Antlia Galaxy Clutch

This is a preliminary study using my smaller 200mm DSO setup. Most of the data was collected as a by-product of trying to sort out tracking problems with the mount (still not well, alas). I'll come back to this target with my bigger scope because I can get better details in the galaxies and add Ha data. Nonetheless it turned out much better than I was expecting.

The two brightest galaxies NGC 3347 (magnitude +11.2) and NGC 3358 (magnitude +11.3) are located in the southern constellation of Antlia. NGC 3347 is a barred spiral galaxy, while NGC 3358 is an irregular galaxy.

NGC 3347 and smaller NGC 3354 (magnitude +13.2) are in the process of merging with each other, which has resulted in tidal distortion of their shapes. This can be seen in the elongation of the spiral arms of NGC 3347 and the faint tidal tails extending between the 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.
