Focal or max magnification ?

[Mansnake]

Hi guys another noob question im afraid.

i want to do lunar, planet astrophotograpy using a webcam and trying a DSLR now and again.

im looking at scopes on FLO and im not sure if i should be making my desicion on focal length or maximum potential magnification.

the scopes im looking at are:-

Skywatcher Explorer 130P

Skywatcher Skymax 102 SynScan

or

Skywatcher Skymax 127 SynScan

which one would be best for my needs ?

thanks in advance guys !

For lunar and planetary imaging I would go for the Skymax 127.

Thanks Peter that was i leaning towards for its 1500mm focal length.

just so ive got a better under standing, if i were to use more than a x2 barlow, say a x3 instead would i be pushing it ?

It might be a bit too much at x3.

Yea I thought so. I'll stick with the x2.
