From the Cosmic Bat to the Dark Wolf

I have been individually imaged a number of these targets over the past past few weeks, but I wanted to put them all together in one panoramic shot. It turns out that unplanned mosaic ends up being quite wasteful in overlaps, with lots of panels oriented differently and lots of annoying little gaps to fill.

So the resulting image (bin x 2 so its easier to display) was observed in the most efficient manner, with over 20 panes each comprising 40 x 300 sec exposures at least. On average, each pixel was covered by 1.4 panes, so the resulting image is quite deep.

To give a sense of scale and an sense of fun, I also include a composite of part this image superposed on the sky as it would look at 7pm tonight. The head of the Scorpion makes for a magnificent site it is rises over the mountains behind my observatory (Mt Difficulty in the background and Nevis Bluff in the foreground), with the rig used to capture the image out in front of the observatory.

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.
