Not a big deal.

The problems as I see it were:
- I wasn't dark adjusted at all
- The seeing is not great tonight
- I am inexperienced
- Mirrors hadn't had sufficient time to cool
- The mirrors are ineptly collimated - in other words, really quite uncollimated
- the mirrors are a little dusty because mine was the display model in the shop.

However. Seeing the Orion Nebula - even though it didn't blow my socks off - gave me great faith that things will go only up from here!

CHEERS!!!

Add maybe that your expectations were not realistic.

Probably worth taking the mirrors out and washing them (there is a right and wrong way of doing this).
Also recollimating the optics will be worthwhile. (I'd try that first before washing the mirrors , that might be all that's needed, a bit of dust on mirror is tolerable).
Dark adaption is important (at least 15-20 minutes of no bright lights) will make a huge difference.
Pretty hazy tonight here (Gateshead), can see no clouds and can see stars , but there is a lot background reflected light off the haze. I wouldn't bother getting the scope out under that kind of condition - seeing is bad.

Concentrate on objects that are relatively high above the horizon, their light passes through less atmosphere and they look better than when lower in the sky.
