Comet 220P/McNaught experienced one more powerful outburst in early August, resulting to a growing conical shell with a central ridge, with extends for a degree in lenght as of 23 August (more info in alt). #cometWatch #astrophotography

Comet 220P/McNaught is featured in front of a starry field. The comet has a bright nucleus with a rather faint green coma about 6 arcminutes across and a slight curved dust tail with a central ridge extending to the edge of the frame.

Comet 10P/Tempel has a very prominent dust trail and it is a rare opportunity to photograph such a feature. Its ion tail is also visible, to the right and below the dust trail. At around mag 8.5, the comet can be observed with large binoculars, in Capricorn. #cometWatch #astrophotography

Comet 10P/Tempel features a large green asymmetric coma, about 18 arcminutes across. A faint line runs diagonally across the image and though the nucleus, representing the dust trail of the comet, created by accumulated dust from past apparitions. To the right of the nucleus and below the dust trail is visible a faint tail. The image follows the movement of the comet, with the stars appearing as trails.

Comet C/2025 A6 (Lemmon) is much brighter than current predictions (maybe around mag 13) and even visible in the individual 20s frames today before dawn. Hopefully it will be a nice binocular object in autumn. #cometwatch

Small comet C/2025 K1 (ATLAS) passing at the border of Hercules and Ophiuchus on 13-8-2025, 19:00 UTC. Coma about 0.5' and tail 5', doesn't appear to have grown larger the last half month despite the comet approaching both the Sun and Earth. #Cometwatch #astrophotography

A small comet with dusty tail passing through a starry field. Acquired with a GSO N203/800 telescope with TS GPU coma corrector. Unmodified Olympus E-PL5. 80x30s ISO 1600 light frames. Edited with DSS, SIRIL and GIMP.

The beautiful and historic cave of Melidoni in central Crete. A nice place to visit in a hot day. #crete #cave

Photo of the astroparty of the local astronomy club last weekend. Not many participants, but good food and clear skies. #night_sky #astrophotography #Crete

A group of amateur astronomers with theis telescopes (two neutonian telescopes in the foreground). The scene is illuminated by a red light. Milky Way is visible in the background. Single 20s exposure, f/4, ISO 2000, ultrawide view (16mm eq).

Small comet C/2025 K1 (ATLAS) at mag ~14 is the brightest comet in the sky right now. Tail is about 5' long. Currently in the constellation of Vulpecula, it approaches rapidly Earth next month. #cometwatch #astrophotography #comet

The small comet is moving quickly is respect with background stars. It features a narrow tail making it look like a pin. Equipment: GSO N203/800 telescope with TS GPU coma corrector. Unmodified Olympus E-PL5 camera. 100x30s light frames stacked in DSS and edited with SIRIL.

The Cocoon nebula (IC 5146) in Cygnus. Slightly over 4 hours of data with an unmodified camera from a B4.5 sky. Unfortunately the dust isn't well visible. #astrophotography #nebula #nightsky

The Cocoon Nebula appears as an almost circular pink bright area in the middle of a starry field. Some dark lanes are visible in it, as well as a central star.

Aquaired with a 8inch f/4 telescope with coma corrector. 368*40s light images. Edited with DSS, SIRIL and starnet ++
