Comet Catalina charging into galaxies - timelapse

Once again, spontaneously on the day, I went to the same b&b edge of the Kent Downs last week Tuesday (same time Mike snapped that fun Moon in Hyades picture) to capitalise on what looked to be another rare clear night.

This time I took my 8" SCT as I noticed on stellarium that comet catalina will pass through a very interesting system of galaxies called the Keenan System.  A fascinating galaxy that actually has a "bridge" between the galaxies!  Its not like the Whirpool galaxy which is merging, the Keenan's system in comparison is quite stable looking and independant of each other apart from the connecting bridge.

A nice APOD picture of it in 2008:

Sadly, my telescope is just not powerful enough to discern that "bridge" 🙁  It seems you need a 12" or more to see that feature.  So those of you that have larger telescopes, please have a look at that system and let us know what you see!  I hope I can look through a large telescope and see it myself one day.

Anyhow, besides that disappointment, I took a timelapse set of images on the comet's journey (man, it really does move quickly).  The timelapse is 7-8 seconds but the real time duration was 2hrs 14mins.   Because my intention was to make a timelapse, I set the ISO very high at 6400 so the galaxies can show up more clearly in each frame....so hence the noise which I am sorry about.

I actually tried to stack them too but its really difficult to stack the comet without star trails, reducing the noise without losing details on the galaxies...really hard!  So I give up, lol.

Anyway, here's the timelaspe...oh forgot to also mention that at the beginning of the timelapse, the moon was up and near full, so the sky is very blue due to the moonlight pollution but once the moon set, the sky became darker and so those galaxies punched out more.
