M101 Core (Rodd Dryfoos)

M101 Core

I wanted to see how much detail could be picked up in the core of M101 with a 5" scope. M101 always looks dirty when I shoot it--a mess of undefined scragginess. I wanted to see what actually is in there! I think under pristine skies with no LP the results would be quite good. This is a tough target for a variety of reasons, low dynamic range across the disc is one of them. So I feel this is a pretty good example of what a 5" scope is capable of in poor skies. I don't think there is too much more to get out of this data, at least not with my processing skills. I do love the TOA 130--but I think I am feeling the inexorable pull of the 11". I think its time. I am building up my courage for some 2,800mm imaging. Galaxies, naturally, will be the primary targets, including M101. It will make for an interesting comparison. An interesting fact is the FOV depicted in this image is WAY closer in than even one taken at a focal length of 2,800 mm with this camera. Now that is quite a crop! I know there is some noise - I am trying to deal with it. Might be only so much I can do.

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.
