NGC 3631 - Faint Face-on Galaxy.

Here is ngc 3631, a rather nice face-on galaxy that is not as easy as you might

think. I've tried this on many previous ocassions and not got a lot to show for

my efforts. This is definitely the best yet.

Arp was mainly interested in the 'heavy arm' to the North and extending

Eastwards in my image.

This is actually quite a long exposure (for me) and consists of 35 x 180 sec

exposures sigma combined in AA3. I had to do a bit of background work to get rid

of some uneven illumination which seems to have suddenly cropped up in my

images. Bit annoying but probably I need to pay more attention to collimation

and getting the camera normal to the light path. Or it may just be the dreaded

condensation which plagues me constantly!

Not too bad - don't know what actually caused the straight arm, not much sign of

any interactions going on that I can see, although the straight arm does appear to point towards a small blurry blob on the extreme left of my image. Must have been a long time ago.

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.
