NGC891 - The Edge of the Galaxy

Welcome to the edge of the galaxy...NGC891. Normally when galaxy images are shown they are oriented in what is called a "face on" orientation. Imagine a piece of paper, face on view is to look down at the whole sheet but edge view is to just look at the edge of the paper. NGC891 is an edge on galaxy.

I just caught a break in the weather last night ( before 3 days of rain forecast ) so I saw that NGC891 was up and imaged it for about 6 hours.

Some wikipedia background:

NGC 891 (also known as Caldwell 23 or Silver Sliver Galaxy) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784.[3] The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster. It has an H II nucleus.[4]

The object is visible in small to moderate size telescopes as a faint elongated smear of light with a dust lane visible in larger apertures.

In 1999, the Hubble Space Telescope imaged NGC 891 in infrared.

In 2005, due to its attractiveness and scientific interest, NGC 891 was selected to be the first light image of the Large Binocular Telescope.[5][6] In 2012, it was again used as a first light image of the Lowell Discovery Telescope with the Large Monolithic Imager.[7]

This was taken with an ASIAIR Pro, an ED153CF refractor, a ZWO ASI183MC pro camera and an Optolong L-Pro 1 1/4" filter. It is a stack of 35, 5 minute images.

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.
