M11 The Wild Duck Cluster

The Wild Duck Cluster, an open cluster in the constellation of Scutum and is 14' in diameter, about 1/3 the size of the full moon. It has a total magnitude of 6.3 and is visible in binoculars. Distance to the cluster is reported in the Sky Safari app as being 6,100 light years away. M11 is one of the richest and most compact open clusters. M11 is so rich that it resembles the looser globular clusters, but it is in fact an intermediate age open cluster, 250 million years old.

Telescope; 12" LX200 with the Lumicon Giant Easy Guider Reducer, running at f/6.3 thereabouts.
Camera; Canon 60D unmodified, no filtration
396 15sec light frames, ISO800, total integration of 1hr 39mins
50 dark-flats, ISO 100 1sec each
50 flat frames ISO 100 1sec each
41 dark frames ISO 800 15secs each
No guiding was performed, only the tracking of the mount with occasional re-centering of the object as needed.
Siril was used for stacking, Pixinsight for processing of the fits file, with an initial crop, DBE, image solver was used then SpectralColorCalibration, EZDenoise was preformed and then BlurXTerminator was used. GHS for stretching the image, Starnet2 for starless process then the starmask and starless image was processed separately in Photoshop and recombined with Screen Stars in PI, software by Bill Blanshan and Mike Cranfield.

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.
