It literally did not occur to me at all that, because of atmospheric disturbances, it is not actually possible to image stellar objects to a resolution of better than about 0.4 arcseconds, which you can achieve with about a 12" telescope mirror. The reason why large mirror narrow field telescopes do not exist is because there is no point; you will not actually be able to get any better resolution than a similarly equipped wide-field telescope.
To restate, the problem is that the optics and the image recording medium are higher fidelity than the universe, or at least the part of the universe we can see through our atmosphere, and so it's perfectly okay to throw away some of the resolution.
I'm beat. And I'm scheduled to go in again this evening to get some C41 printing done. Oy. At least it's fun.
Good news: four more rolls down.
Bad news: hike photographs are not among them, instead being in the roll that was still in my little film collector.
Good news: development time for FP4+ is almost the same as for Plus-X in Ilfosol-S. So I can batch it all tomorrow night and still be able to print hike photographs on Friday night.
So a while back, I bought a Beseler 45 enlarger, which seems to work delightfully. I start looking around on eBay for accessories for it (first and foremost, film holders so I can print something other than 35mm on it), and notice a dichoric (color) head for it, and buy it. It comes in yesterday, I put it on the enlarger, and it doesn't work. Confused, I fiddle to no effect, and finally email the seller who disclaims all responsibility and says it worked for him.
Unthrilled by this turn of events, I take the top off and start poking around, and sure enough one of the circuit boards inside is moving around in a rather alarming fashion. I take the head halfway apart, spent about ten minutes trying to reseat the damn board, and then put the thing back together and sure enough, it works. I'm missing one entire LED on the magenta, I think, but I can probably work around that, or perhaps it's another pin disconnected or something.
My theory is that the external screw to hold the loose board in place went walkies long before the head reached the seller, and the process of shipping jarred it out of placeâto support this, there were a number of bent pins that I had to straighten out.
Anyway, I'm off to buy a timer cord for it so I can use the bastard.
( Things probably nobody but me is interested in )
I'll bring the prints I made to Amorette's birthday party, if anybody wants to see 'em.
In other news, I think the battery on my old Palm finally stopped being able to recharge reliably. This is sad, but it is five years old (and has outlived at least three hard cases, which get beat to hell!). So I got a new Palm T|X. It seems nice enough except for the part where I can't get it to sync reliably. That appears to be a Mac side issue, though, that I've been able to work around so far.
