M81 & M82 - First Light with my First Telescope

Revision title: SVX102T

The original photo was my first attempt at imaging the Bode's & Cigar galaxies with a stock mirrorless & kit lens from my urban backyard (45min integration, Bortle 9, DSS, Affinity Photo).
The revision is first light from my SVX102T with an EOS RP mirrorless, from a site bordering between urban and suburban (50min integration, Bortle 6-ish, PixInsight).

The revision is boasting its full, dirty glory, which I think was due to movement of dust motes on the sensor between light and flat frames. Maybe some mishandling of the calibration acquisition or preprocessing as well. When using lenses in the urban backyard, I'd never exposed long enough under a dark enough sky to see all my sensor dust. But oohhh boy, the newer full-resolution file looks like it was peppered with a shotgun blast. Mostly cleared up the issue with a rocket blower, and it's time to practice flats exposure and actually taking them at the same time as the lights.

Still getting the hang of proper calibration frame acquisition and data handling in PixInsight, but all in due time.

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.
