Milky Way Core

Milky Way core from Lysterfield, Melbourne.

Nikon D610, Nikon 50mm (f1.4) shot at f2.6.

Stack of 107 frames x 10 secs (17.8 mins exposure).

This 2nd test of a 50mm lens was on a moonless night this time, from Mebourne’s outer suburbs. My 1st test a week ago was when the moon was bright and near the horizon which reduced contrast, and used less integrated exposure. So this time the detail is better. Next step is to accumulate several panels from a dark site to cover more area, since the resolution seems reasonable with this El Cheapo $150 Nikon f1.4 Lens.

It’s nice (quicker and easier) to do traditional photography for once without needing to set up the telescope, the night sky offers something at all scales.

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.
