General Photometry Question for Beginners

Hi All,

Im interested in getting into photometry.  Ive read the CCD manual and have a decent foundation in the basics.   At this point my interests lie in making as precise and accurate measurements as possible.  Not interested in analysis or anything else, only data submission.  I have no preference of what variables I would like to observe. What ever would best fit my equipment and time limitations, and best for making the most scientifically useful data.  My questions are:

1) Is there alot of submissions that are not "good data" submissions.  If so, how is the "good data" differentiated from bad?  

2)  Im sure there is many submissions not transformed, and other bad techniques used in data collection causing many "bad" data submissions.  Are there standards that should be upheld or rankings used, example: B_V is a minimum?  

3)  What would be the variables to observe to submit really "good" data.  I dont mind boring, for example observing a single LPV all night to be able to get good averages and stats.  Also considering I might be limited two 4-5 nights a month.  


My equipment is:  CGEM45, C8, StarlightXpress H35


Thanks in advance for all your help

Averaging or stacking is good.

Good hunting and have fun.
