Rho Ophiuchi

A mosaic of 2 images taken at Gila Cliff National Monument.

Dual Camera Setup

2 x 300mm f2.8 x Canon 6D

Mach1GTO (unguided)

Each panel is 2 x 20 x 180s at f4.5 and ISO 800

The processing was a challenge because the sensors had gotten extremely dirty by this time from being in the desert after some windy nights. There are still some artifacts in the images.

Oh yeah, the signs warning about mountain lions, bears, and wolves made it interesting also. Surprisingly for New Mexico in April, the temperature dropped down below 0C. Luckily, I had a bear kigurumi costume in the truck from Halloween. So I wore that when it got really cold.

While this is definitely not the best image of this object, the factors above make it a particularly memorable imaging session.

Note: This is fairly close to Plate 13 in E Barnard's A Photographic Atlas of Selected Regions of the Milky Way (except in color).

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.
