Description

Went for a number of comets on April 1st - 2nd.  After 12P/Pons-Brooks, my second target was 10th magnitude comet 13P/ Olbers, seen here.  Also setting in the western evening skies I salvaged 10 x 120 seconds of this comet to stack for this image.  After seeing Taras' image multiple days later, same comet,  where a plasma tail was clearly visible I pushed my 20 minutes of exposure time to the extreme.  The molted background is a result of the overstretched image and some hints of tail dynamics appears (however so slightly).  This image is highly cropped due to the full frame's super wide field of view which I found unnecessary to save.
