NGC 7023 - Iris Nebula (Jeff Kisslinger)

NGC 7023 - Iris Nebula

I was excited when I was shooting this target as I was going to have quite a bit of total integration time, more than I normally do. At one point during the nights of imaging I switched cameras, going back and forth between the ZWO ASI2600MM and ASI2600MC. I did this to test out the difference in imaging with a color camera vs a mono. I've always seen the comparison in images posted online but wanted to see for myself. At one point during the transition I must have changed the camera orientation and my excitement to process this data quickly turned to disappoint when I realized that I was going to have to make a significant crop because of the different orientations. The green channel was portrait oriented while the L, R and B channels were landscape oriented. I learned that I could synthesize a green channel in Photoshop, but decided to just move forward with the cropped version. In the end, I think it turned out OK.

Description: I reprocessed this image using the new Pixinsight spectrophotometric color calibration process and Blur Xterminator script. I was never really happy with the colors in the original image, SPCC seems to have done a good job. The Blur Xterminator script didn't pull out much more detail but did a phenomenal job with the stars.

The other reason I reprocessed this image is that it's been weeks (4-6, no joke) since I had clear skies good enough to image. This has all been the result of me getting a new mount and scope :(

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.
