So, the workshop I'm currently reviewing for has two tracks, with different requirements (mostly page lengths). But there's apparently no indication which paper has been submitted to which track?
<raptop>
If the people running the workshop like the papers, they go to one track, and hate them the other?
<e_14159>
It's published/deployed methods and future work ideas, respectively.
<raptop>
Published in papers, and published in grant applications
* raptop
<_<
<e_14159>
I mean, I can pretty much guess from the content, but that's not how it's supposed to work
<e_14159>
First track is even called Papers. Second future work, though; not grant applications. Would be a good title, though.
<raptop>
I guess it's now a suggestion for future workshops

iximeow: I'm struggling with some stellar identification (specifically if the star that appears to be at the center of M 57 is in fact the central white dwarf)
* raptop
wonders how hard it would be to get some aperture photometry done with the campus telescope
* raptop
ponders grabbing stellarium or something?
<iximeow>
ooo
<iximeow>
that sounds fun
<raptop>
...obviously this means get a grant to buy ixi a fancy CCD and set of Johnson UBVRI filters
<iximeow>
yes

whitequark: basically since the point of ISO 8601 is to have consistent endianness between the date parts and the number system I would eggspect that to remain true if you made an ISO 8601-like arabic format

WeylandsWings: I'm immediately reminded of how much setup and troubleshooting a lot of goto scopes have
<raptop>
I mean, waterproof and USB charging seem like nice things (ditto phone control, but I'd hope that it also plays nice with windows/linux/osx machines)
<raptop>
huh, 50 mm f/4 apo
<raptop>
IIRC, a 200 mm f/8 SCT with similiar electronics is ~$2k?
<WeylandsWings>
eh you can get a 6" go to celestron for 700
<raptop>
s/f\\8/f\\10/
<raptop>
huh, cheaper than I thought.
<WeylandsWings>
no camera tho
<raptop>
...why do they keep on describing bad things as "defaults"?

raptop: BGR for openCV, anyone?
<raptop>
?
<SnoopJeDi>
OpenCV's preferred color model is BGR
<e_14159>
openCV defaults to BGR for images instead of RGB. Every project I've done with it, I forgot about that until I looked at images and everything red was blue (which is surprisingly hard to notice, actually)
<raptop>
hah
<SnoopJeDi>
it's all over the place in computer vision
<raptop>
Hm, nominally 3"/pixel
<raptop>
Airy disks would be ~5" across with that, so probably all the resolution you can get
<raptop>
Someone is going to be annoyed that they can't resolve the double-double
<raptop>
Pros of system: can output FITS, low read noise. cons: tiny pixels, probably RGB restricted, 12 bits per pixel
<WeylandsWings>
cons tiny aperture
<WeylandsWings>
cons reliant on the software put out by that company
<raptop>
yeah, I should have typed sensor, not system
<raptop>
And also, costs are $1-4k, so you're not saving much (if anything)
<WeylandsWings>
raptop: i was just thinking if you got a 6" celestron at 600, plus TheSkyX Imaging (which has the auto calibration though TPoint Addon) at 500, all you need to add is a camera (that can be controlled by TheSkyX) and you would have a much better set up at about the same price
<WeylandsWings>
and there are plenty of decent inexpensive astro cameras
<WeylandsWings>
and i mean if you are looking for something more than those cameras or performance you arent looking at a 2k ish set up, you need to be looking more at a 10k set up

would consider a backyard observatory a major reason to buy a house >_>

Quadrature of highly oscillatory functions whose evaluation is ill conditioned is hard

is going to assume that egg has strapped a piece of toast (butter-side out) to the back of a cat

Oh raptop scope alignment question. Why would a certain mount manufacturer want to to roughly align to Polaris then choose another star within 5 deg to center with the azel adjust before going into a super detailed alignment routine? Mount is an equatorial
<raptop>
Unsure, I'd have to guess something to triangulate on the north pole?
<raptop>
...guaranteed circumpolar star?
<WeylandsWings>
But if you don’t do it is so weird because you can get lucky and your alignment will still work or unlucky that alignment will fail
<WeylandsWings>
Maybe we just grabbed a really bad star
<raptop>
dunno
<raptop>
This is one of those things, where there is a clear reason, but unless one could see the source code or something...
