Thanks guys for the comments I will try to answer the questions.
Josh no dew on the primary. Too much mass for that.
Brett that is just what I am looking for, I will be perfect I have a mount hub pro to control the heat.
Naskies, yes it is very much the same but some issues have been sorted. The 12 does not have baffling to the tube though.
Mark I would consider getting the tube myself.
G-day putting a dew shield on it is a bit impractical. My goal is to have it work remotely and putting a dew shield on it which is likely to be had made will present issues with closing the roof even in the side ways point home position. So yes the dew shield is obtainable, but my thoughts were practicality.
First image.
This image is a stack of 5 images with attrocious guiding. The maxim graph was beset with triangles over the entire depth of the graph. At times the guiding was plus or minus 4 pixels.
I tried a lot of guide parameters but would like any advice using the STL11 internal chip guider and what settings are best given my focal length of 2400mm.
That said pointing was pretty good but I need to do some collimating and am considering getting a Tak collimating scope.
The image looks way better at this scale rather than larger.
