ccd imagen y medición

Anoche tomé una imagen de SN2016cok en M66; la medición me dío 16.33ª en V Johnson con la referencia fotométrica de la carta reportada por Francisco Violat-Bordonau.

Quisiera aprovechar la ocasión para volver a contactar con Francisco, saber donde anda y que hace y mandarle recuerdos de Teófilo. Tengo el mismo correo que entonces; si te apetece contactar hazlo al correo teoarranz@yahoo.es.

SN 2016cok

I got a few B & V images a few nights ago (Planewave CDK-17, Astrodon BVRI), but photometry on this one will be tough -- lots of background light from the host galaxy.

I could plate solve a "before" image from a few months back and the new images so I could accurately place the aperture in each and try to subtract the background light -- is there an accepted method for doing this?

 

  I certainly don't have a high degree of confidence in any measures that don't do something to compensate for the galaxy background.

 

Clear skies,

Subtracting pre event Galaxy

Hello Brad

I have never tried this, but I think the accepted proceedure is to get a pre event image and scale it properly and subtract it from the SN image, then do PT.  I guess properly scaling the pre event image means making it so that all the galaxy disappears in the subtraction.  Sounds easy, probably is hard--sounds like fun.

I got 10 images apiece in BVIC at around 10:00 pm Daylight Mountian Time. Can't do the photometry until I can shoot some flats.  Can't shoot some flats until the weather clears! I am tempted to rebuild the flats box I used to have. Natural light flats are better but what a hassle! My computer tanked when I was trying to get flats and by the time I had it fixed it was already to late. However, here is one of the V images. Sixty seconds and processed with unsharp masked and digital development. Celstron 11" CPC at F\6.3. The seeing was not the best but it was the first clear night in a month. This was a "tourist" image I made for some non-technical friends, thus the big white arrow!
