CBAT Notes

      So what's the difference between a NOVA and a SUPERNOVA?

Supernovae are catastrophic destructive events caused by a core collapse of a star.
A Classic Nova is  the result of fusion reaction  in the outer layer of a white dwarf star which is slowly stealing material from it neighbor star. If the amount of mass accreted reaches a critical point the white dwarf will explode in a  type I-a supernova.
A nova can occur  repeatedly in the same star.

A listing of Supernovae brighter than 17 Mag. can be found at this site

         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, dark subtracted and flat applied.


These images will be updated as I get more data.
