The following timelapses show, how much angular distance the comet 46/P Wirtanen makes, when closest to earth. From my data I see approximately a stunning 1° during 4 hours!
85mm photo lens with 1.5x crop sensor
93 exposures, each 60 seconds long (93 min total)
200mm photo lens with full frame sensor
160 exposures, each 90 seconds long (240 min total)
715mm/f7 APO with 1.5x crop sensor
71 exposures, 30 and 60 seconds over 80 min
Finally the full moon is over. The first chance to properly see some fainter objects like the comet 46/P Wirtanen. Comet 46/P Wirtanen started to rise more and more from the horizon. At November 10 the comet reached only 10° above the horizon. Now it is at approximately 20°. As for one day on November 28 the sticky clouds opened up above Austria. So I packed my gear and headed to the mountains. I ended up at a snow covered mountain top near Lachtal at 1857m a.s.l. At -8°C seeing, transparency and sky darknes were exceptionally! A really treat to observe 🙂
I set up my camera with a 85mm lens and captured 90 minutes of data until the moon rose. I chose the 85mm as I expected to see a tail extending from the comet. But as it seems, the tail is not extening sideways (seen from Earth) at the moment.
I am really pleased with the results and hope for another chance of good weather within the next few days…
I was eagerly waiting for the first chance to see the promising comet 46/P Wirtanen. As I was scheduled for a public viewing session at the local observatory, I set up my camera on the 50cm telescope after the last visitor left. Before slewing to the comet (which was still extremely low above the horizon), I wanted to try a few night time jewels: M27 (Dumbbell Nebula), core of M31 (Andromeda Galaxy) and M57 (Ring Nebula).
Afterwards I slewed the telescope to comet 46/P Wirtanen. The comet had risen to 10°. Weather was quite OK, but that low, there is a lot of bright haze. Visually I had no chance to see anything. So I tried to take a few shots and see, if I could process the results…
Well… unfortunately there is something mis-configured as I endet up with really huge stars in the range of 12 arcseconds. So there is not that much detail within the pictures as I would have expected. The comet is there and looks promising. But from the observatory location, it has to rise significantly above the horizon…
Here are the results:
