Messier 16

It is getting harder and harder to image now, the nights are so light. I lost astronomical darkness several weeks ago, and being someone who struggles with serious fatigue anyway, starting this up at 11.00 every night, requires some doing. Needless to say, this was a bit of an effort, my first version being thrown out. And so I used Starnet++ for the first time - I am happier with this result - although there are some oddities in the image round certain stars, because of the way Starnet works, or more likely how I use Starnet! So, this was 48 subs, 5 minutes long each, with only about 20 being reasonable - thus 4 hours integration time. I used my SCT duo-band filter - so this is effectively a HOO image. Indeed, from my garden there are so many trees in the neighbouring gardens, that I am literally scraping the top of them, imaging anything lower than -13 declination is impossible. This is such a frustration because lovely targets like the Lagoon and Trifid are out of my reach! There is one tree, and I do have a chainsaw... If only! Thanks everybody...

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.
