Revision title: NGC 3718 cropped

This little galaxy is far too small for my 550mm setup, but it is one of the few targets left late at night when all the decent nebulae have dipped below my horizon, so I have been collecting this as a secondary target for quite a while. I checked recently and had 230 x 10-minute images so figured I had better process it...

I selected the best 163 images and drizzled x3 to squeeze as much resolution as I could and got this. I think when I invest in something that can get me over 2000mm focal length I'll have another go...

I did compare the drizzled outcome with a non-drizzled NSG version and drizzled was much better.

I have also cropped heavily into a tiny galaxy, NGC 3756, that was also in my frame.

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.
