M101 Pinwheel: First light with WO FLT 132

First light with my new telescope (William Optics 132 FLT). Not perfect but a start to get the field flattener dialed in a bit better......

Near the handle of the Big Dipper (or the tail of the bear Ursa Major if you prefer) is M101 also known as the Pinwheel Galaxy which is about 21 million light years away from us. This galaxy has about a trillion stars within it, nearly double the number of the Milky Way. Besides this beautiful face-on appearance to this galaxy, another interesting thing to note is that is not symmetric. This is due to the strong gravitational pull of galaxies around it, perhaps with even prior collisions. If you want more proof, look at the much smaller dwarf galaxy NGC 5474 towards the upper right of this image. Note that its central nucleus is off center and pulled towards our Pinwheel galaxy. These gravitational forces lead to explosive regions of star formation in both galaxies.

This image represents only about two hours of image integration as there is much more to do to get this scope setup for longer imaging sessions.

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.
