The Iris Nebula

I've mostly stuck to brighter objects before this, so this was my first attempt at capturing that really faint dust. Unfortunately, I had to throw out almost two hours of data, most of it since I didn't want to wait for the scope to cool down before starting to take images. But, so far I'm happy with this result. This nebula has a special meaning to me, as it was on of the cover of a book filled with Hubble images, and that started my fascination with space.

The Iris Nebula (NGC 7023/Cadwell4) is a reflection nebula located in the constellation Cepheus. The Nebula is illuminated by a magnitude +7.4 star which is designated as HD 200775.

Description: I recently acquired a new tool, specifically NoiseXTerminator, and I am stunned at how well this program has worked. I look forward to using it in the future.

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.
