Hi Rolando,

> Nice work! Do you send your results to any organizations?


There is an active database which keeps track of all such results for

further analysis and study. Such results are especially important for

confirmation of published results and trend analysis (ex. decaying

exoplanet orbits). This database will be assumed by CalTech shortly

since they are finalizing their data format for result submissions.

This winter is proving to be very difficult for imaging yet again. I had

a couple of clear nights with incredible transparency (and freezing

temperatures) but the seeing was horrific (FWHM > 6"). Just to give you

an idea, I was not able to focus. Such nights are perfect for exoplanet

work since we are interested in the flux and, as such, things such as

good seeing and perfect focus are not an issue. In fact, it is best to

slightly defocus so as to spread the photons amongst greater pixels,

thus allowing greater length exposures without saturation and which in

turn means better S/N. Since we are dealing with fractions of a

magnitude during an exoplanet transit (6-25 parts per thousand), really

good S/N is the key to success.

Anyway, my beloved AP160 has now tackled 22 separate exoplanets and we

have a few more to go before we exhaust the list. We also now have the

five new finds from the Kepler mission and which will be prime during

the summer since they lie in Cygnus and Draco.
