NGC3718 is probably my best galaxy image published so far and quite possibly my best ever. This in part due to fortuitous set of circumstances where not only the sky was clear but was clear with good seeing for quite a long stretch of weeks in 2009. Part is due to the subject itself, the nearest thing the boreal celestial hemisphere has to Centaurus A (admittedly on smaller and dimmer scale but still formed by the same process, that of tidal disruption). The key thing I had in mind was to bring out the tidal elongations of outer regions of the galaxy which are WAY fainter than the main body, while preserving the ghostlike quality of the whole and the band of dust at the centre as it is stretched under the gravitational pull.

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.
