M105 and Environs

Here we have M 105 and its neighbors, NGC 3384 and NGC 3389. I find this to be a very beautiful trio. M105 and NGC 3384 are part of the Leo 1 group while the spiral galaxy, NGC 3389 is thought to be somewhat further away and in the background. M 105 and NGC3384 are surrounded by a neutral hydrogen ring with a radius of about 650,000 light years. Star forming activity is thought to be occurring within the ring. -- information obtained from Messier-objects.com

On this image, I tried to do a HDR approach to the luminance to see if it would enhance the elliptical galaxies at all. I don't think it did but it was still an interesting thing to try.

I'm still fighting with my stars and I think my problems may stem from a slight miscollimation. Using the simple airy disk method, everything looks perfect. So I will try Metaguide collimation routine to see if that helps.

Anyway, I hope you like my effort with this one... Clear Skies and be well !!

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.
