From the Earth to the Iris

After the Jones Emberson 1 planetary nebula hid behind the roof of the house, I had about 1 hour before the sun starts to show its light. The Iris Nebula was right in front of me and I used it as another test for my new RC8, for 1 hour.

Even with the nice CLS filter from Astronomik, used as a Luminance filter for my monochrome ASI183MM pro, it is not sufficient to get the nice details I obtained on my former shot of the Iris (11+ hours in total, in LRGB), with the 350 mm from TS Optics.

I used the chrominance of my previous shot with the 350mm to put colors on my little hours of CLS with the new RC8. Chrominance can be heavily undersampled if the luminance is good. Well, in this case, there were lots of noise in both of them (and I didn't even make the flats for le Luminance).

Anyway, it is fun to put those 3 shots of the same region in perspective : from Earth to the Iris (from 27mm FL to ~ 1100mm, with the reducer).

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.
