I captured the data set for this image on my second trip to Mahleur Field Station. The first late last year when the skies were ruined (the sky was barely visible) by thick smoke from wildfires in the Oregon Cascades and Northern California. This year, I made sure to come in spring, when only normal clouds are a problem.

The sky there should normally be Bortle 1 or 2, but for some reason we had Bortle 3 skies (an amateur stronomer in our group ran an SQM meter during our stay), probably due to thin high altitude clouds. This was disappointing, but still far superior to my backyard. I was hoping to get more of the long tidal tails, trailing off the ends of the two primary arms, but got only a hint here, probably because of this suspected sky transparency issue.

This object is a lovely barred spiral in Ursa Major. Its has many branches coming off each of the primary arms, making it look like a hybrid of a normal spiral and a barred spiral. Lots of star formation, but not too much. There are probably some nice places for a livable planet in this galaxy's outskirts. Notice the many dust clouds criss-crossing the central regions - lots of material left to make more stars and planets in the future!

Each of the 24 nine minute image was a live stack of 135 x four second subs live-stacked in SharpCap

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.
