The Dirty Sisters - M45

I have often enjoyed viewing The Severn Sisters through binoculars, but have always struggled to image them well from Melbourne due to light pollution and low altitude. In particular, I have always struggled to tease out the surrounding dust around M45.

Until I managed to source some better quality data. Thankyou to Scott Wall (BigScott_27) for very kindly sharing his QHY10 OSC data on AstroBin.

Acquisition details as follows:

Location: Connecticut, United States

Telescope: Celestron EdgeHD 8

Accessory: HyperStar 3 lens

Camera: QHY10

Frames: 39 x 15min

Integration: 9.8 hours

Wishing you all a happy Christmas season full of clear skies … and clandestine astrophotography equipment purchases!

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.
