How my opinion has changed over the last year about ISO sttings.

I used to always think I got better results with the higher iso but in fact is better with lower ISO's longer exposures.

The point is even when you image at the lower ISO's yes your first impresion of each exposure does have less detail visualy but its just hidden and you can then bring out more detail through processing due to less noise.

Highest ISO I will ever use will be 800 and will use ISO400 the most...I may up the ISO only for HA imaging due to the high light blocking ability of the HA filter.

Still a nice image Scott even with the noise.

Well that my opinion.
