I had a break in the clouds for just one hour tonight, so I snagged Supernovae 2016cok in M66.  I only had a chance to shoot the Luminescence data before the clouds rolled in, however.  Thirteen subs at 300 seconds each.  Flats, darks and Bias frames added. 

I added a bit of Hubble data in the color channel.  If it's better to just post a monochrome version, I'll gladly do that.  It also appears that I captured and asteroid in the field as well? What do you think?

It's your picture. Personally, when I shoot a monochrome, I post monochrome. :) I am kind of amazed why so many think that astronomical images must always be in color. Most actually aren't.

Yeah, I debated it for a few minutes.  Only the galaxy itself is colored, not the stars. Here's the mono version:

Nice catch. Did you do any digging to see what asteroid that is?

Wes:  I did only a cursory search but didn't find any information about it.  Using Blink in PI you can clearly track the object frame by frame.  It's surprisingly bright!  Perhaps others more knowledgeable on where to look might come across something?

What time was it exactly? Maybe I can take a stab at it...

I think there's a good possibility that it's asteroid (28) Bellona. It was in that exact area for several hours and is fairly bright. It's mag 11 and is 121km in diameter. 

 

Awesome. ;)

 

 

If you notice in my screen capture, you actually caught another, fainter asteroid, 19th mag as well!

Wes, that's probably it.  First image was taken at 11:53pm EST through 12:56EST.

 

Did you find that with a Skyweek App?

I managed to collect 5-minutes of data on Supernova 2016cok in Messier 66 (Leo) last evening, June 1, 2016 before the clouds rolled in.  I place the magnitude at approximately 16.4 simply based on comparison to other stars in the field of view.  The 5-minute stacked image was using 15-second subs at ISO 5000. Equipment included a Canon 6D, Antares Focal Reducer and Meade 12” LX90 telescope.
