I have the Sky Commander with the Losmandy DSC and the manual states
4000. I did not believe that number and entered 4096. It has worked
just great. With a reasonable drift align (no movement for 5 minutes
at 220X), I get the image on my CCD with my 4" Tak and ST-7E about 90%
of the time. When it is not on the CCD it is close enough that star
matching with TheSky is easy and the object is quickly moved to the
chip.

Yep, I see the 4096 on the web site. The copy of the manual I have has
"4000 nominal" in the same spot. The encoder housing is the nicely anodized
aluminum and matches the finish of the rest of the mount exactly. The
manual I have was obviously printed from the web site at some time in the
past. Maybe this was an over looked left over from the Dob kit manual and
it has since been corrected?
At any rate, I'll definitely change it to 4096 and give it another try first
chance I get.
Thanks,

Ray,
If it is the Losmandy DSC you will need the 4096. The Losmandy unit is
really the Sky Engineering
Sky Commander DSC which is usually installed on Dob's, which as I said
before uses the larger
housing 4000 encoders. The Losmandy encoders use the smaller housing
because of the space
requirements created by the gearing. Did you notice the nice anodized
encoder housing and metal
gears? Go to Losmandy's website here and it does say 4096 (in red).

Thanks, Don. I'm buying this mount used and the encoders were installed
by
the current owner. All the labels say Losmandy so I'm going to try the
4096
setting. If that doesn't work, I'll follow your suggestion and remove
the
back plate to see the label you mention.

Ray,
Every encoder I've seen has had a label on the back of the encoder
housing
that shows the counts per
revolution and also the wiring diagram for the pins. If your using the
metal housed encoder, you
have to take off the back plate and bend down the circuit board the
see
the label on the encoder. If
is says 2048 you need to use 4096 as the setting. Come to think of it,
if
you are using the Losmandy
encoder kit it has to be 4096 as there is no 4000 encoder in the small
size (S1) encoder housing.
The 4000 encoder only comes the The larger (S2) housing which is over
2"
in diameter. The 4000
encoder is found most often on DOB's were space is not a problem.

Hi Gregory,
Trying the procedure you recommend had already occurred to me and I
plan
to
give it a shot next time out. Based on feedback from this group I
also
need
to reset the encoder resolution from the default 4000 to 4096. I
can't
find
anything in the documentation or any marks on the encoders that
states
what
the correct value should be but based on everything I've seen here,
4096
sounds like the correct choice.
I'll report back here after my next night out with the mount.
Thanks to everyone,

Ray,
When you centered on vega and hit enter, do the DSCs tell you
anything
like the Lumincon DSC's? ie warp factor =0
Also, after centering on vega, hitting enter, then asking the DSCs
to
guide you to M13, when you get to where ever the DSCs suggest M13
is
located try sighting the cluster in and aligning on it. Then see
if
your
next target is better centered.
Take care,
Gregory david Stempel
