M63 Sunflower HRGB (SV130 2024)

My third time imaging M63, but my first time imaging it with the SV130 setup. I struggled with flats: even though I appeared to have textbook exposure, and I could see the dust motes and vignetting in the master flats, I still wound up with very pronounced vignetting on the integrated masters. I had an issue at first with the filter wheel not reaching the same position for flats, and creating embossed donuts, but luckily I imaged over four consecutive nights, and I could correct for those on subsequent mornings by retaking flats and fixing the rotation direction.

We had a wonderful streak of 4-5 clear or mostly clear nights, so I was able to setup my two rigs and leave them out all week. A rare treat, indeed! This was only my second broadband image on the SV130, and I am pleased with the result. Still imaging from Bortle 8, so any broadband result is better than nothing! The observatory plans are coming together hopefully soon, and then maybe we can start construction in the summer or fall. Until then, it'll be Bortle 8 for a while.

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.
