Our sky diary for May is now on our website: www.astronomyedinburgh.org/2026/04/27/s... 🔭

We have a talk this Friday May 1st at 7.30pm open to all on YouTube. Prof Ian Robson will discuss the discoveries that have led to our current knowledge of the Universe and examine the onset of ‘Big Data’ in modern astronomy. #astronomy www.youtube.com/watch?v=Y6wh...

A 3rd clear night in #Edinburgh! Seeing poor, but taking pictures of my favourite areas on the Moon - Plato and Hadley Rille. #CFF160 🔭, #TeleVue 2.5x powermate, #Touptek 585 mono camera. #astrophotography

A quick session in #Edinburgh before the Haar (advection fog) rolled in. Apennines with part of Hadley Rille, and Triesnecker and Hyginus Rille. #CFF160 🔭, #TeleVue 2.5x powermate, #Touptek 585 mono camera. #astrophotography

Two more Moon images from last night. #CFF160 🔭, #TeleVue 2.5x powermate, #Touptek 585M camera. Best 25% frames from 1000 frame video, stacked and sharpened in AstroSurface. #astrophotography

A couple of images quickly processed tonight. More to come tomorro. #CFF160 🔭, #TeleVue 2.5x Powermate, #ASI585MC for Jupiter, #Touptek 585M for the Moon/Sea of Tranquillity. Craters Armstrong, Aldrin, Collins are visible. #astrophotography

Two further images from tonight: (1) craters named after Armstrong and Collins near the Apollo 11 landing site, and (2) Jupiter and Europa. #CFF160 🔭, #TeleVue 2.5x Powermate, 585M camera for the Moon and 585C for Jupiter. #astrophotography

Daytime pictures of the Moon though an IRpass filter. #CFF160 🔭, #Televue 2.5x Powermate for the zoomed in image, #Touptek ATR2600M for the full disk image, ATR585M for the zoomed in image. Details of images in ALT text. #astrophotography

A short session last night to try out my new #Touptek #StellaVita. This is only 1 hour - 30 minutes L, and 10 minutes each R, G, B. Definitely more data needed, but a promising start. #TeleVue NP101 🔭, #Touptek 585M camera plus filter wheel, #ZWO AM5N. Processed in #PixInsight. #astrophotography

I took my 7 video derotated Jupiter image and inserted it into a single image showing Europa (L) and Io (R) in Gimp. The disk images were identical in size so it was simply a case of aligning the 7 video stack over the single disk with opacity set to ~30% and then upping the opacity to 100%.

I stacked 7 x 60s videos of Jupiter from yesterday (13 April) using #PlanetStackerX and derotated and sharpened with #LuckyStackWorker. The videos were taken with a #CFF160 refractor 🔭 (focal length 1050mm), a #TeleVue 2.5x powermate, and a #ZWO585C camera. #astrophotography

Probably one of the last Jupiter images from me this opposition as Jupiter sets earlier and it gets dark later. This is the best 25% frames from a single 60s video, stacked and sharpened in AstroSurface. #CFF160 🔭, #TeleVue 2.5x powermate, #ZWO ASI 585C camera. #astrophotography

My book's out on Thurs. I have a request - pls ask your local library to get a copy so everybody can enjoy it? (also available as audiobook). ISBN: 9781529930276 / @hjm.bsky.social @astroroyalscot.bsky.social @rogerhighfield.bsky.social @romatheengineer.bsky.social @robinince.bsky.social

Two great reasons to be a part of this Society - the Smart Scope Project encourages you to gather data and create your own image; and add it to the mix to create a collaborative image! We’ve got some excellent results! 😀❤️🔭

#Seestar S50 🔭 collaboration. 39 hours of M101 data gathered this year and last year. Individual stacked subs combined weighted according to total exposure time. This image processed by @mikechristie.bsky.social. #astrophotography

Short period of clear skies in Edinburgh just after sunset allowed me to get 3 pictures of the crescent Moon. #CFF160 🔭, #TeleVue 2.5x Powermate for the two close ups, and #Touptek 585M camera. Best 25% frames from 1500 frame videos, stacked and sharpened. #astrophotography

