M81, M82 Bode's Galaxy

This is probably as dark as i want to go in this image. I kept thinking there was a gradient down there until I learned there is actually stuff (maybe nebulosity?) that the sensor is picking up. It does look like a vignette. It still might be, I have no idea. It's staying. I'm learning that seeing has to be pretty good for sharper galaxy images. 15m light years is a long way to go. I didn't mess with the color too much, I did keep it on the cooler side. This is a set of exposures with the D800 as RGB and an asi294mm as luminosity. I really blew out both images too. Galaxy images don't really need too much exposure. These are 180s. Just learning how to read the FITS histogram. Now I understand where a "normal" exposure is. No obstructions for the location of M81 from the backyard. I have a clear view to the north. sans clouds. I don't have total integration time here yet. I'll figure it out and post soon. Thanks for looking.

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.
