my three dobs are all quite different beasts. the 6" f11 is a low aperture, slow focal ratio planetary and double star scope which sits on a equatorial platform. it's great for quick sessions as cool down is not long and works really well at high powers (e.g. 300-450x) four double stars when seeing allows.

the 12" f4 I bought as a grab and go with a bit more aperture. cooldown is not too bad (maybe half an hour for low power observing). it fits the Pleiades in the view of my low power eyepiece and I'll be making a suitcase / travel dob out of it eventually for camping etc.

the 16" f4 I use as my favoured scope for all occasions. it's just amazing. it takes a while to cool (maybe an hour for low power and fully cooled in two hours) so it's best at weekends or summer evenings/star parties. but the wait is worth it. it's a LOT bigger than even the 12" f4. here's a pic of them together (the 12" is on an unfinished at that point base)
