Hi Pro's -

Going to leave my 4.5" Newt EQ Reflec under my bed and move to the infamous "DOB" this christmas.

Never seen through a Dobsonian scope before...have made a move to them because they are cheaper and apparantly good for DSO?..

And also the new release "collapsible truss-tube" from Skywatcher is excellent as portability is a major concern.

However could you guys please tell me your significantly experienced opinions on the following decision.

They say the larger the better.. so would it be feasible to get a 10" collapsible dob rather than the 8"? I will be buying from "York Optical" and the price difference is $425.

8" Truss-tube Dob is $722
10" Trust-tube Dob is $1.147

Its quite a significant price jump.. what do you guys think? - is the price worth the difference in regards to quality of observing, amount of objects etc..

Currently live in Manly-Sydney so the night sky is not the best however, usally trek about 1hr out of sydney when observing.
Have never seen anything greater than saturn and orion nebule with my current 4.5" newt EQ. Tried Jupiter once..but was all blurry..

This amount of money is a large amount - only 21yo and dont want to spend to much on constant upgrading of scopes so when this one is purchased either 8" or 10" - It will be staying for a hopefully a few years!

If you have ever upgraded from a 8" to 10" in your astro years - what did you think of the difference?

Really appricate any advise given
