First noctilucent clouds I’ve seen this year. They’ve been more elusive than recent years. This was before dawn on 3rd July from south Oxfordshire, UK #astronomy #astrophotography 🔭

Venus and Mercury on 9th March from Oxfordshire, UK. I've been clouded out the last two evenings so this is the closest I'll be able to get them. The star top right is Algenib in Pegasus. A 6s exposure on an Omegon clockwork mount with a Cinesoft Subtle filter. #astrophotography #astronomy 🔭

My latest attempt at Jupiter from last night. Ganymede (top left) has just emerged from behind Jupiter and Io (bottom right) has just transited Jupiter and is casting its shadow. 300mm F/4 Newtonian with 2.5x PowerMate and ASI662 camera with contrast filter. #astronomy #astrophotography 🔭

The DWARF II smart telescope is a surprisingly capable little thing. Here is an image of M42 taken a couple of nights ago from my very light-polluted back garden. This is 100x15s exposures, stacked within the device and some post-processing in PixInsight. #astronomy #astrophotography 🔭

I've never been much of a planetary imager so I thought I'd try and improve! Jupiter this evening using a 127mm Maksutov-Cassegrain and a ZWO ASI662 camera. Best 5% of 5000 frames stacked in AutoStakkert and processed in PixInsight. Io (left) and Callisto visible too. #astrophotography #astronomy 🔭

Finally got a clear night to try my new ZWO ASI662 colour astro camera. This is a mosaic of 28 images using a 12" F/4 Newtonian telescope. Best 100 frames from 200 in each video stacked in Siril, stitched in Microsoft ICE, post-processed in PixInsight. #astronomy #astrophotography 🔭

Nicko McBrain is stepping back from touring with Iron Maiden. Tonight will be his final gig. It's been a privilege to see him with the band the past 36 years during which time I've seen them live around 25 times. I wish him all the best for the future. www.ironmaiden.com/an-announcem... #ironmaiden

Autumn is an ideal time to image the waning Moon as the ecliptic makes a steep angle with the horizon so it's high in the sky at a sensible time. This was taken last night with a DWARF II from Oxfordshire, UK. A stack of 50 x 1/500s images post-processed in PixInsight. #astronomy #astrophotography 🔭

No comet for me this evening, it went cloudy before it got dark enough and it's not visible on any of my speculative photographs before the clouds rolled in. It is now raining! Will try again tomorrow. #comet #tsuchinshan-ATLAS

Last night's aurora simmered all night but peaked after midnight. This video from my all-sky camera is from 00:00 to 02:00 BST in south Oxfordshire, UK at 51.6°N. The greens come out whitish on this camera #astronomy #astrophotography #aurora 🔭

I think we could all use some good news right now, so here you go: Bright comet Tsuchinshan-ATLAS will become visible in the evening sky starting tomorrow night. Clear view to the west essential. Sharp eyes highly recommended. Pointers at the link. skyandtelescope.org/press-releas... 🧪🔭
The bright Comet Tsuchinshan-ATLAS will first become visible in the evening sky on October 11th, appearing between Antares, the brightest star in the constellation Scorpius, and Arcturus, the brightest star in Boötes. While opening night will have it competing against twilight, it will be both higher in the sky and more visible against darker skies on subsequent evenings.

The DWARF II Smart Telescope is also a capable solar imager using the supplied filters. Took me just a few minutes to image today’s Sun. Stack of 50 x 1/400s exposures. Gain 0 and IR cut. A modicum of processing, cropped, rotated, sharpened and warmth adjusted 🔭 #astronomy #astrophotography #dwarfii
