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.
The Knowle Astronomical Society is holding a
PUBLIC STARGAZING & BEGINNERS EVENING
On Monday 7th October 2019 at 8pm at
Dorridge Village Hall, Grange Road, B93 8QA
If the weather isn't favourable (what are the chances?) we will set up a few 'scopes in the hall to show people and we will also be giving a beginners talk in the hall and, who knows, maybe we'll recruit a few new members. Light refreshments will be available throughout the evening.
Sharing with you my best images of Jupiter and Saturn for this year.
I haven't had the luck of a High Pressure system with no wind speed yet, but on the 17th it was as close as I had for planetary this Jupiter/Saturn season.
Not my best images of the gas giants ever but ok IMO.
I'm happy to see that the GRS seems to be repairing itself, last time I imaged Jupiter, the border around the GRS looked like it was breaking up so perhaps it'll be around long enough for my kids to see in the eyepiece.
Captured at f33. Images consist of the best 15% frames from 13x60sec @ 60fps for Jupiter and 13x120s @ 30fps for Saturn, derotated in WinJupos.
