Comet C/20009 P1 Garrad Septmeber 18
Comet C/2009 P1 Garrad imaged using the GRAS-05 instrument (compare with this June 29 image from GRAS-05). Click to embiggen.1 x 120 sec red, green and blue filter exposures stretched with FITS liberator then assembled into an RGB composite using the GIMP (I usually use ImageJ, but I'm trying a different approach this time). This is illustrated with the image below:
My image from August 26 taken with the Global-Rent-a-Scope G-14 instrument (1 x 120 sec red, green and blue filter exposures stretched with FITS liberator then assembled into an RGB composite using the GIMP, click to embiggen) compare this with the same image stretched with FITS liberator then assembled into an RGB composite using ImageJ.Labels: astrophotography, comet, Global Rent-a-Scope

Hello Mr. Musgrave
One question: say the asteroid 2007 TD is dangerous, come to about 6.2 LD
http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2007%20TD;orb=1
what think?.
I await your response in this means.

This small asteroid is no threat at all, it comes no closer than 6 times the distance of the Earth to the Moon, which is very far away.
Hi Mr. Musgrave,
How's things down under?
I am located in southern Finland and I was looking the net the find the trajectory of comet garradd, but I didnt find nothing specific (all links vague and ambigious). Can you point me in the good direction?
I would like the trajectory of the comet.
Thanks and by the way really nice picture (the first and the second). Second is not as large as the first one (pict. dimension)
Cheers,
Tapani Isomäki
