Prolly a stupid question but...

[toc]

If I am using software like SGP and am platesolving, is there any benefit in having sophisticated sky modelling? I guess it just means that initial target will be closer to correct before plate-solving kicks in?

I don't think so. I use SGP and EQMOD and don't bother with a sky model at all any more. Plate solving takes care of it all.

I agree you don't need sky modelling when you have plate solve and sync.
Unless you are silly enough to image unguided and then a good sky model can help.

I don't even bother with a star alignment when I first switch on, I just go straight from park to the target, then plate solve and sync, another goto command then puts the target dead centre.
