What are the pros & cons?

Thanks

I've been given the use of dobsonian mounted scopes before and have always found them to have the tracking problem which goes with any altazimuth. It's a pain, to put it mildly, but if you're not all that worried about photography, then you might tolerate it. A Poncet platform can go a fair way to resolving this.

In their favour is the fact that they are usually very stable. This comes from the weight/low c of g - but which in turn gives you a problem with mobility and transport!

All in all I prefer an equatorial for the sheer simplicity. You're one step ahead of things already.
