For those not aware and I'm probably one of the last to pick this up, there is a supernova near the centre of NGC 1566. When I noticed it I actually thought I had discovered something. It's the little star just to the right of the centre of the galaxy. For this shot I used 150 minutes of luminance taken last night and colour from an image taken several years ago.
ahh,I wasn't aware of that SN. Another nice galaxy, like NGC 1365 was with it's SN. In fact I often get NGC 1566 and NGC 1365 confused so it's funny that there's recent SN in both!
I have been considering Astrodon filters to replace my Astronomik TypeII and hopefully help my LRGB woes, but was just thinking I should do a direct comparison with someone else's LRGB attempts. Perhaps I'll use your image as a reference and see what similar exposures show up in an LRGB using my Astronomiks before splashing out on the Astrodons. This target with a SN seems like a reasonable excuse
Wasn't aware myself till I posted an image of Comet C/2012 K1 PanSTARRS with NGC 1566 in the field.
Kevin ( Comet Catcher) informed me there was SN visible.
Cheers,
Justin.
Thanks Justin. This one often gets your supernova blood pumping because of the prominent field star near the centre. I only noticed it because this time there were 2 stars.

I doubt whether you will notice much difference with the Astronomiks Roger. You might get less bright star halos with the Astrodons but other than that I think simple LRGB would look the same. Where the Astrodons are probably superior is in narrow band because of the small band pass.

Thanks Rick. I was going to get new RGB but with the usual crap weather I decided to use old data.

Ditto. 3nm NB Astrodons (and parfocal) are the go IMO, but for anything else perhaps not so important.
Very nice image Steve! Though I find myself drooling slightly at the resolution you have compared to the ASASSN-14ha image I took a couple of weeks ago My view of the galaxy was only worthy of the beginners astrophoto page, but you have bags of lovely detail in the arms there and lots of extension in the swirls of the arms. The SN looks to have faded a bit in that time, going from about the same brightness as the neighbouring star to noticeably dimmer in your image.
It's an interesting looking galaxy Steve. I can see a faint outer arm near the top of the image.
It's always been one of my favorites Paul. Back in the 1980s you were doing okay just getting the central regions. I think the outer arms were first imaged in detail by David Malin with his photo amplification process.
Very cool to capture a SN! Also a lovely image Steve!
Cheers, Marcus
Thanks Marcus. I almost discovered a SN in Centaurus A many years ago but didn't look at the image closely enough.

Thanks Mike. It's a lovely galaxy.

Great catch on the SN and a great job on the galaxy Steve!well done.
Thanks Louie

Thanks Greg. The colour is old data of course. The weather hasn't allowed me to get any new stuff. The SN therefor appears white whereas I believe it was showing up blue earlier.
