Eleven-Day-Old Moon (85%), July 1, 2020 (w/ PSRS)

A prime-focus image at ISO 200. The exposure time was 1/250th of a second. However, this image was actually created from four exposures automatically taken in quick succession after pressing the shutter by a super-resolution feature called Pixel Shift Resolution System (PSRS).

PSRS uses the camera’s sensor-shift mechanism to move the sensor to four adjacent pixel positions in order to capture complete color information for each pixel, avoiding a resolution loss from demosaicing. It also doubles the SNR. The result is a sharper, cleaner image than is possible with a single exposure, provided that atmospheric turbulence is low. The telescope also needs to be tracking.

All four exposures also use an electronic shutter, which avoids the shutter shock that normally blurs fine details at least as much as atmospheric turbulence. Note that a mirror-up shooting mode was used, so there were no vibrations due to mirror slap.

The Meade MTS-SN6 is a 6-inch f/5 Schmidt-Newtonian telescope from the 1980’s.

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.
