M105

A few cloudless and moonless nights last week and I was able to image this trio of galaxies in Leo from suburban Perth.

All three of these galaxies are similar distances away - around 32 million light-years, and show some of the different morphologies galaxies display. The rightmost one is named M105, and was the only one noticed by Charles Messier in the 18th century. This is a classical elliptical galaxy and is very well studied. The top one, NGC 3384 is a barred elliptical, and the one low left is a normal spiral galaxy. Some of the faint star forming regions in NGC 3389 are visible as pink spots on it's arms, and intriguingly it looks like a classical spiral shape, without the usual tidal distortions you'd expect when so close to the other massive elliptical galaxies.

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.
