Hello friends,

this time I present a very unusual object: The irregular galaxy NGC 4449 aka "The Box Galaxy". Inspired by @John Favalessa and his image from the Box Galaxy https://www.astrobin.com/exa1ql/?q=NGC4449 . I decided instantaneously to go for this target. It is so beautiful and unique.

Unfortunately the weather prevented me from collecting more data. I had only three partial nights to collect some data - under full moon and through clouds. Since weather forecast predicts no additional chance for the next 2 weeks, I have decided to release it based on the data I have. I have tried to make some PI "hocus pokus" to make the best possible from it.

May I also draw your attention to the two small spiral galaxies on the very right hand side: PGC040984 /6. This was a nice additional (random) catch

To enjoy the details in NGC 4449 please go to full resolution. I think, it is worth it

I hope you will enjoy it!
Rüdiger

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.
