LDN 1228 dark nebulosity - More data

This image is the result of having three times more data than in my previous post. It made such a difference that I post it separately. So now 6 hours in stead of two hours and even at f/2, faint objects like these "dark" nebulae need integration time. Much less frustrating to process and no NR had to be applied this time. Data collected over three nights 24 - 27 August.

Stacked in PI and processed in PS. No crop so the RASA 8 is quite good at filling up the ASP-C sized chip of the ASI2600. No flats or darks or any calibration done and not needed as far as I can tell.

LDN 1228 is a dark nebulosity site in Cepheus. Quite some amazing shapes formed by the dark dust - food for fantasy.

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.
