I'd recommend https://www.lightpollutionmap.info/ to find a good dark sky

Re: [darktable-user] Comet NEOWISE

[Niranjan Rao]

I have Canon sx60hs. It doesn't have detachable lens.

I am in completely urban environment. Because of weather, ambient light 
and buildings in between, I was not able to see the comet yet.


Planning to make a trip litter further where there should be little more 
dark and hopefully better weather.



Thanks,

Aperture priority will get confused with the dark sky and would 
likely overexpose the comet.


Sadly I am in Australia and can not see this comet. Maybe in another
