Only had 15 minutes last night
With the astro as I had company
Tonight its cloudy again.
The astro Optical was tack sharp
On jupiter and then viewed orion
All stars looked great ...pinpoint
Round...only went to a 12 mm ep.
Typical royal astro.
Next few days don't look good
So ill work on my woodshop
Till I can set zeiss up.
Im getting antsy ...

that scope looks great on the astro physics mount.
optics were no surprise.
had to break it down early as i get up at 4am.
did a star test and see no color and nice rings in and out.
took it up to 300 on Jupiter even though seeing was about
8 out of 10...real high thin clouds just before dark
but the Zeiss did real well anyway.
stars in Orion were pinpoint.
i am thinking i need to make a 4" stop for the superplanetary and have myself a little shootout.
i think the winner will be.....
dont really know but i need to get out for a few hours
and do some clusters and double stars...and of course
view the moon.

i think I saw something on the early christen triplets and it was stated that even the F8 scope performed similar to a F20 scope or longer scope. So I would presume that an 6" F12 stopped down to 4" would be some figure that I would need a calculator to figure out.

an 6" F12 stopped down to 4" would be some figure
Color control would be comparable to that of a 4" at F/18. Not quite apochromatic, but quite good.
