I've had a go at imaging the Dumbbell Nebula (M27) using my #Seestar S50 smart telescope. This is just 50 minutes integration. I will add more data in due course. Processed with Siril, GraXpert, Starnet++ and Gimp. #astrophotography #PhotoHour #photography

I see Maggie Aderin-Pocock is giving the Christmas Lecture at the Royal Institution this year. Should be good. #astronomy

Had a couple of bets on the horses today, one at York and the other at Naas in Ireland. Won £68 altogether. Happy days. 😀 #sport #horseracing #betting 🏇

I shall reach the grand old age of 65 this coming Sunday. I’ve decided I need a new hobby so I’ve bought a #Yamaha #Pacifica #electricguitar 112v. Time to make some noise. 😀🎸 #musicsky #rockmusic #guitar

Those of you who own a #Seestar may like to know that there is a firmware update available to download. Details below.

I’ve been learning how to use Siril, GraXpert, Starnet++ and Gimp to process Astro images. I downloaded free Seestar data from Abdur Astro’s YouTube channel and this is my first attempt at processing the Orion Nebula (M42) using that data. 😊

www.space.com/astronomy/as... Interesting article on the DART results. #astronomy
NASA's asteroid-crash Earth defense tactic has a complication — DART ejected large boulders into space

It’s been a while since I last posted a photo on here. This is today’s Sun in white light. Taken with a 4 inch refractor and ZWO ASI 174MM camera. Software: SharpCap, Autostakkert, ICE, Registax and Gimp. Some nice spots on view. #astrophotography #StormHour #PhotoHour 📷

@emily.space I’ve noticed the astronomy and astrophotography feeds have not been working on my phone since yesterday lunchtime although everything else on here is working. Is there a problem with these feeds? Is this something you can check or should I get in touch with Bluesky support? Thanks.

I’ve received a couple of red alerts from my #aurora app. Not much use during the daytime but if it keeps this up then tonight could be interesting. #astronomy #sun

Last night’s Moon. A partially cloudy sky here last night so for quickness I used the #Seestar S50 smart telescope instead of my usual gear.

#astrophotography #PhotoHour #StormHour 📷
The Moon. Light grey in colour with darker grey patches representing the lunar seas. There are numerous craters across the surface.

Today’s Sun in white light. AR 4079 is a large active area on its way round, see here. Imaged using a 4” refractor and ZWO ASI 174MM camera. X3 barlow lens for the close-up. SharpCap/Autostakkert/ICE/Registax/Gimp. #astrophotography #StormHour #sunspots #sun 📷
The yellow disk of the sun showing a few dark sunspots. A close up of active region AR 4079. This region shows two dark areas called the umbra surrounded by a lighter coloured penumbra.

Just bought a useful addition to my solar imaging: a solar continuum filter which will boost contrast and cut atmospheric turbulence. All I need now is ☀️ #astrophotography
A thumb and forefinger holding a small, circular solar continuum filter. The filter has a highly reflective surface and a black rim.

A quick photo of tonight’s 95% Moon, taken with a #Seestar S50 smart telescope and with a little tinkering on my iPhone to create a mineral Moon. #astrophotography #Sciart #PhotoHour 📷 #Moon
A mineral Moon. The Moon here is almost at full phase. The colours are due to minerals in the lunar soil. A bright crater called Tycho can be seen at the bottom of the picture.

Some more lunar images taken last night. As before, the images were taken through a 4 inch refractor but this time I used a ZWO ASI 662 colour camera. Software : SharpCap, Autostakkert, Registax and Gimp. #astrophotography 📷 #PhotoHour
