Detected my first (previously known) Exoplanet!

Last night I detected my first (previously known) exoplanet! I did this by the tried-and-true transit method.

The exoplanet I chose is called WASP-19b, it is located around 880 LY away in the constellation Vela. It is a Jupiter-sized planet with an orbital period (year) of less than 19 earth-hours!

Definitely room for improvement of the data quality, would probably better to have a higher focal length than my current 420mm. Still very happy, didn't know whether it would work at all, I was overjoyed when I plotted the data and saw the dip!

Multi-aperture photometry measurements made in AstroImage J, and model fitting performed on Exoplanet Transit Database online light curve model-fitting tool.

Equipment:
SharpStar HNTF2.8 420mm
ASI183MM-Pro
NEQ6 Pro
Optolong Luminance filter

Exposures:
300*30s (gain: 50),-15C, bin1x1
L filter

Amazing - who would have thought you could be detecting interstellar planets from your backyard?

Congratulations

Just wondering, should this image be posted in the "planetary" section, or the one for DSO's?

Thanks a lot everyone! I was genuinely surprised it worked first try!

Granted the data quality could absolutely be improved, but that's something I'll work on the more I do this

Just Amazing that amateurs can now do this kind of research .

Stefan,


Nice result, even with the noisy data it looks real to me. With regards to the focal length I don't think it would improve things as you are only measuring changes in brightness and that is unlikely to be different with a longer focal length. All these measurements are going to be limited by the atmosphere.

Was wondering how feasible this was for amateurs. Awesome work!!
