Iris Nebula

After seeing some nice images of the Iris Nebula here on Astrobin from light polluted skies, I decided to give it a try. With my setup (listed in details) I captured data over the nights of October 18, 19 and 23. The QHY268c camera was set to high gain mode (mode 1) 0 gain 20 offset. I managed 450 images at 2 minutes each. This was my first real imaging attempt with my newly acquired FSQ-85ED with Flattener. I also used my RST-135E mount for it first real imaging (up until now I was just using it to run gear tests, getting settings dialed in and really just learning its quirks and strong points). All in all, I am pretty pleased with how it turned out. There is some minor tilt and possible backspacing issues to be worked out in the imaging train, but it is getting closer. Obviously a lot of data to combat the light pollution is needed, but I feel my processing has improved as well. I have been slowly working through Adam Block’s Pixinsight tutorials, so very helpful. Baby steps, baby steps and someday bigger steps!

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.
