Pluto ( 24 hours shift anim ) (Wanni)

Pluto ( 24 hours shift anim )

Revision title: reloaded

This animation shows the move of Pluto in front of the background stars at 24 hours time difference.

The dwarf planet Pluto is a very difficult target, 14 mag. only.

Currently in front of lot's of 12 - 14 mag. stars in the constellation Sagittarius.

The two bright stars, Sagittarius Epsilon1 & 2, I used as broad orientation.

Hint : Look at the center of the image, a bit down-right.

The resolution of the underlying images have different integration times : 30 min. / 2 hours,

because in the first night I had to stop because of clouds.

( this can actually be seen by the length of the streak ! )

I COULD NOT IDENTIFY PLUTO USING ONLY ONE IMAGE with 100% certainty,

so I repeated the search similar as it was done 85 years ago.

HISTORICAL REMARK:

- Another planet beyond Uranus and Neptun was hypothesized by pure math. calculation. (P.Lowell)

- Lowell himself was not succesfull in his lifetime to find this new planet (Planet "X").

- 14 Years later, "Pluto" was discovered in 1930 at Flagstaff (Arizona) using a special build

"Pluto Telescope". (Lowell Observatory, C. Tombough)

(It took him more than three years to find Pluto ! And it was just luck, because of flawed calculations)

- The Telescope was a 13 inch (32.5 cm) Astrograph comprising three special build lenses.

- Images where taken on large photographic plates (1hour at prime focus).

- The discovery was made taking two images at several days (6) apart and comparing the negatives using a modified Zeiss-build blinking microscope.

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.
