Hi John,=20
Last night while I was looking at Mars, I noticed It was hard to get the =
Focus working. I would turn to look at the Moon and everything was fine. =
But I figured I might as well try to do a star Collimation, so I pointed =
towards Polaris. I made a Donut. I could clearly see that the black dot =
was off to the left side. Using a 33mm EP. I started to screw in Bob's =
Knob's. I noticed they were loose. So I centered the donut in the EP. =
(The scope was tracking at the time).There are three screws I decided to =
turn the top screw to see which direction it would move, and to see if =
there was any change in the black dot. It had moved down, with no =
movement of the black dot. So I moved it back,just a half turn. I then =
half turned the left screw to the left It moved and I started to see the =
black dot moving towards the middle of the eyepiece. I stop. re-centered =
the donut, and turned the same screw half a turn to the left again the =
donut moved left and the black dot moved even more towards the center of =
the donut. stop re-center the donut in the EP. (I could clearly see that =
the donut was starting to look much better, with the black dot moving =
towards the center.) I kept doing the same thing until the black dot =
started going in the opposite direction. so I replaced it and all you =
have to do there is go backwards, turn a half turn in the opposite =
direction. Once I got it close to center, I started to turn the right =
screw, and started to do the same thing Turn the screw half a turn to =
the left and It moved the donut and the black dot up towards the center =
of the EP.That's when I figured out that on my scope anyway the right =
screw makes the dot go up. the left screw makes it go right and the top =
screw makes it go down. after a few more adjustments, and re-centering =
the donut on the EP I was so close to perfect, I started to see the =
concentric rings . That's when I said I've got it. Once the donut was in =
the middle of the EP and the black dot was in the middle too, I made the =
donut even smaller, making the black dot move a little to the left. But =
by then, I knew which screw to turn to adjust. and presto Very nice =
collimation! I then looked at Mars and Oh My GOD! what a difference It =
made all of the white ghost affect around the 2 sides of Mars gone, I =
thought It was because It was so bright, I then focused on the Moon and =
I almost fell out of my chair. I could see so much more detail then ever =
before. and the stars Looked so nice and bright and in focus.
=20
Now what other EP should I use to do more collimation if I have too? But =
I have to stick to Polaris, because of my back as it was, I was having =
to hobble back and forth every time, (and that's with the Dew shield =
on!!) But It takes time and patience to make it right. I do want to try =
a yellow moving star I'm hoping I'm not that bad off in collimation NOW =
anyway! It should be easy to fix!
I noticed that Bob's knob's were screwed in almost all the way when I =
was done. Which is good, You want a snug fit not over-tighten! Thanks =
John for all The HELP!! It finally sunk IN! (ps) You're right John I =
don't need none of that fancy SCT laser collimation STUFF! Thanks you =
just saved me plenty on money!! The STARS truley are the best tools!
