I have been an Astrobin member for some time now, always in awe of all the wonderful photos other members produce. This has inspired me to to take the plunge and this is my first post on Astrobin and my second attempt at this, my first deep sky photo. Taken from a Bortle 7/8 zone in Cape Town, South Africa. The ambient light pollution aggravated by a very nearby streetlamp caused gradients in my first attempt that I just could not get rid of. I therefore re-took the images the following night, a few hours earlier with Orion in a different part of the sky. This improved things and a combination of ABE and DBE in PI eventually made things manageable. There is a lot to learn. First for me is learning to calibrate my images. This image is uncalibrated and the lack of darks and flats made things very tricky. Looking forward to the journey...

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.
Dismissals 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.
