Revision title: NGC2018 V2

The clouds are finally clearing in Sydney, but only when it coincides with the full moon. With that and the clear evidence that I have forgotten the little I had learned about astro before La Nina arrived 12 months ago, it's clear that I would benefit from any constructive advice that you may care to impart.

I'm basically at the limit of the capacity of the HEQ5 with this OTA, but I'm getting 0.4 to 0.6 arcsecond guiding (which I think is OK?). I'm not sure whether the softness and lack of detail in the image is due to slight oversampling (0.53 arcseconds per pixel), or not enough data, or whether I have not quite got the right backfocus nutted out, or operator error. Or all of the above! Or I'm not processing well enough. Or it's just not worth imaging, even in narrowband, when the moon is this full and bright.

Hope you are all doing better than I am! Thanks in advance.

NGC2018 is an H2/O111 rich emission nebula close by its big brother, the Tarantula Nebula near the LMC. Most of the attention goes to big bro so I thought it would be nice to attempt something a little less well known.

Description: A bit more time and effort in PI revealed some further detail in the data and allowed a better presentation in the Hubble palette. Much improved methinks!

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.
