Smart Historgram and filters

Post by ColinR » Mon Aug 12, 2019 10:14 am

I feel that this is a bit of a daft question, but here I go anyway.
I am assuming that filters, (CLS, Narrow Band etc) are fitted prior to invoking the Smart Histogram/Brain function and that therefore the effect of any filter is included in the final calculation/graph?

Thanks in advance.

Hi,

Yes, absolutely right. You need to fit the filter before you measure the sky brightness using the brain as a light pollution filter will definitely reduce the sky brightness and lead to longer sub exposure times being calculated.

There's no need to worry about having a filter or not if you do the sensor analysis procedure – you can do it with filters, without filters, whichever way you choose and it won't make any significant difference to the results.

Cheers, Robin
