This scope will really become useful after TeleVue releases
their new Paracorr (made to work down to F/2.5, and will
work with longer F/Ratios). I still have coma issues with
the current version.
Anyhow, I took 8x8m last night of NGC6888 at F/4.6 using
the universal paracorr and a modded Canon XS at ISO1600
with the Lumicon Deep Sky filter. This is full frame
reduced to group size. There is a coma issue in the upper
left of the frame.

Here is a cropped version (still reduced) to show more
detail in the nebula.

Super smooth and very detailed.
The coma does show a bit even in the crop but its pretty minor and this is a tough one to get looking that good so nice work.
