Outer regions of NGC 2841

This is a very deep image which shows the faint outer regions of NGC 2841 galaxy.

The outer halo of the galaxy is brighter in the B channel compared to R and G. Apparently it consists of young hot blue stars.

The galaxy apparent size including the halo on this image is about 14 arcmin. The distance to the galaxy is estimated to be 46 million light years, i.e. the halo is about 180 thousand light years across.

This project took 32 clear nights in November, December 2021 and January 2022.

PhotometricColorCalibration with K0V star as a white reference has been used. This means that the galaxy colors are shifted to the blue part of the spectrum. Using the usual F8V star as white reference has produced a very red galaxy.

This image was an APOD on 3.03.2022.

Enjoy!

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.
