IC-1795 Narrow Band

"I have lots of data to do that study... but here is how it works: once you are calibrated so that the only noise sources are read noise and photon shot noise, you improve the SNR by a factor of two for every quadrupling of data you take.... it is…"

this is work in progress. I keep getting asked questions by users as to what camera they should buy. Of course there's no single answer.



so I am preparing a monograph to examine the various factors involved in sensors and cameras appropriate for use in astro-imaging (and other imaging as well).



the first section of the work is in a pre-release form but may be useful for discussion so I am posting it here today.



The idea is to add to this work each week and to… Continue

Clear Skies!

Conor.
