NGC 5216 - Arp 104 'Elliptical Connected to Spiral'.

Here's an Arp galaxy interacting pair. It's Arp 104 and is classified as

'elliptical connected to spiral'. You can see the bridge of material connecting

the 2 galaxies in my image. I don't know if it's unusual to see an elliptical

interacting with a spiral galaxy but I think this is a splendid example. It

would be great to 'pop back' in a few million years to see what's happened to

the 2 galaxies!. Arp called this pair Keenan's System.

This image consists of 10 x 4 mins, 5 x 5 mins and 5 x 6 mins. I did a sigma

combine on each batch then balanced the backgrounds and average merged the

resulting images. A total of 95 minutes exposure. I had a lot of trouble

processing this one, I don't think the seeing was great and it never gets truly

dark this time of year, plus it's pretty faint.

The spiral is ngc 5218 and is mag. 12.3, 2.9' x 1.6' and SBb? pec.

The elliptical is ngc 5216 and is mag. 13.6, 2.4' x 1.8' and E0 pec.

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.
