You don't think the tube will fit across the back seat?

I definitely won't buy a scope that I can't fit in the car
Put your money in the bank and wait for the AUD to rise further - your buying power will go up.

Learn a lot more with the 8". Much easier to learn on an 8" then on a 12" - I know.

In my Falcon, I would have to remove one rear internal door trim to fit the tube across the seat. You could buy a Hummer?

A 4mm GSO plossl? Paperweight value only, I think. I found the eye relief in the 6mm too small so you must have your eye jammed against the eyepiece?

Yes, the Televue plossls or Vixen LV (better eye relief) - try the second hand market - put out a "Wanted".

Sounds like you were observing Jupiter too low. It is at opposition on 15th so is directly overhead around midnight. However, with a dobsonian mount, it is a struggle to observe at 90 deg elevation, until you learn some tricks (1. - grab the dob base with your spare hand to rotate in Azi. 2. - prop the base base up on one side so the base points to 70-75 deg elevation). Anywhere above about 70 deg should reduce the air column you are looking through.

Your dob may already have an end cover with a reduced aperture hole. Is there a 5-7cm cap that pulls off to leave a hole? Try that - just move the hole to where it isn't over an arm of the spider.

And you have to check that collimation!
