Firstly, do you have a laptop that you can take out to the backyard (great for using programs like starry night) and also is your backyard grass or solid like concrete? I have just bought a 44 gallon drum trolley that is 610mm wide, the dob base is 560mm wide. As i have asphalted driveway, i wheel my dob complete out to the driveway. very easy
- springs not a problem
- this is the best link i know to help, it also show the difference of a still night vs turbulent http://astronomy.trilobytes.com.au/m...iterseeing.htm
- it takes getting used to, everything is upside down and left is right. after a few nights, you have this down pat. yes sometimes i do bump it especially at high magnification, when i am looking thru the finder. The earth rotates quite quickly so you have to follow the rotation. not a major issue for me
- not with the dob no, the only way around it is with a "goto" system. I am in the middle of motorizing my dob so i can tell it where to point, but that is not a negative. The excitement i felt tracking down uranus and neptune for the first time by hopping from star to star was exhilarating. My heart was beating fast, i was holding my breath and i punched the sky when i found it. I would not have had those feelings with a goto system.
- check you measurements, bintel or andrews should give you the measurements
Have fun
