Pelican Head Turbulence (John Hayes)

Pelican Head Turbulence

The skies over central Oregon have been absolutely spectacular lately with severe clear and unheard of seeing. Cygnus is my favorite summertime constellation with lots of interesting objects to image. After working on another really tough NB image for a few weeks, I turned the scope over to the Pelican Nebula (IC 5070) and wow, there is a lot going on in and around the head. You'll have to flip this image upside-down to easily pick out the Pelican but I prefer this orientation with the "sky-blue" O3 regions at the top of the frame. It's been a while since I processed a NB image so I had to take a couple of runs at it to get it where I wanted it. There is a lot going on in this area and some of the features are really fascinating. I'd sure love to have a go at this area with an even bigger scope!

The main features in this image are the knots and pillars of IC 5067 that make up the dust wall just "above" the Pelican. If you look closely right near the tip of the filament-like pillar near the center of the frame, you can clearly see the Herbig-Haro (HH) Object 555, which are two jets ejected from a hidden photo-star forming within the interstellar gas. These jets are being ejected at a speed of several hundred km/sec. This is one of the clearest examples of an HH object that can be easily imaged with amateur telescopes. At only about 1,800 lyrs, these gas clouds are pretty close by in terms of galactic standards .

Soon, I'll be moving my scope down to New Mexico and I'm looking forward to having more access to southern objects and winter skies. Hopefully we'll have it set up and running in the new location by the next new moon cycle but that will depend a bit on the weather. So, this may be my last image from Oregon (but we'll see.) As always, C&C is welcome so let me know what you think.

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.
