NGC 2841 - Tightly Wound Spiral.

And here's another from May this year, ngc 2841, another quite difficult

subject because it's arms are so tightly wound. I got around 60 x 60 sec unguided

exposures on this one when it was favourably placed and never got around to

posting it.

It's really quite a bright galaxy at mag. 9.9 and has a highish surface

brightness of 12.4. It's quite a good size, 8' x 4' so why is it so difficult to

resolve? It's a Seyfert Galaxy, very active and it's arms are really tightly

wound up. So tight that they can only be resolved on really good sharp nights. I

may have got a reasonable night here because there is just a hint of the arms

being resolved. I've tried many times to image this one but this is about as

good as I can do.

Sigma combined and unguided, I'll try it again next year with longer subs and

we'll see if there's any improvement.

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.
