William Optics Redcat 51, ASI183MC-Pro with 2" Ha narrowband filter by Svbony.

Mount: Skywatcher AZ-Gti in EQMOD, fw. downgrade to 3.20 from actual latest 3.26 to support PHD2 guiding in Astroberry server (Raspberry Pi4, 4gb).

After some attempts failed, according to some bugs reported for incompatibilities among astroberry>Kstars/PHD2 guiding, I downgrade my AZ-GTi to firmware 3.20, since then getting able to perform very quick calibration and autoguiding both in PHD2 and internal Kstars.

This is an integration of some Ha subframe taken at 300sec, Gain180, -15C with ASI183MC-Pro on WO Redcat 51 from home balcony, Bortle 6 urban sky.

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.
