Iris Nebula in Widefield

Two hours and eight minutes of integration out at a Bortle 4 dark site outside Scottsdale Arizona (Sears Kay Ruins), shooting from a Rokinon 135mm lens at f/2.5. Amazing what fast optics and dark skies can do. This region doesn't have any emission nebulae -- just a bright star inside this dust cloud illuminating it. It's amazing how dusty some regions of space are -- not at all open black but lots of dark material up there reflecting and blocking light sources.

My favorite thing is the tiny galaxy that snuck into the shot. In this little speck of 50 some pixels, every star some life-bearing planet there could ever hope to understand, make constellations from, and in the best chances, travel to, all just pinched down to a tiny spiral in a hobby picture. Crazy to imagine what is going on in there - someone looking back at us?

Samyang 135 f/2

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.
