Altair, Tarazed and Barnard 142 & 143 with 200mm Lens in APS-C

Altair is the twelfth brightest star in the night sky and the brightest of the constellation Aquila. Altair is eight times brighter than the Sun and is located at only 16 light years away. For astronomical standards, it is literally one of our neighbors in the Milky Way. A very newer neighbor, the star is about one billion years old, almost five times less than the sun.

Already Tarazed, the red star in the center, is actually a double star, despite being much brighter than Altair, it is located at a distance almost thirty times larger.

The two dark nebulae on the left part of the image are the objects Barnard 142 and Barnard 143. The two nebulae are also called E Nebula. If you pay attention you will see that they form the drawing of the letter "E" capital (backwards ).

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.
