         I will keep this graph updated by getting at least one image a night (weather permitting) till it is no longer visible.
 Note: The smaller the magnitude number the brighter the object.

     If you  are interested in how to convert ADU ( Analog Digital Units) values to  a Magnitude value, check out this link http://www.warren-wilson.edu/~physics/Contemp-Astronomy/starmag/starmag.html. You  will need the ADU and Magnitude numbers for a reference star  in the same field as the primary object as well as the ADU value of the object in question.  I use Nebulosity to get the ADU figures.

These measurements were taken in the visible light without any color filters using an Orion SSP V2 on a SN8 at 5 minute exposure dark subtracted and flat applied.

 

These images will be updated as I get more data.
