off load ccd or keep to guide?

Hi all,

I am just getting back into using my telescope. I would love to eventually image galaxies etc as I find these both fascinating and beautiful. These will I guess need a guidesystem and I have been reading about these here.

I have an IS DMK21au04 that is surplus to my current requirements. I was thinking of selling it to fund towards a better mount (might even make one myself but I have a rapidly growing list of projects) but I am now thinking I should I keep it and use it as a guide camera when I have a system suitable.

Is this type of camera good or suitable for guiding?

It can be done but since this is sought after camera it would probably fund a guide camera with an ST4 port which simplifies matters, maybe.

For galaxies other than the handful of 'close' ones you'll need a long focal length and that means a very accurate mount and very good guiding. This kind of tracking accuracy doesn't usually come out of the box at average budgets. Possible, though.
