saiph (right foot) complete the Hunter's body
  • Alnitak, Alnilam and Mintaka create the asterism known as the "Orion's belt" - south of it is the sword - The Orion Nebula (M42). But M42 is the subject of another post.
For now, here is the Hunter rising above Valea Frumoasei, in the early hours of the morning of August 26th, 2014.

M42

M42 - The Orion Nebula

M42 and Orion's belt - a 2 min exposure at 200 mm

















The picture below was obtained by stacking 5 exposures, each 2 minutes,
4 dark frames and 10 bias. I used a Canon 450D with a 75-300 mm lens, at 200 mm, f/5 and ISO1600.
After stacking the image with DeepSkyStacker, I used PixInsight for post-processing - my first try ever.

I might mave exaggerated a bit with the Curves Transformation tool :)

a brief stay with the Kiwis

Back in the autumn of 2012, I took a trip to Australia and New Zealand. Several months have passed since then (more than several, actually :) ), but while flipping through some of the many photos I took on that occasion, I felt the need to write about the things I've seen and experienced.

First, here's a map of this short tour, with the few places I've visited on the North Island:






Nau mai! Haere mai! (Welcome to Aotearoa)










































Stay tuned, part one will follow in just a few days, as soon as I've finished selecting and giving some finishing touches to my photos.
