Please let me know which looks better on your monitor. I plan to post one or the other on the SBIG and LX200GPS news lists. Thanks, Joe Horsehead4: http://www.slas.us/gallery2/main.php?g2_itemId=6050&g2_imageViewsIndex=1 Horsehead3: http://www.slas.us/gallery2/main.php?g2_itemId=6054&g2_imageViewsIndex=1

Horsehead
by Joe Bauman 01 Nov '14

01 Nov '14

Just in time for Halloween, here's my astrophoto of the Headless Horseman's spectral horse. The Horsehead Nebula was the subject of about 4 1/2 hours of subexposures of l,r,g,b this morning at Lakeside, Tooele County. It was a serenely beautiful night, with stars just stunning and still air. But that air hit 27 degrees, putting ice in my plastic water bottle. Still, I had a great time. Thanks for taking a look -- Joe http://www.slas.us/gallery2/main.php?g2_itemId=6050&g2_imageViewsIndex=1

Patrick, I always mount my camera parallel with the telescope, that is at right angle to the handles -- as here http://www.slas.us/gallery2/main.php?g2_itemId=6057 -- and it tilts when the scope swings toward various targets like the Horeshead. Of course objects in space don't know up from down, so it doesn't matter how they're oriented in the picture. I don't try to fiddle with the camera so that north is up. Thanks for the compliment -- Joe ------------------------------ On Fri, Oct 31, 2014 4:41 PM MDT Wiggins Patrick wrote: >Both look very nice though 4 is a bit brighter so I'll go with that one. > >Plus both are rotated 90 degrees so that north is to the left and west is up. > >patrick > > >On 31 Oct 2014, at 12:53, Joe Bauman via Utah-Astronomy <utah-astronomy(a)mailman.xmission.com> wrote: > >> Please let me know which looks better on your monitor.

Probable supernova in M61
by Dale Hooper 31 Oct '14

31 Oct '14

I saw this mentioned yesterday on some other lists, but here is something with a bit more info so I thought I would send it along. It was mag 13.6 at discovery - so mainly a CCD object, but it is still brightening. http://www.universetoday.com/115818/possible-bright-supernova-lights-up-spi… Clear skies, Dale.

Re: [Utah-astronomy] 67P close up

Well, we can calculate the gravitational force. F=G*M1*M2/r^2 where G=6.67x10^11 N-m^2/kg^2, M1=Mass of object (kg), M2 = your mass (kg), r = radius (m). It is tough to get r because object is not a sphere and mass on opposite sides of us (if standing on the neck) would cancel out. It has a mass of 1.0x10^13 kg (wikipedia) and has dimensions of 4.1 x 4.5 km (wiki). Lets assume a sphere of radius 2 km just for fun. My mass is 82 kg (insignificant so ignored) F=G(1.0x10^13)/(2000^2)F= 0.0002 newtons <================= Err... kinda small. Even less if you stand on the neck and the mass on either side cancels out. Yes, the stated formula and constant are from memory.

Best image yet I've seen of 67P from Rosetta: http://blogs.esa.int/rosetta/files/2014/10/ESA_Rosetta_NAVCAM_141018_D.jpg Can't wait to see what the lander sees when it lands next month. patrick
