Hickson 44

This is a collection of four gravitationally bound, interacting galaxies. You can see the effects of interaction on NGC3187 and NGC3190. For the other two, the interaction is more subtle. I love the variety of galaxy morphologies in this group.

* NGC 3187 - distorted barred spiral

* NGC 3190 - spiral

* NGC 3185 - barred spiral with an outer ring

* NGC 3193 - elliptical

If you look closely there are many smaller galaxies in the background.

For this image, I used the ASI 294's bin 1 mode for the luminance data and the bin 2 mode for R, G and B. This is the first time I have used this classic method to acquire a color image. I connect to my remote observatory over Satellite internet. In my first month of operation, I burned through my entire data allotment. Using smaller images for the color channels is helping me to conserve bandwidth.

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.
