M101 with 135mm (crop)

This is a cropped image of a very wide field taken on April 18, 2020.

Unguided, f2.8. About an hour into it.

M101 (The Pinwheel galaxy) was one of my first visual targets when I began my astro journey in 2017. The goal was to image this lovely galaxy for the first time.

Technical news with this image:

Processed and stacked *all* the lights... without chucking out any subs for the very first time in my career as a low budget imager.

This means that - my mount is working

- I used the tripod with too much height in the past (low is good)!

Every day I do this gig, I learn something new, ha ha.

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.
