Iris Nebula Widefield

Hello Astrobin friends!

This is a bit of an experiment - I have seen so many great pictures on here of the Iris nebula and its dark nebula surrounds I thought I would have a go from here in Leeds under Bortle 7 /8 skies

I caputured just over ten hours of data over two nights with the Redcat51 (30 second exposures)

The results were very very rough although I could see some of the dark nebula with extreme stretch there were horrible gradients and banding noise

I have done my best with the resuts and have merged in data taken from Spain at 520mm for the core

It gives a sense of what is going on in this region and given the terrible data I am pleased with the result

Pl do let me know what you think!

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.
