PGC 18880 with SN 2012hr

[rogerg (Roger)]

Hi all,

An image of this SN of Peter's.

Even with 5 minute exposures on the ST8 I'm still not seeing the extent of the galaxy required to match it up with the SN! Sure must be in the far flung edges of the galaxy!

I suppose this was taken under moon lit skies, perahps that's the reason I'm not seeing these fainter extents of the galaxy.

I have colour data but am not good at LRGB processing (not something I do much of). I have tried but ended up with a washed out image which was hard to balance, so have stuck with the L.

10 x 300 second exposures
Unguided
12" SCT @ 2981mm (~f/10)
PME
ST8-XME @ bin 2x2, -15.

Regards,
Roger.

Nice shot Roger but which is the SN? I assume its the bright one at 12 o'clock. If it is, its v bright and miles form the spiral arms.

Great work there Roger. AAVSO now have an alert out on this supernova and are calling for photometry.
Pete, If you look at Martin Pughs (several hours exposure) image you can clearly see the faint outer arm in which SN2012hr is located.

Yep, I see the spiral arm now - it really is at the extremity of the galaxy.

Thanks for the image Roger - I plan to have a go when the clouds lift here in Sydney. Though I doubt I can manage as a clear an image as yours in 50 minutes

Sorry Pete, it would have been sensible for me to put lines to mark the SN, I should have done that.

Interesting. I'll make sure I continue to have it captured in my usual run of images.

Pete, my image isn't a scratch on Martin's so I'm sure you can get close to mine Taking the photo at a moonless time would be a good help.

Nice capture Roger.
