M94

M94 (NGC 4736) is 'high in the sky', and an easy galaxy to find at this time of year. At 16 million LY from us it presents little detail in the eyepiece, in part due to a bright core. Longer exposures help to bring out the detail, and you start to see why it is known as the croc's eye or cat's eye galaxy.

Capturing the surrounding halo, whilst avoiding burning out the core is a challenge and really needs layering of images of different exposures. My image is based on 90 mins exposure using 15min subs, and with excessive sharpening, only just starts to draw out the detail, but not the outermost arms which are only seen in the largest aperture pictures.

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.
