M106 widefield - Zenithstar 80II ED

Revision title: A little bit brighter

After imaging M106 up close at f10 in my 8” SCT, I offer you a wider field with my Zenithstar 80 II ED refractor. This is likely my last galaxy of the season, with nights getting short, and the moon already at 50%.

The outer envelope of this giant spiral is somewhat shy, and really needs a good deal more integration to show off. I’m not sure that scaling and aligning this with my previous image will be feasible, so this may be it.

I was plagued with an intermittent haze and many satellite trails, losing several subs to the brighter ones. I missed a number of galaxies lower right of M106 - not the best framing.

Title: Stacked in ASTAP, processed in Startools

Description: The best 60% = 45 x 180s subs aligned, calibrated and stacked in ASTAP and processed in Startools. A much cleaner image, which I'm happy with.

Title: Tweaking

Description: Reprocessed the original with a little more deconvolution - I think a tiny bit more detail... but nothing to get too excited about.

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.
