<egg|zzz|egg> GradingRaptor: but Jupiter is cute
<egg|zzz|egg> yeah, it has bands at times; not very easy to see though
<egg|zzz|egg> also it's now out ow the tree
* GradingRaptor blames the window.
<egg|zzz|egg> GradingRaptor: ok, in the 2.5 I definitely see some banding when it comes into focus
<egg|zzz|egg> problem being that the image wobbles in and out of focus all the time because atmosphere
<egg|zzz|egg> probably because of air currents inside the room from the window rather than outside?
<egg|zzz|egg> not sure
* egg|zzz|egg tries opening another window to cool things uniformly
<GradingRaptor> Hopefully you're not looking across a parking lot?
<egg|zzz|egg> GradingRaptor: nah, across a garden of sorts

<egg|zzz|egg> and I'm looking at 35 deg alt
<egg|zzz|egg> GradingRaptor: mind you the 2.5 mm eyepiece is definitely pushing this scope to its eggstreme limits
<egg|zzz|egg> GradingRaptor: not in terms of magnification per aperture, because short focal
<egg|zzz|egg> but in terms of chromatic aberration and focuser precision etc.
<egg|zzz|egg> it *is* a finder after all :-p
<egg|zzz|egg> just a very fancy finder
<GradingRaptor> Any Jovian cows?

<egg> UmbralRaptor: note on the penultimate image (Kerbin-centred, sun-aligned, long duration) that the orbit does precess in a way, but not around the pole; it's just that Kerbin is tilted
<egg> and as the precession is around the pole and not the normal to the eggliptic it does that
<egg> UmbralRaptor: over several Kerbin years you get this: http://i.imgur.com/1UwWqdN.png

<whitequark> oh

<egg> comments a bit outdated too, but anyway
<egg> whitequark: so you send this in a plain text email, and then you get ephemerides for the bodies you requested
<egg> whitequark: so if you ask for a long ephemeris for one body that comes in one email
<egg> whitequark: but it comes in one email per body
<egg> whitequark: and here we want an initial state, so we get one email with 6 numbers we care about, per body
<egg> that's about 30 emails getting sent at the same time, which generally takes some time (maybe gmail is rate-limiting?)
<egg> then we have to parse that madness, which would be easy if they were all in one place, but here it's 30 different mails, so we dump them into a file with google takeaway and awk the thing
<egg> whitequark: now arguably asking it for one point and using that as an initial state is not ideal; the data that comes from those ephemerides is fitted to observations, sometimes derived from analytical models, and isn't always suitable for integration
<egg> the "proper" way to do that is to tweak your ephemerides to get a best fit of observations
<egg> but, well, fitting VLBI data is not on the yak stack nor on the bikeshed heap yet
<egg> whitequark: oh, HORIZONS also has an interactive interface
<egg> whitequark: it's telnet
<egg> telnet horizons.jpl.nasa.gov 6775
<egg> non-JPL ephemerides: IMCCE's INPOP http://www.imcce.fr/fr/presentation/equipes/ASD/inpop/
<egg> and then there's this from an IMCCE-SAI collaboration http://lnfm1.sai.msu.ru/neb/nss/nssephmf.htm
