<iximeow> raptop: why would a CDK have a split diffraction spike like https://cdn.discordapp.com/attachments/683591397529616398/799523435361075200/Selection_999148.png
<iximeow> it's only along one axis which is highly confusing
* raptop is confused also
<iximeow> it's also symmetrical so it's consistent across both sides of the secondary? i don't even have a guess
<WeylandsWings> iximeow: what does the spider look like?
<WeylandsWings> Or maybe yo have a no kidding web and live spider in the scope
<iximeow> i see no reason for a double line!
<WeylandsWings> iximeow: if I had said “have you checked on the spider recently” and left it at that, only me you egg and raptor would have gotten it
<iximeow> lol
<WeylandsWings> Also it looks like the image is pretty saturated around the bright object. Could it be blooming in a weird way
<iximeow> that's definitely possible. i haven't seen it on dimmer (but still bright) stars but i'm not yet certain they don't have long enough spikes to see it
<iximeow> either way, i'd like to find what's doing this :|
<iximeow> increasingly distrustful of the lrgb filters i have, too. that would be weird here, but not impossible
<iximeow> actually. if it's a weird polarization(?) thing from the filters i can rule that out by changing the rotation and seeing if the pattern changes.
* iximeow waits 20 minutes for an answer
<iximeow> ! it does not move with rotation !
<raptop> I guess that points to the saturation hypothesis
<iximeow> it could also be a weird defect in the filter. i'm going to see if this remains in non-L
<raptop> *L*?
<raptop> As in something near WISE W1 or IRAC channel 1?
<iximeow> if only. i had a light pollution filter that i thought, sure, what harm is it gonna do rejecting sodium or whatever? and it's a seven slot filter wheel, so what else would i put there?
<iximeow> (what i would love to put there is a 2" diffraction grating. that would be rad.)
<iximeow> oh
<iximeow> this might be the vanes not being perfectly parallel.
<raptop> hrm
<raptop> since I don't know Chinese, I assume that the green lines are nebular emission ones, and the orange are common light pollution (eg: sodium and mercury)?
<iximeow> yeah
<raptop> It's actually pretty cool that it's possible to make a filter with that response curve
<iximeow> yeah! i'd love to learn a bit more about filter design one of these days
<iximeow> my extremely unscientific "draw lines in mspaint" methodology has me thinking that, indeed, the vanes aren't quite in line

* raptop stabs dielectrics
<raptop> Don't worry, they're ideal dielectrics in a vacuum, and the one that's giving me trouble right now is even a sphere!
<raptop> (it's not a cow, though)
<raptop> Anyway, a point charge q is in free space a distance d from the center of a dielectric sphere of radius a (a < d), and dielectric constant ε/ε0. Find the potential at all points in space as an expansion in spherical harmonics
