BOSS PSN50 in PGC18880

Martin Pugh · #1 20-12-2012, 06:16 PM

Hi folks
As most of you probably know, Peter Marples has discovered a PSN in PGC18880 in the constellation of Pictor. Once confirmed (and that s very close) this will be the 50th SN for BOSS and a personal 6th for Peter. So I was delighted to image this upon his request.

Actually, this is an early image as last nights heat and humidity basically meant I had to throw all of the colour data away. Things improved in the early hours so I kept the luminance.

So, right now this is LRGB consisting of 3 hours, and 45 minutes each RGB. Taken with the 12.5" RCOS and STL11K. I do plan to go significantly deeper on this and will update the image idc.

Congratulations to Peter and BOSS.

Cheers
Martin

Lovely image. The SN shows quite blue also.

Gemini doesn't have that much memory.

Hello and thanks everyone.

I am getting more data as I type - seeing better tonight.

According to The Sky, this galaxy has a magnitude of 12.7.

cheers
Martin

Martin, as I said in the sister thread to this one, this image is just beautiful, it's a real buzz seeing one of our discoveries in such a great portrait, thanks a bunch for your time to drop everything and do this for BOSS!
I would have imaged it in colour myself last night because we actually had good seeing without clouds until midnight, but i opted to image and check another 100 galaxies for SN No. 51 instead...pity i couldnt find it!

Nice capture & a top image in it's own right.

gregbradley · #14 21-12-2012, 09:34 AM

That's a pretty little galaxy. Its amazing how bright these supernovas are. Imagine if it were nearby.

Greg.

Thanks again folks.

Got another 5 hours last night on this, so a much improved image is on the way shortly.
cheers
Martin

Great photo and great capture Martin.

Nice image Martin.

What is the individual subframe exposure time for each of your luminance frames?

Martin Pugh · #18 25-12-2012, 09:41 PM

Thanks Ross/Roger.

this is a dim galaxy or what? My lum subs have been 20 minutes.

cheers
Martin
