Yes to all of the above, all great ideas.
I imagine it will be a combination of:
1. Why a GS Dob is good for beginners starting out in astronomy
2. What it's good for (ease of use, setup time, big aperture for small buck), and what it's not good for (astrophotography, goto, tracking etc)
3. Some links to some how-to guides for tweaking the GS Dob, either on my mods page, or mods that other people have done. The Resources->HowTo section is empty at the moment - i'm happy to fill it up with all of YOUR gs dob mods.
4. Some links to some good, simple and easy to use references for collimation of a GS Dob, including ones with tools (laser/cheshire/etc), and without the use of tools (film cannister etc)
5. Some more advanced tweaking and mods ideas etc, whatever Geoff and anyone else submits.
This will be a community effort, not just input from 1 or 2 people - i'm happy for everyone to chuck in their 2 cents because almost everyone has done
something to their GS Dob
Keep it coming.. let's get it rolling!
