The Pearl Cluster from Sydney

The Pearl Cluster from Sydney

The Pearl Cluster (NGC 3766, Caldwell 97), in Centaurus, from my backyard, 15 km North from Sydney’s city center, on 4th June 2020.

This image compiles 30 x 180s images (1.5 hours total integration time) obtained with my Skywatcher Black Diamond 80, an Orion X0.8 focal reducer (f/6), the ZWO ASI178MC camera and an OPTOLONG L-Pro filter.

I used the ZWO ASIAir to control the camera, the mount (Skywatcher AZ-EQ6) and the guiding system (ASI120MM + Orion 50mm finderscope).

Flats and darks included. Data processed with Siril software. Color / saturation / levels / contrast / smart sharpen with Photoshop.

Astrophotos and Seasons in Macquarie University’s “The Lighthouse”

Yes, I know this is another auto-publicity post, but that is also a way for me to keep track of all my appearances in media / news.

Today I’m very happy to share that my images and my… comments about the real (astronomical) beginning of the seasons  have appeared in this article of Macquarie University’s online newsletter “The Lighthouse”.

The Lighthouse” is the online Macquarie University‘s Newsletter that aims to  showcase of world-changing research news, expert comment and data-backed opinion. 

I want to thank Virginia Tressider for preparing this beautiful article in a very short time. I hope that many of these articles will come in the nearby feature.

My astro photos in ABC Breakfast News

Following the citizen science project aiming to raise consciousness of the increasing problem of the light pollution, as well as performing the Guinness World Records ™ Official Attempt for “Most users to take an online environmental sustainability lesson in 24 hours”, meteorologist, science communicator and TV presenter Nate Byrne has shared this morning some of my astronomical images in the ABC Breakfast Show.

 Nate Byrne talking about my astronomical images in today’s ABC Breakfast News. You can see the high-resolution image Nate is showing on my webpage and on my Flickr.

I’m extremely excited about all of this, and I really want to thank Nate for showing my images.

Unfortunately, though, I couldn’t watch the show, and it is not available on iView. I’m trying to get the screenshots of the other images that Nate shared today to include them here.

The Skyentists 038 – Always was, always will be

Today Kirsten and me have released the Episode 38 of our science communication podcast “The Skyentists”. You can listen it here:

or use your favourite podcast platform (check links here).

The details of this episode are:

In today’s episode of The Skyentists, astronomers Kirsten Banks and Ángel López-Sánchez talk about Australian Aboriginal Astronomy. Kirsten provides a general overview of the importance that Astronomy has always had on Earth’s longest-living culture: Australian Aboriginal people. In particular, she discusses how Aboriginal Australians draw constellations in the sky: connecting stars (as usually done in Western civilisations), using just single, bright stars like Arcturus, but also considering the “dark areas” of the Milky Way for creating “dark constellations”, such as the “Emu in the Sky”. Precisely the long, dark, Australian Aboriginal constellation “Emu in the Sky” (that crosses from the Coal Sack dark nebula in the Southern Cross to the Galactic Center in Sagittarius) is our “What’s Up!” for this episode. For Space News, Ángel talks again about the problem of the light pollution, this time not only from the perspective of Astronomy, but also environmental, our health, the impact in flora and fauna, and its useless waste of energy (=money). For this, The Skyentists invite everybody to participate in the citizen science project lead by The Australasian Dark Sky Alliance aiming to measure the light pollution of our cities and towns this Sunday, 21st June 2020. Kirsten brings a very interesting new result combining two independent works about Titan in Saturn. They also answer some questions and provide some extra feedback about the previous episode. More in two weeks!
