Hi Phil, Well said and point taken! :) I was just hoping actually to get the best out of this bunch of scopes. One point though is that even if the mirror were...

I agree with everything you say there Phil, Its really difficult to tell the difference at the eyepiece and wavelength errors are often just numbers on a...
... The only thing that scares me about people testing their mirrors is that a lot of people are going to be needlessly concerned about mirror quality. Star...
In a simple Sentence !!!! "forget it" IMHO the theoretical maximum for a 10" telescope is 500X not 600X based on the rule of 50X per inch of Aperture. In...

Very true Robert, not many things worth looking at out of focus. The tests you mention are all good ones, although I am not a moon watcher at all (it puts...
Castor is about 60% easier than you quote: the two components are now separting and the 3 sec separation you quoted has increased to about 5 by now. (I know...

Geez! Here in Oregon, we've been lucky to have 2 or 3 clear nights in a month, never mind the seeing. Okay, last night wasn't bad; that makes 4 for April. ...

Hi All! I'm new to the group, but have been reading (and really enjoying) the VERY informative posts here for the past few weeks while I was trying to decide...
Welcome Steve. You'll get alot of good views out of that scope. I use my XT10 to punch through the local light pollution. You'll like the NOVAC observing...
Hi Gene Castor is not quite that easy for me Gene, it only gets to about 20 deg above the horizon, hence I am looking over some treetops that exude eucalyptus...
John, Interesting list.! My XT6 won't show the E and F stars in the Trap at 80x (it will at 100x) , but it will show Rigel's companion at 40x. Well, not now,...
Wes, I feel for ya !! If I had only 4 clear nights in a month I would probably sell my telescope, because knowing my luck they would probably fall on big moon...
Congratulations on borh! Three months my first child was born - A wonderful little girl. One month ago I received my first scope - A XT10 Today - My first post...
First off, I live in only moderately light polluted skies, and the broadband does nothing. I would go with the narrowband. Secondly, get an off axis solar...
Hi John, Nice list! However, for observers in the northern hemisphere, I think the double-double Epsilon Lyrae should be included in the list of tests, perhaps...
[Hope it is OK to post in this group as this is about a Eq mounted newt -- but it's Orion/Synta and it only concerns the OTA -- I posted here because this ...
An 82A Light Blue works well. An Orion narrowband is a good one for nebulas. Gives a strong greenish blue tint to what you're looking at. Craig Simmons ... ...
