NGC 3733 and NGC 3738

This pair of galaxies is located in the constellation of Ursa Major at a declination of +55 degrees.

NGC 3733 is obscured by the glare of the magnitude 5.6 orange star HD 100615. I tried to process the glare of the star to reduce it somewhat. NGC 3733 is a grand design spiral located 75 million light years away. It is 5 arc-minutes in apparent size, which corresponds to a diameter of 105,000 light years. Its orientation at 15 degrees from edge-on prevents us from seeing much disk detail.

NGC 3738 is a lovely irregular dwarf galaxy located only 16 million light years away. It is 13,000 light years in diameter. The inner region glow blue, with many star clouds seen, reflection its star-forming phase.

Several other interesting galaxy structures are seen in the background.

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.
