Thanks Barx1963 and others for all your help, you are right the bigger Dob is the better.
I have researched like mad, I even have had multiple
Dreams of shuffling and puttting EPs into perspex holders?
Last night I used up 1 GB of my 8GB monthly allowance (on wireless) on youtube comparing what I would see with an 8 inch, which would be fantastic,compared to a lower Dob.
But today I discovered all my lawn mowers are cactus.need a new one.(will need at least $300 to buy one.
So unless a 8" appears for sale around at most $300, I will have to go for a skywatcher 130p.
No good Skygazing with 1 foot high grass and snakes!
Probably a payback for selling my 20mm refractor in 1987, should have kept it.
I will just start from scratch, learn the sky and constelations, with the 5 inch, but I will save up for an 8 - 10 or even a 12 inch in 8 months time.
Thank y
ou for all the good advice.
