Thanks Guys,

Frank..I would say its more bad processing then anything

Jim,

yes the STL is a nice camera but it's far from top of the range...probably closer to bottom of the range specialy in QE sensativity...your paying more for the size of the chip being 35mm format

Regarding a focal reducer..its not that easy...if I used the Meade 6.3 fr I would loose more then half the image due to severe vignetting the 3.3 would be unuseable for these chips.

I tried the Lumicon FR which has a 80mm focal reducer at F7 last night....thats about as good as it gets in large format focal reducers and with that I still lost a lot FOV...below is a pic of the fov I lose with an 80mm Diameter FR..imagine what would be lost using a Meade 48mm fr.
