I was curious to see whether I could observe an exoplanet transit using fairly moderate equipment and I have to say this has been a really fun thing to try. Yes, there is a bit of learning involved and I still have a long way to go, but definitely within the capability of anyone who is doing deep sky imaging.
There are some very good resources on line from the likes of Dr Dennis Conti who has produced an excellent guide.
So, a couple of weeks ago I established that it was possible for my set up to do this. I am using an ASI 178MM with an 8"SCT on a EQ6-R Pro all controlled by ASIAIR PRO. During that first session I only managed to capture the second half of the transit due to various user errors and not being on the right target star. For the second attempt I had a good clear night and selected a target star that would be fully visible from my location. I took just under 400 light frames (Science images) at 30 sec exposure with a 10 sec gap. It is important to take darks, flats and bias as you must calibrate the images. I used Astroimagej to do the differential photometry. The videos produced by the RASCANADA are a really useful resource to help understand the whole process.
Now, before you rush off to use your ASIAIR PRO to do this, there is currently a small bug that is preventing Astroimagej opening the light frames https://bbs.astronomy-imaging-camera.com/d/12070-fits-header-astroimagej-issue ZWO have said they will address this in the next update and I'm sure they will solve it. It has meant me manually adjusting 400 Fits headers!
The attached measurements show the dip in the light curve that corelates very nicely with the predictions. I can tell you there was a big smile on my face when the light curve popped out as AIJ plots it. I think it is amazing that we can now have a go at this, even with relatively low cost cameras and small telescopes.
Give it a go. Its a lot of fun :
