Messier 44 - Widefield @ 135 mm

Hello star friends,
this time I only have something profane, Messier 44 as widefield.

I wanted to test guiding with spiral dithering in PHD2. It seems to work better with the short focal length than random dithering.

from wikipedia :
Messier 44, M44 or Praesepe (Latin for nativity scene, in English also "Beehive" for "beehive") is the name of an open cluster of stars in astronomy, which can already be seen with the naked eye as a nebula in the evening winter and spring sky. The celestial manger - a kind of glimmer between two stars in the constellation Cancer - was once also used for short-term weather forecasting because it becomes invisible in cirrus clouds.

This star cluster is the second brightest star cluster in the Messier catalog after the Pleiades and stands out in its position because there are no stars brighter than 4th magnitude in Cancer. Although the star cluster of the relatively close Hyades is even brighter, it cannot be recognized directly as a star cluster with its apparently widely distributed stars.

Thanks for watching and stay healthy !

CS, Wolfgang

- I close the lens to f/5.6

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.
