Digital planner stickers goodnotes9/24/2023 ![]() ![]() I appreciate all the comments on the diffraction spikes. That said, the saturated (or nearly saturated) stars that show diffraction spikes might be slightly less elongated, suggesting a masking technique that resulted in fewer of them being stacked- not an unreasonable thing to do. Since the diffraction spikes are at 45° to the direction of elongation, we'd expect the broadening to be the same for both axes, meaning there is no simple way to detect it. Perhaps Damian can chip in here with some more technical information about the exposure and processing.Ĭousin Ricky wrote:The big question (the “incongruity”) is why the diffraction spikes are not smeared to the extent that the stars are elongated. My guess is that the tracking was on the stars, and the slight elongation is an artifact of the stacking method used to try and minimize trailing for both the stars and comet at the same time (which isn't something that can be done perfectly). That's more than the slight elongation seen in the stars (which I guess is what you are calling "tracking motion"). That corresponds to about 90 arcseconds of drift of the comet against the background stars, or about 6 pixels when looking at the full-sized image. I didn't find any technical information for this image, but based on other images I assume around a 15-minute total exposure time. ![]() The telescope Damian uses has a spider-mounted secondary, so diffraction spikes are normal. I don't think the diffraction spikes are artificial. ![]() It seems incongruent that all of the stars have tracking motion but the diffraction spikes are clear and crisp. original sound - lyriclychee.Geckzilla wrote:I presume the diffraction spikes were added for artistic effect.
