NGC 5907

This image of edge on galaxy NGC 5907 was a real challenge to process. For reasons I haven't yet figured out the sky flats I shot at twilight strongly over corrected the lights during calibration. I never had this problem before and I didn't make any changes to my work flow. After much trial and error I was able to mostly salvage this image by calibrating each light frame twice, once with darks only and the second time with darks and flats with an extra 20000 ADU added to each master flat; and then these two sets of lights were averaged together image by image to create a new set of subs that were processed into this image. On top of that many of the color subs were shot through high thin monsoon moisture clouds that came in about midnight Saturday and shut me down shortly thereafter. So there is a lot of color noise in this image. And did I mention the seeing wasn't that good? Fortunately this galaxy will be well placed for the next few months, so I plan to get better data in June's imaging trip to the Tehachapi mountains.

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.
