Dolphin nebula sh2-308

I pointed my telescope to capture the Dolphin nebula Sh2-308. This nebula is located in Canis Major constellation. It's composed of ionized Hydrogen due to presence of high energetic central star called Wolf-Rayet star. This star is in a pre-supernova phase. It expelled its outer shell to form this nebula. Gear setup: Celestron RASA 8, iOptron GEM 45 guided by ZWO Mini guide scope & ZWO 120MM-S, ZWO 533MC @ -10, IDAS NBZ Nebula Booster 2” Filter. Lights subs 50 x 180sec, Darks 20, Flats 20, Bias 50, total exposure 2.5 hours. Captured by APT, PhD2, Stacked in APP, processed in PI & PS. Imaged from Bortle sky class 4.

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.
