IC443/IC444 - Sh2-248/Sh2-249 (Uwe Deutermann)

IC443/IC444 - Sh2-248/Sh2-249

Had to get my RASA back out after such a long time of bad weather. I split the observation time into 3 targets just to take advantage of clear skies. One of them is IC443 which was actually the very first image that I took with the RASA. This time though I added some RGB stars with the Z61. I will gather more data over the next clear nights, but since I liked already the temporary result I posted it.

B

Description: More work on noise and color adjustments.

C

Description: Added more integration time obtained through a 4 night stretch of clear skies!! It is cool and not humid right now in Florida, wonderful astro imaging nights, if just the moon would go away ... ;-). Reprocessed from scratch. I believe I should dim down the stars a bit more, next version ...

D

Description: Some more minor tweaks, I thought the reddish background was just a bit too much in version C.

E

Description: A little progression comparison. Hope I will stay on this path!

F

Description: Another processing trial from scratch using some suggested methods by fellow Astrobiners 😊.

G

Description: Less arcsinh stretch on the RGB stars than version F.

H

Description: Added app. 2 hours of OIII data and create a base H(HO)O image. Not enough for OIII, which additionally suffered from a shiny bright moon.

I

Description: Added some extra OIII data a month ago and finally found some time to add them to the image. The HO combination was done from scratch with the new OIII data, added a bunch more minutes to the RGB stars as well.

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.
