With an increasingly bright moon I thought I would have one last go at an image before the light becomes too much. The weather is changing again too. I managed to take 42 subs of this at 4 minutes long each, using my Nikon D800 and my 3" refractor.

To give you an idea how massive the files are coming off this camera, it took PixInsight just under 6 hours to stack the data, and the total number of files I used for that, which includes the dark frames and so forth, were 55GB! On this computer I would only require 20 data sets like this before I would run out of space on my poor laptop's hard drive! That is why I do not keep lots of data for things like this... : )

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.
