IC5070 - yet another 50 shades of grey study in Ha.

Even when it is forecast clear the elements conspire to make AP frustrating. A near full Moon, high veil cloud and poor 'seeing' all add to the challenge of getting any sort of image. Moan over.

This is just 12x300s of Ha using an Antlia 3nm Ha filter with an ASI183MM and a StellaMira 90ED. I actually took 17 frames in the limited period of nautical darkness but five had to be scrapped - the remaining twelve are what they are.

In the end, after some careful processing, the resulting image is quite revealing and well worth the effort of setting up.

Thank you for looking.

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.
