Day 4 selfie! (omg so ready to be done with traveling for a bit)

AASelfie

Kind of great when you get to the other side of a wave of dysmorphia and realize that you actually might be kinda cute

Sept 2019 to this morning; #throwbackthursday #trans

Why don’t dentists give toys anymore? When I was six I had so many slinkies so idk how they were supposed to incentivize good hygiene. Now I have no slinkies and I’d gladly floss five times a day for a slinky

Im okay with them being teenage, mutant, and ninja, but they’re definitely tortoises, not turtles and I’m tired of pretending they aren’t

The hardest part of not being out as trans to my officemate is making jokes that are 1000x funnier in the context of my transexuality but which ultimately fall flat

@DivineKestrel @rooster lol it’s been a couple years since I came out at work so I don’t really remember the last time I had to disclose that I’m trans there (aside from once when I was trying to coax a student out of the closet)

@DivineKestrel @rooster for potentially useful context, left is the day before coming out at work many moons ago and right is yesterday

@thomasfuchs What sorts of magnitude limits are typical for astrophotography setups? (I know this is extremely dependent on a lot of parameters, but I literally have no reference for what folks can do in their backyard)

realistically I'm wanting to look at extended objects which peak at like 15-16 mag/sq arcsec which is screaming bright for big telescopes but seems like maybe a bit too dim for something I can get my hands on

@apalu @thomasfuchs yeah, I was kind of thinking about sdss r and g, which are both kind of broad. Part of my motivation for taking photos myself is actually that the sources are bright enough that the sdss images look awful and are a bit saturated and I'm pretty sure I could do pretty well with a cheapish telescope and my camera.

But I also really like a couple of the hst filters for no rational reason so they could be fun to play around with

@apalu @thomasfuchs yeah, that'd be the reasonable thing but I'm just looking at sdss images which aren't necessarily timed for the individual sources on their plates, so sometimes they get really nasty when there's a bright source.

This is a project mostly just to make a pretty picture for my wall so I assume I'll be able to get by by reducing the aperture from what sdss uses (2.5m i think?) down to whatever I can afford and tinkering with exposure times.

Idk honestly this is maybe just me looking for an excuse to dabble in astrophotography

@apalu @thomasfuchs Ahh, ok yeah I guess I was imagining the filters being comparable width to the camera's bands, but that's probably not true. That makes things a lot easier lol

@thomasfuchs I was thinking that'd be the easiest way, but wouldn't you wind up effectively getting the product of the transmission function associated with the filter and something associated with each of the three RGB channels on the camera's chip? Usually telescopes just use monochromatic ccds with known and broad response functions so I don't really know how to deal with the narrow color channels in a dslr

Question for astrophotography folks:

Is there any reasonable way to shoot with standardized filters with an off the shelf dslr? I have a home decor project in mind that id like to use a standard SDSS g and r for (or maybe a couple of the hst filters depending on how I’m feeling). But like I don’t really wanna be constrained to Nikon’s R, G, and B filters.

#astrophotography

Not an original thought, but it continues to baffle me that at my age my parents were on their way to their third kid with a five-bedroom house and two relatively new cars on (mostly) just the income from an early-career staff member in a theater department at a small public university in north dakota

And now three decades later I'm an early-career employee of one of the top astronomy departments in the world and just proud of myself for affording an apartment barely large enough to keep my cats from getting anxious

I posted this on Reddit so why not also post here

This is from ~ June 2020 to last week in roughly equidistant steps
