Nébuleuse variable de Hind

Link to TIFF/FITS: https://flic.kr/p/2k1a6KV

Le même soir où j’ai imagé les Hyades, en regardant de plus près le Triangle du Taureau sur Stellarium, je m’aperçus qu’il y avait un peu au-dessus des Hyades la nébuleuse variable de Hind. On la voit sur l’image grand champ en haut à gauche comme deux étoiles entourées d’une voile de gaz. Je décidais alors de la viser avec la lunette.

Cataloguée NGC 1555, cette nébuleuse par réflexion est éclairée par l’étoile variable T Tauri qui est un système stellaire triple. Elle a été découverte par l’astronome John Russell Hind en 1852 et se situe à environ 600 années-lumière de nous.

Malheureusement, ma monture ayant un souci de connectique, elle a subi des microcoupures. Je n’ai cumulé que très peu de poses pour ce genre de nébuleuse. Cependant, l’image n’est pas trop moche et on voit la nébuleuse. Je la soumets donc à votre bienveillance.

Photos prises le 15 octobre 2020 à Allons (47) – Canon 7D défiltré partiel au foyer d’une lunette 100/900 Skywatcher sur monture Orion Sirius EQ-G (sans goto ni autoguidage).

33 poses de 2 minutes – ISO 6400 – 23 DOF – Iris et Toshop.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
