Dolphin Head Nebula in HOO

Although I definitely need more hours on this target, I was pleasantly surprised how well the Dolphin Head showed up with less than 5-1/2 hours of total integration time. All subs were 5 minutes in length and I ended up using 45 OIII frames and only 20 in Ha. Shot with a Canon 500 f4 camera lens and a ZWO ASI 294mm Pro. The logistics for this target are difficult for me from my backyard. The Dolphin Head does not rise very high and is completely blocked by neighboring houses and trees from my location. The only way I can shoot it is to drive a short distance to a local beach and shoot out over the ocean's southern skies. Once I set up my imaging run, I curl up in the back of my undersized SUV and try to get some sleep. I never realized that taking up astrophotography as a hobby would require an investment in a good chiropractor!

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.
