Iris Nebula

This is not my best image for many reasons. Lots of things went wrong and I captured it too late in the season. This image is responsible for the retirement of my Atik EFW2 which has now failed me too many times with the rubber gasket that goes around the filter carousel coming off leading to needing to remove the imaging train to fix it and orientation being disturbed between nights of imaging. The seeing and transparency were poor all the nights I was working on this, the target was only in the sky during the worst part of the evening since it was transiting right at astronomical dark and then getting lower as the sky got better over night rather than the reverse. One night's subs were entirely lost due to clouds coming in unexpectedly after less than an hour imaging. Processing this image was a nightmare because my luminance flats prior to the camera reorientation were lost due to a drive failure. Gradients are always a problem for me in LRGB because of how light polluted my area has become. To top it all off this was my first attempt at a dark nebula, so my processing is not very good and I should have captured more data in the color filters. This was one of the two final projects I wanted to complete with my ES127 before replacing it on the mount with my new SCA260 in preparation for working on many smaller galaxy projects in the new year. Since I'm not happy with how it turned out, I plan to revisit this target with a much better FOV on my FSQ-85 setup next year when I can image it all night for many nights and acquire much deeper, cleaner data.

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.
