M8 - the lagoon nebula

Well it was a night of frustration. I got a break in the weather, and went ahead with imaging this, as I mentioned before. Alas, I did not realise that the focus had fractionally slipped, and the collimation too, and so all 22 subs were slightly 'off', and thus the image I hoped for was somewhat lost. I have applied some extra bias and unsharp mask just to bring it up, but 'up close' it is not what it should be. I am quite disappointed. We will put it down to that thing called 'experience'! I used my modified DSLR, an 8" reflector and PixInsight as normal.

The lowness of this object, and the very limited sky I have to image it in, the time of year, the weather and the gradually increasing moon, may mean this is my last chance to image this again - at least here at this temporary accommodation - I am not sure how the garden will be in the next home I will live in. We will have to see...

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.
