The UK's 'Clear Outside' app forecast a 5 hour slot of clear skies last night for south Devon - the first for 3 weeks and likely the last for 3 weeks to come :=(. So I took the chance to grab some Ha (although seeing was barely acceptable, beggars can't be choosers etc) and I have an optimistic thought that I'll be able to capture some further Ha and then RGB as the moon cycles through its phases . . . Bob Hope perhaps!

Just a quick process really however this target does stand up well as a mono. These two nebula are often over shadowed by their more frequently imaged neighbours (Flaming Star and Tadpoles) or often captured with a widefield view of this magnificent area of sky, losing their intricate detail. I seem to recall it was Swag72's image of a few years ago which first brought them to my attention and I've wanted to image this pair with my FLT132 since then: thanks Swag. There are plenty of spiders in my obs too, time for a winter clean sweep!

About 10,000 light-years distant, both represent young, open star clusters formed in interstellar clouds and still embedded inglowing hydrogen gas. For scale, the more compact NGC 1931 "The Fly" is about 10 light-years across.

Thanks for looking! C&Cs always welcome.

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.
