Take me to the stars -- asking for directions & getting good answers

The setup you see here in action : /stargazer95050/28667577

To understand how it all works and links to the (free) tools, read this blog entry : www.ipernity.com/blog/stargazer95050/636937

What happens here is a useful combination of SW tools with telescope mount & on-board cameras, that helps me to accurately get where I want to go.
1) I select the target -- various (sky chart) programs can do that. Even the telescope's hand-controller does that
2) The telescope slews to the given coordinates -- nothing special here if you have a GOTO-mount
3) I task AstroTortilla with checking & correcting the position
4) the IMAGING-camera takes a look at the sky -- I use high ISO settings to avoid startrails & accelerate movements
5) The image is converted and transferred to the astrometry solver
6) results are parsed, ACTUAL position is determined and AstroTortilla calculates difference and issues movements to the REAL position of the target
7) Steps 4..5..6 are repeated to confirm position

Especially if the GOTO calibration or mount setup isn't perfect or other factors impair the accuracy of mount movements, this method can avoid a lot of frustration. These advantages come at a price -- no it's not the price of the software. The one I use is free.
The price you "need" to pay is the need for a laptop to control that whole camera + telescope setup. If you are imaging with a CCD or an autoguider, that laptop already is part of the equation.
OTOH, if you want to travel light, just using a (smaller) telescope + mount + SLR - laptop, this is not for you. HOWEVER, even if you use a lightweight setup, an astrometry tool still can be useful to analyze the images you have shot.
