Which sampling rate (South East England) ?

[vincentnm]

Hi All,

I am trying to choose a CCD camera. One of the factors is the sampling rate I should aim for.

Arc seconds per Pixel (Sampling) = 206 * pixel size in microns / focal length in mm

Ok, so I can calculate the sampling rate for various CCD camera's out in the market for my scope. How do I know what is the optimal sampling rate that my sky conditions will allow in SouthEast England? And does the target type matter? Bright galaxies can be undersampled? Narrowband imaging of nebulae requires over sampling?

Read in Ron Wodaski's book, sky conditions allow for a sampling rate between 2 and 4 arc seconds per pixel. What is the typical value for UK skies?

A few examples, these are the resolutions I can get for my 400 mm hyperstar:

QHY8Pro - 4.02 "/pixel

Starlight Xpress H16 - 3.82 "/pixel

Starlight Xpress M8C - 1.61 "/pixel

Thanks,

Vincent.
