🔭 Webb's Rho Ophiuchi

A mere 390 light-years away, Sun-like stars and future planetary systems are forming in the Rho Ophiuchi molecular cloud complex, the closest star-forming region to our fair planet. The James Webb Space Telescope's NIRCam peered into the nearby natal chaos to capture this infrared image at an inspiring scale. The frame spans less than a light-year across the Rho Ophiuchi region and contains about 50 young stars. Brighter stars clearly show Webb's characteristic pattern of diffraction spikes. Huge jets of shocked molecular hydrogen blasting from newborn stars are red in the image, with the large, yellowish dusty cavity carved out by the energetic young star near its centre. Near some stars in the stunning image are shadows cast by their protoplanetary disks. The spectacular cosmic snapshot was released in 2023 to celebrate the successful first year of Webb's exploration of the Universe.

For #FossilFriday, a special look at a historic dinosaur trackway at Maya Dude Ranch near Bandera, Texas. Originally interpreted by Roland Bird in 1940 as that of a "swimming sauropod," discovery of more tracks by "Jurassic Judy" (Neuman) confirmed it as a walking (not swimming!) trackway. 🧪🦕🐾

Another comet Lemmon image, taken on 21 Oct.

For this one I used my mono camera with red, green and blue filters to capture colour data, which I added to the main mono image to create an LRGB colour image.

Scope was a 550mm focal length Esprit 100.

Comet C/2025 A6 (Lemmon) on the evening of 23 October. I was battling passing high level cloud, the neighbour's security light and time - the comet was setting behind a rooftop! Quite pleased with the result though, especially the structure in the tail. #Astronomy #Astrophotography #A6Lemmon
Image of comet C/2025 A6 (Lemmon) taken on 23 October 2025 at 19:04 UT. The comet is a green diffuse object in the centre of the image, with a structured tail sweeping up and away from the head of the comet. Stars are around it and seen as small trails due to the stacking process. Equipment and settings: Canon 250D DSLR through an Evostar 72ED telescope on a Star Adventurer mount. 21 stacked images at 10s exp, 420mm fl, f/5.8, ISO-1600. Using binoculars, I estimated the comet to be about magnitude 4.3, with a 3 degree tail.

Messier 14 is a moderately concentrated globular cluster located in the constellation Ophiuchus, approximately 30,300 ly from Earth. The cluster spans about 100 light-years in diameter and has an estimated age of 13.25 million years. #astrophotography @kat-astro-bot.bsky.social
Messier 14 – Metal-Poor Globular Cluster in Ophiuchus Messier 14 (NGC 6402) is a moderately concentrated globular cluster located in the constellation Ophiuchus, approximately 30,300 light-years from Earth. With an estimated age of ~13.25 billion years, it is a representative example of the old, metal-poor stellar populations that inhabit the Galactic halo. The cluster spans about 100 light-years in diameter and contains several hundred thousand Population II stars. Its low metallicity ([Fe/H] ≈ –1.28) reflects a formation epoch early in the history of the Milky Way. M14 is classified as a Shapley-Sawyer Class VIII cluster and exhibits a relatively diffuse outer halo surrounding a dense core. More than 70 RR Lyrae variable stars have been identified within the cluster, making it useful for refining distance measurements through the period-luminosity relation. In 1938, a nova event was recorded on photographic plates, one of the few confirmed nova eruptions within a globular cluster. Imaging Details: Telescope: Celestron EdgeHD 8" Camera: ZWO ASI1600MM Pro Filters: ZWO Red, Green, Blue (36mm) Exposure: Red: 96 × 60 sec Green: 90 × 60 sec Blue: 90 × 60 sec Mount: Sky-Watcher EQ6-R Pro Software: NINA (acquisition), PixInsight (processing) This image resolves the core and extended halo of M14 in broadband RGB. The cluster’s structure and variable population contribute to studies of globular cluster dynamics, distance calibration, and the early chemical evolution of the Milky Way.

It was travelling past the Sun at 430,000 mph (i.e London to New York in 30sec) at a distance of only 9.85 Sun-Radii above the solar surface. Temperatures were > 1000℃ 🥵

This is NGC6752, one of the brightest and nearest globular clusters to us at 13,000ly away. Working on RCW58 that sets at 11:30pm local, so I hopped over to this nice cluster for the second half of the night and got about 4.5 hours on it. #astrophotography

NGC 6752 – Globular Cluster in Pavo One of the brightest and nearest globular clusters in our galaxy, NGC 6752 lies roughly 13,000 light-years away in the constellation Pavo. This dense sphere of ancient stars is estimated to be over 11 billion years old and contains multiple stellar populations, including blue stragglers and millisecond pulsars—signposts of complex internal dynamics and stellar evolution. Captured using RGB filters, this image reveals the dense core and surrounding halo of stars, tightly packed into a cluster only ~100 light-years across. NGC 6752 is a post-core-collapse cluster, and its high central concentration is evident even at modest image scale.
