@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
