First results with the new EQ Platform

[Mamsoth]

Finally got a chance to use my new Watchhouse EQ platform last night with my 12" Skyliner. Was terrified of balancing her on it but after a while I forgot the platform was even there!

Managed to get a few avis b4 the moon dipped behind the house...

First two are Tycho + surrounding area, second two are Plato crater and surrounding area and last is an unbarlowed view of the Southern limb, taken on 12/02/11.

Camera Atik 2-hs

12" Skywatcher

Revelation 2.5x Barlow

Around 300-500 frames stacked and processed in Registax

Also I've just had a look on my main PC and some of the pics look a little odd (especially the Plato ones) there's a checked effect as well as some odd straight lines. Whatever the cause is they aren't present when I open up the pictures in Registax so it can't be a problem with processing, does anyone have any ideas what could be the cause? Cheers and clear skies.
