Bonjour,

Il s’agit de plusieurs galaxies dont un amas (Abell 576)

Pris avec une Sbig ST2000XM sur un Maksutov (MC MTO-11), le tout sur une iOpton IEQ45.

Le MC MTO-11 est un très bon Objectif de construction Russe.

D'origine il est à 1000mm de Focale pour un Diamètre de 100mm. Ce qui en fait un F/D10.

Mais en retirant la lentille qui ce trouve a l’intérieur, il devient un ~F/D6.5 (~650mm de Focale).

Le seul problème,c'est la mise au point. En effet, j'ai dû scier une petite partie du

tube au niveau de la mise au point, pour pouvoir atteindre le point de focale avec n'importe quelle caméra.

Ce Maksutov ne subit aucun chromatisme ni coma.

Ceci dit, il subit de l'astigmatisme sur des cibles proches. Donc, je l'utilise qu'en astrophotographie.

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.
