Hi.

I have just finished modifying my 1000D. Replacing the factory filter with an Astrodon Inside filter bought from Hap Griffin.

Following Gary Honis' instructions was straight forward enough - getting the job done without too much trouble.

I took a few quick flats. One of which is posted below. It is quite different to previous flats taken with this camera because of the new filter. But to me it looks a bit odd. Could it be representative of the filter coating?

I've added a grey scale (oops inverted) of the same flat for comparison - which looks OK to me.

Many thanks

Rowland.
