[Aavso-photometry] New Guy...starting out with ILAqr

[mlfleenor at charter.net]

Hello,

I am a brand new AAVSO member and thought I'd start out with the ILAqr campaign. I am currently using an ST10XME/Tak FSQ106 and a Schuler "V" filter for my photometric setup. I have been shooting pretty pictures for several years now from my often cloudy suburban location in Knoxville,TN. I have very limited experience with photometry doing some unfiltered CV work in the past but I am interested in transit observations of potential exoplanet harboring stars.  

I have a question as I am in the middle of a run right now. Is it recommended to re-check focus during an exposure sequence? I am setup with robo-focus and with CCD Autopilot I usually re-check focus automatically every hour to ensure thermal contraction of the ota hasn't ruined my focus.

Thanks,

Mike
