> Pinwheel Galaxy // M101

>On the outer edge of the Mojave Desert, where the sky is super dark, you'll see things that will almost make you believe in aline spacecraft. Satellites, meteors, seemingly moving darkness that almost looks like a cloaking interstellar ship. Incredible place.

>Since it's galaxy season and I didn't think the focal length of the Redcat51 would be good enough, I busted out the 100-400mm Fujinon lens. In all and even with flat frames, it left a large vignette. It also seemed to distort stars in a way I think is best described as astigmatism, warping them around the central focal point, but I'm unsure if this is possibly due to not using the star-tracker. Still with the double gradients from sensor noise (or internal light leak) and the vignette; this was one of the most difficult edits so far and really, I'm surprised how decent it developed.

>Debating on whether to get a proper dovetail for this lens (for star-tracking) although I'm thinking probably not. Set-up I have currently I'd like to leave the same, with any improvements saved for a much better rig coming next year.

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.
