A star field surrounding a line of seven images of Barnard's Star, each of which were taken one year apart from 2019 to 2025. Those images demonstrate that Barnard's Star is moving remarkably quickly against the background sky.
8 globular clusters in M31. From top to bottom the marked globular clusters are B226D (Vmag 17.89), DA069 (~18), B243D (18.05), B238D (18.05), B235D (17.93), B245D (18.22), B356 (17.34) and B108D (18.80).
An over-exposed image of Sirius, the Dog Star. Near to it is the much fainter Sirius B, aka The Pup, which is the nearest white dwarf star to the solar system.
Full disk image of the sun in white light, showing a line of sun spot, two of them quite large.
Me standing in the Navigator, Little Shelford with an almost empty pint beer glass in one hand and a five-foot wooden staff in the other. I am wearing a pointy hat and a long gown because my facial hair is very similar to of Gandalf.
Albireo, aka beta Cygni, and its surrounds as seen in 40 second stack of images taken by a Seestar S50
Six images of Barnard's star showing how it moves against the background stars over the years 2019-2024.
Oh my god, it's full of stars! A dense star field which almost hides a globular cluster within it.
The Trans-Neptunian object (55565) 2002 AW197 appears as a faint dot in the centre of a star field.
Seven faint globular clusters located in the Triangulum galaxy, aka M33, are marked. They are labelled by their catalogue numbers M33-207, 2016, 2236 20663 20636, 2222 and 2298
Palomar 5, a faint and sparse globular cluster in Serpens. To bring out the faint stars, contrast stretching and noise reduction was applied with the FABADA package.
Comet 29P/Scwhassmann-Wachmann in a rich star field. The comet's coma is almost circular, there is no discernible tail and the nucleus is very bright.

Five overlaid images of Barnard's star showing its movement from 2019 to 2023.
Several lenticular clouds from El Pao, La Palma, in the Canary Islands. My house in the foreground,

Globular cluster Messier 5. The RV Tauri-type variable star is marked; it was near maximum on 2021-07-02 when this image was taken on a 0.4m Dilworth reflector. Exposure 35 seconds with a Starlight Xpress CCD camera.
Ash and steam cloud rising from the Tajogaite volcano 30 minutes after the start of the eruption on 2021-10-19. Tacande Observatory is in the foreground.
A nice pair of boobies. Latin name is Sula nebouxii

Two images of a star field. The one on the right is the raw data from the camera. The left is the result of smoothing by Fabada.
6 faint globular clusters are marked in an image of NGC 253, a galaxy 11.4 M light years away. The galaxy itself is greatly over-exposed.
