Thanks Alpal - but actually I used the inbuilt guider chip in the STL-11000M for this. I'm still tweaking the scope to facilitate the use of the guidescope for at least the RGB frames, but it is quite challenging to maintain pixel level consistency between the two optical systems. I did do a test the other evening in which I used the guidescope for a 20min sub with no star elongation which is encouraging, but I need to try different declination / elevations, etc before I can say how true that is across the sky.

Hi David,
Thanks for the update -
I could only find mention in your article about a guide scope.
Good luck with different parts of the sky.
From a quick read of the article it looks like you've
sorted out any flexure - it is possible to do.
When I tried with my older setup without an OAG
I wasn't getting consistent subframes & one night had to delete half of them.
I found that pointing North was great but anywhere South was bad.
My TS9 OAG was short enough to solve the problem with it's short 9mm back focus.
I am looking forward to some colour images from your system
- they should be real eye candy.
cheers
Allan
