I was looking to get into astrophotography with my 10 inch dobson and for start would like to buy something affordable. Cameras can be used or new. Thanks in advance!

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.

Hi All I’m considering purchasing an 8”aperture, f3.8 newtonian ( primarily for EAA) from Orion UK and would appreciate any input or feedback from anyone familiar with the product, the company or the purchasing process - and how to assess the compatibility with my current cameras.
This is would be a step up from my current equipment and entails selecting components that I’ve never used and know little about such as a rack and pinion focuser and components (ACU-3L), and coma corrector (Wynne Corrector). I’ve added links to these items below. I’m also feeling unsure of how to mate up my Zwo 178 and 294 cameras to the 3” focuser and whether there will be an acceptable match between the scope optics and my sensors.
I’m sure the folks at Orion UK will assist with all this but I’d sure welcome input from the Stargazer's Lounge community before starting the dialog with Orion UK.
thank you in advance for any help you can provide!

Hi everyone,
I'm trying to figure out the cause of these weird star shapes I'm getting with my 130pds. I had them before, but someone narrowed it down to being pinched optics. So I loosened the primary retention clips, which seemed to fix the problem. Now that I've been able to get back out for another night of imaging, they seem to be back again! I made sure that the primary retention clips are still loose - should they be touching the mirror or not? I've also made sure that the primary collimation locking screws aren't done up too tight as well. Collimation through my cheshire looks to be spot on to me. Here's my image of Andromeda with the odd stars in question:
