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. |
