Will this setup work for backyard photometry?

I've been looking for a way to do photometry cheaply (variables and standards). I have no interest in eyepiece observations of the night sky or astrophotography.

I am currently considering purchasing this: http://www.telescope.com/Telescopes...graph-Telescope/pc/1/c/11/sc/345/p/113911.uts

to attach to my already purchased this: https://www.usa.canon.com/internet/...owershot-sx510-hs?selectedName=Specifications.

Of course the f-ratio is too slow and the camera garbage, but I was hoping someone with experience tinkering might be able to give me an idea of how this could perform for collecting raw images to get reduced/analyzed.

Simple answer is yes but not ideal. Have a look at the aavso web site.

That setup should work just fine. Differential photometry with nearly any camera and telescope is easily capable of getting centi to millimag accuracy with perhaps a few minutes of exposure time. I've done photometry accurate enough to detect the transit of Exoplanet TrES-3b across its star, where the 30 second to 2 minute sub-exposures have to have about 0.01 mag accuracy, using a CCD and an 8-inch scope, so you should do just fine with your equipment given that you can integrate many more exposures than I could.

Great, that's exciting thanks.
