Subject:	ETX DS DSX Polar Align
Sent:	Friday, May 11, 2007 00:15:48
From:	Kelvin Obbard (kobbard@hotmail.com)
Since I last wrote (saying how wonderful the little ETX90RA was that I
had got) I have have bought a (very) cheap ETX125 OTA & an (equally
cheap) DS/DSX mount/tripod. I have made an adapter bracket to fit the
OTA to the mount and all is well.

However; I have one big, thorny question.

I know that the DS/DSX 'scope/tripods cannot be Polar Aligned a) because
the mount/tripod arrangement physically cannot be set to Polar Align &
b) Autostart does not give Polar Align as an option if you select a
DS/DSX scope.

What I want to know is: If I I adapt my 884 tripod to take the DS/DSX
mount (fairly easy) The scope could then be placed in the Polar Align
position. So that just leaves the Autostar problem. Could I not simply
select a different scope in Autostar (say an ETX125) that DOES allow
polar alignment?

From what I have read elswhere the ETX & DS/DSX have the same gearing -
so surely the above arrangement should work - or am I missing a BIG
point???

Obviously the DS/DSX mount is a single arm - rather than the ETX double
armed fork - so I gues it would rather less stable. But does this mean
that a single arm cannotcope with being Polar Aligned?

Mike here: I don't have a DS/DSX to confirm it but I suspect it should work with the ETX model selected (assuming that mount even shows up). And stability could be an issue as there could be more vibration.

And:

Thanks for that Mike.
 
I mainly wanted reassurance that I am not missing something obvious. I
will give it a go & let you know how it goes!

Subject:	DSX-90AT Star Halos

You were correct, the halos were a result of incorrect focusing.  Not
sure if you know much about the DSX-90AT, but it seems to have a poor
mount resulting in a fair amount of vibration.

Thanks!

Tonight may provide a clear sky; I will see if I fell into the trap you
surmise (I think I probably did since the moon and Saturn quite clear
and well-resolved considering the Minneapolis lighting).  Thank you very
much!

Subject:	New DSX-90AT Star Halos

Just purchased a DSX-90AT from Meade's factory outlet.  At the 2 powers
available to me (9, 26mm eyepieces) I cannot focus stars without
observing halos.  Is this a collimation problem?  What are your
recommendations?
 
Thank You,
 
Bill Fowler
Mike here: Just to be certain, when you focus on the stars they are pinpoints of light? When you focus on another celestial object like the Moon or a planet the focus is in the same position? I ask because a common new user mistake is to try to use the focus as a "zoom" and magnify star images, which won't magnify due to their distance.
