We are running a session at my local society on transits and occultations. One station will focus on exoplanet transits, and we'd like to build a very simple model to demonstrate this. We have a star (light source) and an orbiting "planet" but I need to work out how to detect the changes in light intensity and display this on a laptop, like a classical transit photometry trace below (taken from https://heasarc.gsfc.nasa.gov/docs/tess/primary-science.html).
Is there a way to take a feed from a DSLR through the USB output to do this, else I could get an adapter for my ZWO and put an EOS lens on the front of that. I really do want a light intensity vs time trace in real time on the laptop. This model will be run in a darkened room.
Thanks for any comments.
Hiya, have absolutely no idea where to begin finding a camera for Astrophotography. And by that I mean - I know I want a canon but am unsure which to buy. It will be a second hand one. Does it need to be full frame ? Can any and all models be modified ? Is a higher pixel count the way to go ? What are the important things to look for in a DSLR ?
any help would be great.
Back in early Feb I tried imaging Markarian's Chain, but after 2 subs I encountered guiding issues (a first for me) so had to give up.
So just for kicks and giggles, I decided to process them! ?
So this is 2 x 10mins. With the D5300, 80ED and HEQ5-Pro. 'Stacked' (if it's even right to use that term!) in APP, and processed in PS. Then reduced to 75% for posting.
Why oh why oh why..... I honestly don't even know myself ?
I'm breaking the cardinal rule here of posting late at night, right after finishing PP, so let's see what sense the dawn brings! ?
I shot this in the early hrs of 29th of March. There was no moon present (i think!) and conditions were pretty good, AFAIK.
This is 28 x 360s, so about 2.75 hrs in total. Taken as usual with the D5300, IDAS-D1, and SW 80ED.
APP used for stacking and gradient reduction, everything else done in PS.
Would have liked twice, or 3 times, the data, but it's just not happening, so i've just decided to process what i've got.
Thanks for looking, and all CC welcome as always ?
