Firstlight ESPRIT 100ED @ M101 Pinwheel Galaxy

Back under Bortle 5 skies...

The image shows a first-light result of my Skywatcher ESPRIT 100ED, which recently became part of my equipment.

Comparing this version with my very first attempt at M 101 - Pinwheel Galaxy more than two years ago puts a little smile on my face. Back then I was so thrilled with my first picture of a galaxy... and the excitement keeps going

The PGC annotation always amazes me, too, how many small (star-like) objects turn out to be distant galaxies.

Messier 101 (also called NGC 5457, Pinwheel Galaxy or Firewheel Galaxy) is a spiral galaxy with dimensions 28.8' × 26.9' and apparent magnitude 7.5 mag in the constellation of the Big Dipper. Its distance is about 16 million light-years, its diameter 170,000 ly - credit Wikipedia.

As always, thank you for dropping by and/or leaving a comment which is greatly appreciated.

Stay well!

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.
