<e_14159> Do you know what the biggest practically-achievable f-number for a lens is?
<Iskierka> biggest n in f/n or biggest aperture?
<e_14159> The former.
<Iskierka> presumably planck length / universe radius, in theory, then?
<e_14159> Let's call this a first upper bound :-)
<Iskierka> smaller just matters how much you can make the hole smaller with a longer focal length
<GreeningGalaxy> sticking universe radii and planck lengths into optics models seems like it's not going to end happily
<Iskierka> okay, so smallest hole you can reliably get your choice of light through

<GreeningGalaxy> MARS! [mars.]
<UmbralRaptor> e_14159: So large as to be a huge hassle to use.
<UmbralRaptor> Lots of small refractors right now are about 10-15, and I think you can find some f/20s
<UmbralRaptor> Historically, telescopes went even longer due to optical problems of the era,
<Iskierka> really when you have reflectors and correct focal distance is there any reason to go for larger f-stop?
<UmbralRaptor> Very bright objects.
<Iskierka> shorter exposure

<UmbralRaptor> … I may have misunderstood Iskierka's question.
* UmbralRaptor thinks ? not ?
<UmbralRaptor> related: will any of you be near Lawrence on Saturday or Rolla on the 21st/22nd?
<UmbralRaptor> *unrelated
<Iskierka> UmbralRaptor, or both. so long as what's on the other side won't get vaporised, why not go as big as you can always?
<UmbralRaptor> Serious answer: cost, more hassle, saturating detectors on bright objects.
<UmbralRaptor> So, yes. As big as possible.
