Iris Nebula (NGC 7023)

I was reluctant to publish this image due to the low integration time with the subsequent noise and terrible stars (due to tilt in my focuser and poor focus). I've also pushed the processing to the limit in an attempt to bring out the dust.

I do, however, like the star colours, especially HD 201731 (a white giant showing as blue) and HD 202012 or T Cephei (a red giant showing as orange).

I will definitely revisit this target with my new mono camera once the clouds decide to go away.

Title: Added Luminance and reprocessed

Description: I've added 2h 25' of Luminance data from the ASI294mm-Pro to the original 3h of broadband data from the ASI533mc-Pro. I split the original colour data into it's component R, G and B channels and integrated the mono Luminance data which I then combined as LRGB in AstroPixelProcessor. I then followed my standard workflow using Starnet V2 and Photoshop.

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.
