Re: [APML] Catpaw from HK

Hi,

Thanks!

I didn't apply any special processing techniques. I
just chose the night with the best transparency and
exposed up to the sky fog limit that my site allows. I
guess the flat-field processing takes care of the
rest. 

Sky90 is the Takahashi FCL90. But I used the reducer
so the f-ratio 4.5.

Cheers,
Paul
