Iris on the Side (NGC 7023)

This season I've been concentrating on galaxies, of course, but my primary targets generally set behind my house by 2:00 am or so, leaving me with a couple hours of unused darkness. These are potentially the best hours of the night, since neighbors tend to turn out their lights before bed, reducing overall light pollution.

To make use of this time, I've been experimenting with the ASI Air Pro's Plan mode, which allows enables the telescope to move from target to target throughout the night. What a boon for astro-productivity!

So in addition to my Galaxy Season projects, I've been capturing an Iris on the side. The Iris Nebula (NGC 7023) rises just over my northern neighbor's house just as the galaxies are setting, and I've been able to collect just over 7 hours of useful data on it over the past few weeks (and quite a few hours of bad data too).

I am a little disappointed that 7 hours of imaging didn't reveal more of the brown dust surrounding the reflection nebula. Perhaps that was too much to hope for in my Bortle 8 skies, and perhaps my annual summer visit to a Bortle 4 area will yield better data.

Aside from that, I'm pleased with the richness and color I was able to capture--with very little effort!

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.
