Quick crop of a quick stack - #Comet C/2025 R2 (SWAN) passing Antares below the Dark Horse nebula in the Milky Way - also visible - #asteroid #Vesta and other things. 10th Oct at Palm Beach, New South Wales. Canon 6D on Askar SQA55 on SA Pro mount. Two versions, second one has things labelled 🧪🔭

Comet C/2025 R2 (SWAN) is adjacent to the star Zubenelgenubi tonight. The brightest star in Libra, it has one of the best roll-off-the-tongue names.. 🧪🔭

For the closest approach between #comets #SWAN & #ATLAS on 20th Oct I went to a darkish site with everything but a power pack for the mount. Next night was problematic - windy, light leaks, I messed up the flats - hence this belated and grubby rendition - see Alt texts. 🧪🔭

Well the smoke pretty much cleared and I got the two comets 4.5 degrees apart in one picture, along with Mars. They are moving in different directions, so are blurred against the fixed stars. I can fix this but for now here's a quick star-aligned stacked image along with an annotated version 🧪🔭

The attempt to capture two comets in one image with a diminutive telescope has been successful two nights ago from an urban environment and last night from a relatively dark (if smoke-affected) site. Will take a while to process the images 🧪🔭

Hoping some of the 'controlled hazard reduction burn' smoke leaves before the comet shows up 🧪🔭

Here are 'close-ups' of the two #comets as they appear in relation to each other and #Mars on the evenings of 20th & 21st September. Spica is out of shot. Comet #SWAN is likely to be about 2 magnitudes brighter than comet #ATLAS, but comet magnitudes are a bit - unpredictable.. 🧪🔭

If you're more than 50 degrees north or south of the equator - and if it's dark, there could be some auroræ happening:
(Times are in UT, which is ~same as GMT, or BST minus 1 hour).

Spent an hour in a local park in #Sydney to image the 'new' #comet SWAN25B as it appeared just below Spica and Mars. Bit of a tail despite the seeing conditions (light pollution, haze, low elevation). Canon 6D Mk1 on Askar SQA55 on SA Pro mount. Not yet visible to naked eye (use binoculars)🧪 🔭

Two more images from pre-dawn on 26th April in #Sydney Australia - this time two telephoto pics of the #Moon. Note the difference between the two exposures - 1/2 second shows #Earthshine while 1/40 second shows detail in the smiley crescent 🔭🧪

A whole bunch of things arrived in the east before dawn yesterday - among them the 5.6% illuminated #Moon with #earthshine, just 4 degrees from the #planet #Mercury.
Here's the view from #Sydney - Sigma 18-300mm lens at 170mm on Canon 600D. 🔭🧪

Can you spot Proxima Centauri here - the closest #star to us after the sun?
It's the third star in the triple system #AlphaCentauri (See second image). It orbits the double star Alpha Centauri AB, and is currently 3.5% closer to Earth than the main binary Alpha Centauri AB. Details in Alt texts.🔭

On this day a year ago I was at the Unit for Arid Zones of the Chapingo Autonomous University near Torreón, #Mexico.
This was 3.8km from the #eclipse centreline and 85km along that line from the point of maximum. These are the first images I've posted from that total solar eclipse - big backlog 🔭🧪

The recent #Moon - #Pleiades #occultation was invisible from #Oz but here's one I saw in the #UK on 7th Aug 2007. I took some pics with a cheap compact camera and sent them to Rhod Sharp on the BBC's 'Up All Night' radio show - here's what he said - Need sound on 🙂🔭🧪

Three #planets were within about 8 degrees of each other this morning as seen from Dee Why, #Sydney #Australia this morning before dawn. Left to right, low over the Pacific Ocean - #Venus, #Mercury and #Saturn. Image lightened a little to show the dark ocean better on a phone screen 🔭🧪
