ngc 4631

From 2006.

I thought you might be interested to see my image of ngc 4631, the 'Whale' Galaxy in CVn. The 'Whale' is a huge edge-on type Sc spiral galaxy and it is interacting with it's companion galaxy ngc 4627 visible at the top of my image. The pair together are known as ARP 281. As they are close to us, 25-30 million light years, they are quite bright, ngc 4631 is mag. 9.5 and ngc 4627 is mag. 12.9.

Just out of the frame is the highly distorted galaxy ngc 4656 which is interacting with 4631 and will be the subject of investigation next clear night.

I took this shot last week when the sky cleared for a couple of hours. Time I'd got the telescope set up, the camera cooled down and all the software procedures, like finding, centreing and focussing sorted out, the clouds began rolling in and I only managed to get about 25 minutes exposure and most of that was through increasing cloud. All very frustrating.

Still here's the 'Whale' for what it's worth.

Acquired through my 10" f/4.8 newtonian and SX MX5-C camera using Astroart for acquisition and processing. 25 minutes total integration.

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.
