THE PINWHEEL

Located 25 million light-years away in the constellation Ursa Major, this magnificent galaxy, with its vast regions of bright nebulosity, is roughly twice the diameter of our own Milky Way and is estimated to contain one trillion stars.

⁣This image was created with data captured across 7 nights from April to May, 2022 using a 120mm diameter refractor telescope and a cooled, monochrome camera with broadband and narrowband filters.⁣

I consider this image to be one of the worst I have captured in the last two years. I made the mistake of having my field flattener backspacing off by 20mm and I didn’t realize it until I began to process the data! Each RGB filter ended up being effected slightly differently which resulted in the stars having colour shift after channel combination. This could not be resolved no matter how I tried to align or correct for any distortion. Lesson learned! 🥳

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.
