  1. While walking to the Good Food and Wine Festival down at #PCEC we saw this absolutely charming trompe-l'œil on William St.

    It continues down the road to the corner of St. George's Tce.

  2. Over the last three nights - a break in the weather for us here in #Boorloo ( #PerthWA ) - I've been targeting the same target after midnight and through to astronomical twilight. It is another target that is familiar to me - #C63 or #HelixNebula sometimes known as the Eye of Sauron Nebula or the Eye of God Nebula.

    This is the largest planetary nebula visible to us, only about 200 parsecs away, and is about 2.8 light years across, making it about 22 arcminutes across for the main body, and is about 6500 years old.

    So back to the making of this image. Each night I got about five hours of shooting in with my #Dwarf3 , for about fifteen hours total. I had to ditch a bunch of frames as they had dodgy data (atmospheric distortions, musktrails, and, in one case, a passing jet), which brought me down to thirteen hours and thirty-six minutes (816x60s@80). These I restacked using the "Megastack" function of the #DwarfLab app (about 3 hours - executed entirely within the telescope), and then passed the result to the #StellarStudio part of the app (running in the cloud) to optimize the FITS file and run a star removal.

    I then exported a PNG of each version, and started post-processing. This consisted of passing the starless image into #Snapseed and boosting the saturation, darkening shadows and so on. Then I took the optimized version and took the shadows to maximum darkness, and reduced the overall brightness somewhat, leaving me with a reduced star version, with almost no nebula visible. Lastly, in Snapseed again, I used the double exposure tool to stack the two parts together.

    And here is the result.

  7. Since October last year, I have had a set of solargraphy cameras set up at Rooftop Movies.

    Their season, and mine, have now wrapped, so here's the writeup and the photos!

  10. So Astrofest is done and dusted for another year. For the first time since the early 2000s (when we did model rocket displays) we were volunteers. This time we were running one of the telescope pods - the Smart Telescope pod, which, unlike the other pods, was not limited to a single target. We were all over the sky, making the most of the ease of control and versatility of these fun devices.

    @leece and I had three DwarfIIs, there was a pair of Seestar S50s, a Unistellar EVScopeII, and even a Vaonis Vespera II (which is a work of art, as well as being a stunning telescope).

    We even had someone doing it oldschool with a guide mount and a DSLR with a very beefy lens!

    We started the afternoon with sun and moon viewing - made challenging with the sunlight on our screens. After, one of the S50s continued with the moon for the rest of the night, while the rest of us went on to other targets, including 47 Tucanae, the Cat's Paw Nebula, C65 (The Sculptor Galaxy), The Lagoon Nebula, the SMC, the LMC, and even a random star that someone had the coordinates for tattooed on their arm!

    We were on our feet pretty much from 2:30 when we set up to 10:30 when we finally departed, and talked to the public almost non-stop from about 4pm. We answered questions about what these weird looking devices were, and why people were not looking through them, what they could do, how much they cost, and which were the best. This last one was a tough one, as we own one brand, and there was another brand in the same price bracket right next to us :) We were fair, though, and highlighted the pluses and minuses of each. And explaining, many times, that we were not selling them.

    Early in the evening Leece did duck off to watch the Astrophotography competition awards, as she had been shortlisted. And, to her surprise, she had just sat down when they announced the winner for the Night Sky Friendly Lighting category - with her image of the rising galactic core over a resort near Bindoon taking the prize!

    It was a fantastic, if exhausting experience, and one we look forward to repeating in Feb 2026.

  11. #PerthWA is my first stop on what is not a #RoundTheWorld trip or a #There-andBackAgain but a really big circle with doubling backs.
    Most of the places I'm visiting are stops planned with a purpose of visiting, but I'm starting with places that are transport links, Perth being between London and my first place/thing of intent in Australia.
