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 NGC1931 "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.
