distance off center

Posted By Floyd Blue
Anyone know how to figure the distance off center (angled) at the end of a 11" beam if it off verticle by .0085"?
Would this be 11 x .0085 inch = .0935 inch? I was thinking this was the formula, but I am unable to find an answer in my books or on the net.

Clear skies tonight.

Posted By Floyd Blue
I just got some Ultrascopics in the mail today. I have a new Feathertoucch focuser and need to do some star testing for some changes I have made. Sky is clear, but the stars are twinkling like a Christmas tree! :^( First clear skies in a 2-3 weeks, but I fear it would not be good enough for star testing.
Ohh well, maybe I will put the scope up amnyway and see just how bad it is for viewing. Full Moon, so I guess I could look at it.

Do you dress up the welds or just leave them for strength.
Not knocking it, it looks great , but just wondering if the finished unit is the same?

A question of power

Posted By Floyd Blue
I was wondering what the maximum magnification was for your DOB with reasonable seeing? 300X?
Also, what is the highest power you have been able to use on the exceptional evening? 500X?

4 Hole Aperture Mask

Posted By Floyd Blue
Just another post on the mask. Last night I got to use it a bit with another observer. We both tried viewing Mars with and without the mask. We choose Mars because it was harder to see details than Saturn.
We both agreed that Mars showed better planitary details (white and dark areas) with the 4 hole mask. No spikes and very clear images. We were using 300-570X for these observations.
My friend was surprised to see that the mask performed so well. He commented that it seemed to improve the contrast and details were seen more easily.
I also tried it on Saturn with the same kind of results.
I am not sure just why these masks work so well, but they are very effective.

A little breath of spring to break the dull overcast.
Hope it lights up your day,

Scope for sale on Astromart

Posted By Floyd Blue
http://www.astromart.com/viewad.asp?cid=236812
This scope was a friends in the club and sold it to this gentleman. Really a fine scope, a shame it is for sale again so soon and never even used for 8 months.
Makes me wonder why he never used it, but some one is going to get a good scope for a good price.

31mm Nagler Loose Lenses

Posted By Floyd Blue
Just thought I would pass on what I was told by Televue concerning the loose lenses in my 31mm Nagler.
1st, I was told that tightening them is just fine, and that I can tighten them as tight as possible with no damage or problem with pinching the optics.
2nd, This can and has happened during shipping from induced vibrations.
3rd, if I still find that the EP does not perform correctly after tightening the lenses, then I can ship it to them and they will fix it.
Good service and I got to talk to a tech imediately with no holding or "We will can you back". You just gotta love the TV people.
