NGC 2841, The Tiger's Eye Galaxy

An interesting, nearly perfect disk shaped galaxy with tightly wound spiral arms. Very intricate dust lane patterns, but almost no active star forming regions.
The small galaxy in the bottom right is PGC26572.

Captured with a monochrome camera and L,R,G,B filters. Nearly full moon for much of the time, but it was the only gap in otherwise persistent cloudy weather. Really struggled getting a good color balance with this image, maybe interference from the moon.

Update: For Revision B I got more green and much more blue data. Color balance was easy to achieve, and there is a little more color detail.

B

Description: Added two more hours of green and four more hours of blue data, and reprocessed. The final result looks very similar to the first revision, but was much easier to achieve. The SPCC in PixInsight worked pretty well this time (using Sa Galaxy as white reference), the color is more uniform, and blue features are better defined.

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.
