How to image a comet by mistake

Comet 41P/Tuttle-Giacobini-Kresak

Was trying to find a galaxy in Ursa Major I fancied doing on Friday at astro camp, and the GOTO did not find it, so I slewed around a bit and found a fuzzy, which was smaller than I expected but thought "that must be it".

The following day I examined my subs and I was surprised to find the "galaxy" had moved and was elongated in the the 600secs subs. Duh, it was actually a comet.

So decided to turn it into an animation, though having imaged it with a mono camera in LRBG it is only in B&W.
600sec luminance subs and 300sec binned RGB subs so image quality and shape of comet is variable.

Apparently it has no tail.
