NGC4631 The Whale

NGC 4631 is an edge-on spiral galaxy in the constellation Canes Venatici. This galaxy's slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname. Because it is nearby and seen edge-on from Earth, this galaxy provides better understanding of the gas and stars located outside its plane. NGC 4631 has a nearby companion dwarf elliptical galaxy, NGC 4627.(Source Wikipedia).

Used the Meade 12"LX200 at F7.5. Employed 80 subs at ISO1600 and 5 minutes and 10 minutes each (11.83hr) on 4/23 (18 at 5m and 9 at 10m), 4/24 (18), 4/25 (18), and 4/27 (17). Processing was done with PixInsight. This is a slight crop -- North is up. This is intended as the final image.

Not a bad result, but somewhat disappointed that the amount of integration time did not bring out a better image.

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.
