22.FEB.2023 - Celestron Edge HD 1100 + Hyperstar v4 + ASI6200MM Pro
16 x 300s Baader B 2" Filter

First Light for the new Baader O-III Super-G 9nm (CMOS-Optimized) filter
and a and first approach to a new LRGB-procedure for urban astrophotography.

On the run from LED lamps and more and more skyglow,
I try to answer the following question with this image.
What happens if the new 20nm H-alpha filter is used instead of the standard 100nm "R" filter
and the new 9nm Super-G filter is used instead of the standard 100nm "G" filter?

The result here is a “20nm H-alpha / 9mm Super-G / 100nm B“ image.
The new Baader UHC-L Booster (CMOS-Optimized) was used as L.

So three new filters are involved in this image.
It is not a multiscope image - the small FSQ-85 is not involved this time.

"Narrow RGB" filters for urban astrophotographers, wouldn't that be fascinating?

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.
