Good evening ladies and gentlemen! Do you remember the star exploded in the Pinwheel galaxy last year? I blogged my observation five months ago at http://xipteras.blogspot.com and since many people found that thread interesting I decided to revisit that galaxy again to find out how the supernova SN2011fe now looks like. From the beginning, it was clear for me, I had to use a bigger instrument than last year and a sensitive astrocamera exposing for a long time since the supernova remnant should be remarkably fainter now than last year. This time, I had to go really deep, so I made 7 sub exposures with 15 minutes each at 704mm focal length (f/5.4). I stacked and processed the sub exposures with special software to make it happen. Here is the galaxy M101 and the area around it. There is only one question now: "Can we still see the supernova remnant five months later?"
The answer is "Yes, we can!" See below:
"The Pinwheel Galaxy (also known as Messier 101 or NGC 5457) is a face-on spiral galaxy in the constellation Ursa Major." [Source: Wikipedia]
