The other day I visited a telescope store and compared the sizes of an 8 inch and a 10 inch SkyWatcher dobsonian. They both seem to have similar lengths, although the 10 inch is a little more wider/bulky. That aperature for the 10 inch looks really inviting. I guess it would bring in twice as much light at an 8 inch? That would be amazing!

I'd say that in terms of length both scopes are similar in the area needed in a car to move them around. Also, the weight is similar. 8 inch has 20kg, whilst 10 inch is 25 kg. Interesting. Would there be much of a difference in the effort required to move around a 10 inch compared to an 8 inch? Perhaps not much if you had a good little trolley? The main requirement may be the heavy lifting.

The main difference is price. 10 inch seems to be 200-300 buck more in price. Maybe I should consider saving up more dosh going for it???

I notice that on a 10 inch the focal length (1200) is the same as on an 8 inch. Is that bad or good?
