Thanks for the reply Fred.

to be honest I could use 7 second images, but each image looks so noisey from the 20 second that I just did not think it would help the plate solves. Next run I will give it a go. Yes the hit miss ratio is quite high. I am using the QSI as the imager and I would have thought it would be fine. Interestingly I have to use the TSA to image with as the GSO could not plate solve at all. I put this down to the notion that the scope is probably not an f8 as reported and this affects the scale all the time.

The map is spread all over the sky from 40 degrees up to 80.

I was going to use Tpoint Mapper and had it installed but I had to pay for Pin point for that system to operate (at least I think this is what is required). I don't think there is a problem with the operation of CCDsoft, The Sky6, Tpoint and AutomapperII. So given I just paid for CCDsoft I would not be keen to use Tpoint Mapper.

I am also wondering if my image scale is not 100% correct. I am using the flattener also and I think that affects the focal length by 2mm. I will need to look this up to find out for sure.

Do you think the fit model data looks odd Fred? What are your thoughts on the RMS figure? Un adjusted everything is way of to the right. I suspect it is time related. I am using internet update and that could well be a problem too. I would welcome your thoughts on that issue. The modelling I can live with, but not getting good pointing is bothering me.

edit. sorry the flattener makes it 800mm for the TSA and that means a significant difference. I will try that tomorrow night.
