Here's another shot of M77 showing the supernova. I haven't marked it but it's just to the right of the central bright region. This was only a short exposure and I may follow up with more data tonight if the weather holds.

Cheers

Steve

Superb result. Lots of excellent detail there.

Feeling in a miserable mood for other reasons, then thought about the effect of a supernova on the locals. Perhaps with a type II supernova there are no locals anyway.

Either way, your image helped put things in perspective.

Thanks M&T. Hope you're tot feeling miserable anymore. I feel very miserable around Christmas. Not one of my favourite times of the year.



Thanks Marc

Thanks Colin. I'm hoping to improve on it with some more data but we'll see.

Thanks Kevin. Don't delay too long because I think the supernova is getting fainter.

Yikes. I've got rain soon too. What magnitude is it at the moment? It looks pretty faint already.

Thanks Peter. I got some reasonably good luminance last night and hope to get some Ha tonight so the best version maybe yet to come.

I think it's about 13.6 at the moment. This website has some details:

Like I said on FB, a month ago I was considering doing an extended run on this target. It is logged into my imaging panel on CCDAP and I was thinking I should really image this target. I decided after some searching around that I would undertake another target which was at a better declination. I suspect by doing this I have missed the chance of a discovery. Sometimes you have to go on your gut instincts. This is a nice rendering of a tough target Steve. Well done.

Thanks Paul. I haven't finished with it yet. I'm going to try some Ha tonight. I only found out about the supernova via a UK colleague.

Thanks. I'm going to see how it looks with a bit of Ha tonight.

Looks great, Steve. Look forward to the addition of Ha!

Well it's clear at the moment so we'l see
