Hi Programmer,
As promised, we shipped to you today an alternate set of Az and Alt tangent arm
brackets along with associated screws, washers and sleeves which allow the
tangent arms to 'float' with respect the mount.
With regards the OTA shifting from side to side with respect the rocker, another
suggestion is to obtain some self-adhesive felt padding such as used on the feet
of furniture to prevent it scratching floors. You can find a selection of material
at any good hardware store. Affix the pads on the inside sides of the rocker beneath
the Alt bearings.
Thanks also to Scott Tannehill for the various suggestions on getting the
mount ship-shape. Any slop, play, shifting or skewing you can address
will pay off in pointing performance. TPAS can help compensate for some
systematic geometric fabrication errors within the mount/OTA but no system
can ever compensate for a random error.
For the daytime encoder test, if you can position the scope somewhere
on the driveway in the street, something like the insulator on a distant
power pole makes a good target.
Once you have established the encoder direction sense signs, use AUTO ADJUST
ON, which can refine your estimate of the Altitude encoder reference point after
you perform a two-star alignment.
Please drop me an email at
sales@wildcard-innovations.com.au after you
have received and installed the alternate tangent arms.
Best Regards
