Northern hemisphere astronomy enthusiast and Islay Single Malt lover. Cats shall one day rule the world. 馃敪馃 馃悎 https://www.astrobin.com/users/Ltno/ Alumnus Universit茅 C么te d'Azur/OCA 馃敪馃寣 So long and thanks for all the fish...

Satellite trails shown over 8 hours of luminance exposures spread over three nights while trying to capture the galaxy NGC2655.
Astrophotography of the dark nebula LDN1251, the rotten fish nebula, shot with a Newtonian scope and a monochrome astrophotography camera using LRGB filters.
Astrophotography of the area around the Wolf-Rayet star W134, showing the outer oxygen-rich outer shell being blown away by stellar winds from the star. Image shot over several nights using a Newtonian scope and a monochrome astrophotography camera with narrow band and broad band filters.
Astrophotography of SH-114, the Flying Dragon Nebula shot using a monochrome cooled astrophotography camera and a Newtonian telescope with a diameter if 200mm. The total integration time is 9h. The image shows a large HII region that ressembles a dragon spreading its wings, flying though countless stars from the Milky Way plane.
The Hickson Compat Galaxy group n掳 68 (HCG68) shot over 5 nights using a 200mm Newtonian scope with a focal ratio of f/3.8 and a Player One Poseidon-M monochrome camera. The field shows HCG68 as well as numerous fainter, more distant galaxies and a few prominent neighbors.
An image of the galaxy NGC3718 and its neighbor NGC3729 with around 33 hours of integration time in various Scopes (Schmidt-Cassegrain and Newton) using color or monochrome cameras. The image shows details of fainter background galaxies.
Astrophotography around Keenan's system (NGC5218 and NGC 5216), with annotated Quasars, their redshift and their distance using a FlatLambdaCDM model.
Astrophotography of Keenan's system featuring the galaxies NGC5216 and NGC5218 sharing matter and tidal streams. This image is the result of the integration of 36 hours of data collected through 4 different setups, using monochrome and OSC cameras.
The Galaxy M63 shot using the combination of images shot with two same scopes (Skywatcher Quattro 200P) but different cameras (a color ASI294MC, and monochrome Poseidon-M). 15h of integration time showing lots of small galaxies in the background.
M51 Galaxy
IC434 the Horse Head nebula shot in L-Ha-RGB using a Skywatcher 200mm Quattro Newtonian and a monochrome PlayerOne Poseidon camera. The brighter stars show diffraction spikes typical of a Newtonian scope.
The Sun shot in H-alpha using a monochrome Zwo ASI1600GT camera and a Lunt 60 THa solar scope. This is the combination of two overlapped images: one overexposed to show the prominences and the other one to show the chromosphere details. False colors were used to render each of those overlapping images.
M82 galaxy showing H-alpha jets being expelled from its nucleus. This is a detail from a wider field of view given in this post : https://bsky.app/profile/ltno2.bsky.social/post/3m6ajatkmzs2e

M33 the triangulum galaxy. This image combine images from three different amateur astronomers for a total of approximately 17 hours of integration time. Details are on Astrobin : https://www.astrobin.com/ibi2sb/
The Sun in H-alpha in a black and white image, showing prominences and the chromosphere.
