NGC 4449 - Lucky-Imaging with 600mm Dob

Acquisition type: Lucky imaging

A Dwarf-Galaxy with a relatively low surface brightness (at least compared to typical short-sub targets) for sure is a rather unusual target for Lucky-Imagers. But thanks to modern CMOS-Cams with their low Read Noise in combination with a large and fast Telescope even these kind of objects easily become within reach.

Please note the faint stellar stream leaving the FOV to the left. This is not an artifact but a stellar stream which is supposed to be another Dwarf-Galaxy after “colliding” with NGC 4449. Since such faint details like stellar streams can be seen I would consider this result as “deep”… acquired with only 1,4sec sub length!

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.
