My research in Astrophysics is focused in the analysis of star formation phenomena in galaxies of the local Universe, especially in dwarf starbursts and spiral galaxies, but using a multiwavelength approach.

I want first to congratulate the GALAH team for the success of this impressive star survey conducted at the AAT with the amazing 2dF + HERMES instruments (they have compiled the spectra of almost a million stars in Milky Way ..read more

Text adapted from two lengthy posts that ChatGPT just generated for me after providing it with several posts from my original Spanish blog, giving it a brief list of what I am currently doing and how I feel, and asking it to write it for me. Then translated into English.
Here I am, in the control room of the Anglo-Australian Telescope, in the midst of the starry night. It’s 3 AM, and there are still three hours left until my observation session ends. The atmosphere in the room is calm and serene, filled with anticipation for what lies ahead.
My main goal for the night was to obtain observation ..read more

Today I have been interviewed in ABC radio about my research and my passion: astrophotography, as well as the increasing problem of light pollution. I want to thank Shelby Traynor for her time and for the interview.
Listen the interview (7 minutes) in the ABC webpage, “Could light pollution dim our passion for astronomy?”
This is part of my “Residency at Sydney Observatory”, that I was awarded in 2020 but, because of combinations of reasons, I couldn’t start till now. Stay tuned for more news about this ..read more

One of my favourites stories in my blog is “Seasons: Astronomy vs. Australia” that I published exactly 8 years ago, on the 1st September 2014. In this post I described how seasons are defined using Astronomy using equinoxes and solstices. And that I was very surprised to see that in Australia that is not what people think.
Indeed, you have probably heard me complaining for years about how Australia and New Zealand use the meteorological definition of season instead of using the astronomical definition, that is the one that is followed almost in the rest of the world.
Last week I raised the iss ..read more

The Milky Way rising over Siding Spring Observatory (NSW, Australia) while my amateur telescope observes under a dark sky. Single, 30s exposure, frame using a CANON 5D Mark III with 14mm lens at f2.8, ISO1600, taken the 22nd April 2021at 2:09am local time. Minimum process (curves, luminosity, contrast, saturation and noise reduction) with Photoshop Raw. This is part of a time-lapse I still have to process!

Deep H-alpha image of the Prawn nebula (IC 4628) in Scorpius obtained from my backyard, 15 km from Sydney’s city centre.
This image combines:
56 x 900s (14h) frames with the H-alpha Baader 3.5nm ultra-narrow filter (red channel and luminosity layer).
25 x 60s (25 min) frames with the OPTOLONG L-Pro filter (green channel)
14 x 30s (7 min) ZWO B filter (blue channel).
Total integration time: 14h 32 min.
The data were taken on the nights of 24th, 25th, 28th, 29th and 30th August and 7th and 12th September 2020.

Article originally written for the AAO’s Newsletter published on 29th June 2021.
During the last year I’ve been setting up my telescope in the backyard to do astrophotography as an amateur astronomer. This has been possible thanks to getting a good mount (Skywatcher AZ-EQ6-Pro) that allows me to do auto-guiding, and using a little but very clever device (it’s a modified Raspberri Pi manufactured by ZWO called “ASIAir”) that allows me to connect mount and cameras (the main camera for astrophotography and the auxiliary camera for auto-guiding) together, being everything controlled using my son’s ..read more

This image combines 50 x 1″ exposures, ISO 800, obtained with my CANON 5D Mark III attached at primary focus of my Skywatcher Black Diamond 80mm f600mm (F/7.5) during the Total Lunar Eclipse on Wednesday 26 May 2021, between 9:00pm and 9:04pm, Sydney local time.
The frames were manually aligned with Photoshop, then extracted as new frames to Lynkeos, that did the fine alignment. Drizzling x2 was also used. Then the combined image was taken to Photoshop, where the colour, highlights/shadows, and contrast were tuned. This got only the image of the eclipsed moon.
Additionally, I combined the ful ..read more
