lessons learned

Well even though the newtonian isnt perfect in collimination i could wait no longer so went out for a trip through the stars. The sighting scope was out of kilter so i decided to adjust it while the scope was nearly vertical.Why didnt someone tell me this was a definate no no . I loosend it a bit too much and away she went right into the eye .Fortunately no damage to it or me.Definately made mental note to do things on a more horizontal level.
The second episode of the evening was while i had the mount released so i could pan across the sky without useing the controls.Suddenly I had the scope in my hands totaly detached from the mount .When i examined the allen head bolts i found that they were way too short.Only 3 threads went into the mount.What i have learnt is check and double check.
I knew that bigger was better but left one factor out of the equation and that was price.I now realize that $600 for a brand new 8 inch reflector is cheap.You pay cheap you get cheap.
Good lessons tonight but realy hard on the ego.

We live and Learn. That's what makes it all fun, as long as we can laugh at ourselves.

Was yours a skywatcher or GSO brand?

Doesn't seem to matter how much you spend on a scope HOSaturn, you will always find something that is not right. Scopes, mounts, even eyepieces will dissapoint a lot of the time. You tend to tweak a lot, or work around things and accept them as they are. My C11 tube is worth thousands but that doesn't stop the mirror flopping side to side a tad when it wants to. A common problem.
