Revision title: SH2-308, The Dolphin Nebula HOO (work in process - revised)

I’ve always been fascinated by photos oft he Dolphin Nebula and I finally managed to start my own attempt at imaging this target. I emphasize the word start as this target requires much more imaging time to improve the SNR for both the Ha and Oiii signal. In addition, the long-term plan is to add stars back in as RGB.

Due to my location, I only have a 2-hour window for imaging this target so it’s a long-term endeavor. I am excited by the data collected thus far. The Oiii signal was surprisingly strong. imaging this channel close to the new moon no doubt helped. I look forward to putting more time on this target.

I might switch my reducer/flattener out for the straight flattener when I get around to shooting RGB for the stars. I'm really disappointed with the star shapes out towards the corners of the image with the reducer. The straight flattener seems to be less problematic but given the money pit nature of this hobby I'm sure I can solve the problem with a high dollar Petzval scope!

Description: Still waiting for a new moon and clouds to move out so I can put more photons on this target. In the meantime, I tweaked the limited data I have to try and resolve some more details.

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.
