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 know DSLRs are more for “official” AP imaging and I should probably stick with my trusty ASI224 or maybe think about a 294 or similar sensors but....as probably many, I have a DSLR sitting at home not doing much. Can I do EAA with it?
Today is quite easy to have 24Mp in relativity cheap bodies so why not to use it somehow? Small pixels..I know, but maybe going for wide field and bright objects with fast lenses it may still work and give something interesting. Anyone tried? Any experience?
What I really like of EAA is the ability to do everything while observing and without the need to come back for long processing sessions. I have searched around a bit but I can’t find a stacking software like Sharpcap for DSLR doing live viewing as well as stacking. I think I could somehow save each frame in a folder and then stack them with DSS (if I got the name right) but can I then control remotely the camera, exposition and have live preview when slewing around?
Just interested to know if anyone know more about this or more in general discuss about DSLR and EAA.
