UGC 9749 Ursa Minor Dwarf Galaxy

Here we have another satellite of our Milky Way Galaxy, UGC9749 The Ursa Minor Dwarf Galaxy. This galaxy was discovered by A.G. Wilson at the Lowell Observatory back in 1955.

The center of this dwarf spheroidal galaxy lies about 225,000 ly away in the direction of Ursa Minor and is of very low surface brightness. It is though to be about 14 billion years old and all of the stars were formed during one burst of star formation that lasted about 2 billion years. There appears to be little or no ongoing star formation. credit Wikipedia

I imaged this on two of the shortest nights of observing in the Northern Hemisphere and I thought it a nice companion to the other Milky Way satellite I recently posted, UGC10822 The Draco Dwarf Galaxy. These are of very low surface brightness and quite difficult to pull out of the background in a natural way. But despite the low surface brightness, these two have rather large apparent sizes with this one being 27' x 16' and the Draco Dwarf being about 33' x 19'. So interesting from an acquisition perspective and not widely imaged.

I believe I have discovered the source of the flaring I have around some brighter stars. The bolts that hold the Moonlite focuser are stainless steel and about as shiny as can be. I will deal with that and hopefully I can make that be a big improvement in the stars.

I hope to find a few more of these to do in the coming months.

I hope you like this one, Clear Skies and good health...

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.
