M81 & M82

Started capturing data on 03/09/18 and finished with data acquisition on 04/08/18. Clouds, clouds, and more clouds! There has been plenty of that this spring here in north Alabama. But it's nice to finally have a little data to process after a what seems forever!

I captured 1,600 frames of L data at 20s a frame using gain of 75 an offset of 15. The frames are only 20s due to the light pollution here, any longer and the images get blown out. Really wanted to do lot's more to bring out the IFN that surrounds both M81 and M82. You can make out a little hint of IFN with the current image but it has no real detail. The IFN actually shows up pretty well in the original stretched version but I decided to not present that. It just didn't look that great from a lack of detail. Maybe next year I will capture more luminance data but now it's on to more galaxies seeing the forecast calls for a few nights of clear skies :-)

Thanks for looking!

The refractors!

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.
