Thanks for the tips

Collimation is slowly making sense now. Heck I can almost do it right. I have got my scope pretty well collimated now. The secondary mirror seems a bit out of whack though.

I think the tilt of my secondary mirror is a bit out. I go through the steps of collimation aliging the secondary mirror to the focus tube (I am pretty sure that is right). Adjusting the tilt of the secondary mirror is tricky though. I never seem to be at a point where I can see the whole primary mirror. I can almsot see all of it at times but I just seem to miss a slightest bit of one edge at most times (if that makes sense).

I have tried racking the focuser in and out to help see all the primary mirror however the most I seem to see is about 98% of the primary mirror.

Hmmm maybe I just need to fiddle around a bit. Hmmm do you think the mirror could be out of alignment with the focuser after all. I swear it looks circular and I can see the whole mirror when I go through the first steps of collimation (aligining the secondary mirror). But I am a bit unsure of myself in any case. I mean, I look through the focuser and see a nice round, centered primary so it should be ok, right?

Arrrghh, maybe I just need more practise...

I am getting better at collimation. At least now I am starting to make more sense of it all. I can not wait to get the collimation right. The views with a slightly out of whack scope are pretty GOOD so I can imagine when I get it collimated it will be awesome.

Jupiter looks pretty darn good this month. Not to mention the Moon, oh and those stars over there, and there, and there and...
