NGC6753 new Supernova

[PeterM]

You may have seen this in the Celestial and Astronomical Events posts but if not thought would post here as this will be a really nice target for a colour image.
Now officially classified as a new Supernova it is well placed for imaging.
Good luck would love to see this is in colour.

Thanks folks.

Humm...ran 30 minutes on it just now. Not sure I want to do colour
(a rather small, unremarkable galaxy )

So which one is the SN?

P.S.
Sorry, so far I only have NB flats on the AstroDon's so the calibration/background is a little ropey

Hi Peter,

Thanks for having a go. Looks a pretty pic to me.

Small, well yes at 150 million light years away when compared to the multitude of massive Messier Objects we are used to. Unremarkable, not really. It now sports it's 3rd Supernova in less than 20 years, that transient object may last a month or so until it fades away. So at the moment it's a target of opportunity for those who may want to try and give it a go.

You pose an interesting question "so which one is the SN?"

In taking images of galaxies there maybe a chance (albeit slight) that you could find a bright transient object in your image, possibly being a Supernova, even a known/unknown Minor Planet or Variable star. But how would you know and why bother checking anyways? Seems to me going to go to all those hours of collecting data to get that fine galaxy image, then it's not that much more effort involved to have a quick look for anything not supposed to be there. And yes if it's in a large, close by galaxy, then a discovery could make the the effort even more rewarding and satisfying. May even be of some real science value.

I have attached an image from the Digitised Sky Survey, so will let you make your own discovery in your image.
You may even want to post it to David Bishop's Bright Supernova Page, particularly if you do try for colour, always welcomed.

Also below are several useful links worth having - The Digitised Sky Survey Images, a link to The Minor Planet Checker and to the General Catalogue Of Variable Stars (GCVS).

Hi Peter

Got this from the Astrofest.

8" f4, stacked 27 x 60secs with a SBIG 8300C.
A new scope, unfortunately did have time to get a coma corrector / field flattener.

Had problems with PHD so was limited to 60 second subs.

The first image shows the entire field.
The second image is cropped to show the galaxy.

Well that certainly shows the SN well and with colour! Well done.
You got an image of this galaxy for Bob Evans SN2000cj but I can't get it to load on the BSP?
Getting a bit of interest from some professional astronomers now who may see if they can identify the progenitor in the remarkable Hubble images and data.
Just never know where it goes really.

Well I did offer

I heard about it, and even imaged NGC6744 in same constellation, not realising just nearby was this. Probably wouldn't have done it justice with my 506mm FL refractor anyway.
