one in a thousand!

Posted By Greg Kim
Larry I had a night like that (one) and it has not been repeated. Try to keep the memory alive. Interestingly enough it was in December as well and viewing Saturn.

Christmas Eve under the stars

Posted By Greg Kim
In Northern California we have not been given the chance, we have been shut out for at least 5 straight nights. Thats like a month, my eyes are getting crossed looking at this screen. How the heck did you have clear skies in S. Cal on that very night?? And the next 4 nights don't look promising either. I need a Jet at 30,000 ft. :S

Saturn Opposition tonight!

Posted By Greg Kim
Here is a crude but accurate drawing of the moons of Saturn I saw 2-03-2006.
The one closest to the planet in the drawing was not visible in my 10" SCH but was seen in the 12.5" dob with direct vision. Unfortunately the fog rolled in at 8:55 PM (approx) and I could not try in the SCH with averted vision. The inner ring was also still visible in the 12.5".

10" or 12" Intelliscope?

Posted By Greg Kim
I have looked through both and the 12" is better. If you observe mainly from the backyard you will need the 12 inch as the brighter the skies the fainter the images at the eyepiece so the 12 will show more. It's like driving a few miles out with a 10 but you are at home. You need the 12 period. I've been through them all 6" 8" 10" 12.5" 12" from the backyard the 12 is the way to go. The 12 is also a great planetary scope with perfect colmination and...a cooling fan. The fan is a must. Do not forget this or you will think the views are sub par compared to the past scope. You will also need a 2X barlow, Orion's shorty is just fine and then use anything from a 40 MM eyepiece down to a 10 MM and the view will be sharp. I barlow all my dobs. It's a coma corrector that works.

What you see in which scope (size type, etc)

Posted By Greg Kim
The pictures are not the actual view for me as I can see the red spot and the transit shadow more like 8 real defined but the number of belts may not be as visible as the photo and appear more like 6. This is out of a 12.5 dob.
My guess is the photo is going to show more belts as I'm sure you modified 8 with photo shop or the like to get 1 and if 1 was the condition then less belts would actually show.

Newby with an Orange Celestron 11

Let's see the front of the scope (corrector) upload a picture. My guess is it's fairly clean.
You can remount the scope back on the fork easily and use as is on the wedge to first see if the optics are any good (should be fine) and then decide if you want to send it to Celestron. Most cases cleaning is not hard to accomplish especially if the outside is all that is needed.
Again let's see the corrector.

sky align -- reticle eyepiece helps!

One tip is to always use the right arrow button to move the scope to center the align star to it's final position as it takes up any gear backlash. So use the left button to go off center with the align star if it is past the center and then finalize with the right button. Do this on all align stars and accuracy will increase. Also make sure the scope is level and if you want to go one step further also only use up button last just like the right button . In other words finalize the star position in the cross hair with up an right buttons only.

focal distance, advice needed

Posted By Greg Kim
Andrea
I have the same story on an Orion 10" but the Newtonian version, for some reason the primary is too close to the secondary, an extension tube will work to get the ep to focus but the real fix is to move either the primary or the secondary further out and away. However just moving the ep out a 1/4 inch won't hurt anything. One other quick fix is to tighten all the colminating screws to move the primary further away, but you will have to recolminate. I did try this but the effect was small and not worth the effort to get perfect colmination again.
In short nothing to worry about if you come to focus even at the end of travel and no vignetting occurs.
