A dusty nebulous filled Melotte 15

I started capturing data for this back in September and its been the usual mixed time since then. When I'd tallied up in my head that I should have a good dataset accepting I'd definitely be losing some to clouds, I was still surprised to narrow down (not that strictly even!) 27 hours of data to around 15.5 hours!

A beautiful area of sky at the centre of the Heart nebula, Mellote 15 and its surrounding nebulosity is a treat as the focal length increases. Here, I've left some green in the stronger Ha areas.

The 150P-DS is reduced slightly by the 0.9x corrector/reducer, to 675mm. Image has been resampled at the end to hit ~ 1.5"PP (from 1.14"PP)

Thanks for looking.

Captured with ASIAir, pre-processed in APP and processed in PixInsight.

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.