Also took 6 x 60s videos of Jupiter, derotated with WinJupos. #CFF 160 🔭, #Televue 2.5x powermate, #ZWO ASI585MC camera. Best 25% stacked in AstroSurface, then de-rotated, then sharpened. #astrophotography

A couple of Moon images from Edinburgh tonight. #CFF160 🔭 and #Touptek 585 mono camera. The zoomed in image used a #Televue 2.5x powermate as well. #astrophotography

Not the best seeing - in fact some videos were like looking over a bonfire - but you take what you can get! 13 x 60s videos, best 25% stacked, derotated in WinJupos, then sharpened in AstroSurface. #CFF160 🔭, #TeleVue 2.5x powermate, #ZWO 585MC camera. #astrophotography

First outing with the solar scope for about 6 months. Trying to remember how to get good focus in bright sunlight, adjust the etalons, and process the resulting image! Coronado #solar 🔭, Touptek 585M, best 25% frames from 2500 frame video. #heliophysics, #astrophotography

We have a talk on “Binary Stars and Stellar Cannibalism” this Friday 20 March at 7.30pm. Everyone welcome to watch: www.youtube.com/live/y49RT-T... 🔭

Headline: astronomy equipment is expensive! @iayc.bsky.social 2026 is in Spain with Bortle 2 skies and a total solar eclipse 🌚🌝 Due to the crazy increase in the cost of running camp and some poorly timed equipment failures, we are fundraising to update our equipment before the IAYC in July 🧵

An annotated version of the M81 & M82 collaborative image showing numerous faint galaxies. The faintest I've found in this image is PGC2730409 at magnitude 17.8. #Seestar 🔭 #astrophotography

We've just published a report on the power of collaborative imaging with multiple Seestars 🔭. 5 or 6 people (or more!) imaging the same target, and submitting their stacked images for further processing. #astrophotography #Seestar www.astronomyedinburgh.org/2026/03/15/m...

I've read and enjoyed a couple of chapters so far. Definite thumbs up and recommendation from me!

These two #aurora photos were taken 1 minute apart, showing how rapidly the aurora was changing. Taken on 24 February on a Fred Olsen Northern Lights cruise with the @gostargazing.bsky.social team. Taken passing Nordarnøya heading north from Molde in Norway 🔭

A collaborative effort imaging M81 and M82 with six Seestar S50 🔭 by @astronomyedinburgh.bsky.social members. 5.3 hours combined LP filter and 15.6 hours IRCUT filter. LP and IRCUT stacked separately, and stacked images processed in PixInsight. #astrophotography

The Aurora on my recent cruise to Norway was truly magical. I took these photos with my iPhone 15 Pro. 24th February 2026 sailing towards Narvik, Norway

Set the #Seestar S50 🔭 up last night and left it running while attending the @astronomyedinburgh.bsky.social lecture on the 72" reflector at Birr Castle in Ireland. This is two hours on M81 and M82 in mosaic mode, stacked on the Seestar and post processed in PixInsight. #astrophotography

We have a talk tonight by Bill Barton, Deputy Director of the Historical Section of the British Astronomical Association. We will also have the Sky in March. Free to watch on YouTube 🔭 youtu.be/vcGXZ0_Zcek

I’d been shooting the #aurora in RAW mode on the iPhone, and found I hadn’t processed this image. Hand held shot, 3s exposure. I liked the reflections in the sea. Taken on a Northern Lights cruise with the @gostargazing.bsky.social team on board. #astrophotography #heliophysics

Processed some more #aurora pictures from last night (24 Feb). All are handheld, 3s exposures on an iPhone in RAW mode. Taken on board a Northern Lights cruise with Fred Olsen and the @gostargazing.bsky.social team. #astronomy #heliophysics

Another #aurora picture from a Northern Lights Cruise with Fred Olsen and the @gostargazing.bsky.social team. At sea heading from Molde to Narvik. Several green arcs, some lights ashore, and the stars of Ursa Major above. Handheld iPhone, 3s exposure. #astronomy #heliophysics

#Aurora from #FredOlsen cruise ship north of Molde with @gostargazing.bsky.social #astronomy

Reminder of tonight’s online talk at 7.30pm on YouTube. Free to watch. 🔭
