no polar scope, no finder scope, no hand
controller and a small-ish 4/3" camera chip
(compared to a wide field eyepiece) and unknown
orthogonality, you have set quite aninteresting
challenge for yourself.
of like one of those survivalist reality shows
where the hero goes naked into the den of an
angrygrizzly, covered in bacon grease and armed
only with attitude and aQ-tip.
are my suggestions:
Get a cheap diagonal and low-powered eyepiece.
Get a polar scope. Even a used PASILL4 is way,
way-better than nothing.
Get a cheap unity finder scope. Something
like a Rigel Quickfinder or a Telrad.
Learn how to drift align.
Learn how to adjust your orthogonality.

******Newb Alert :)***********
What is the best way to go
about getting better GoTo's with what I
currently have as a setup? The mount is in an
Observatory on a pier. Last night was the first
real chance I have had to try and get it Polar
Aligned (just visually by looking through the
bore hole) and work on GoTo accuracy.
Unfortunately, I am a bit limited in my choices
of how to go about doing this.
I only have a refractor with
an ASI1600 camera on it. I have no RAPAS or
Keypad or finder scope.
I initially tried to just
slew to a star (Vega) but the star was not in
the FOV (I am using SGP to see what is in the
FOV). So I tried slewing to Andromeda (as it is
a pretty big target) and it was in the FOV, but
not centered. So I centered it using the
direction buttons on APCC. I then made sure the
RA/Dec were correct andhit the ReCal button.
This works great for slewing to Andromeda (as no
matter where I am now if I select M31 -
Andromeda - the mount puts it dead center. But
still no other targets are in my FOV.
What is the best method of
getting the mount accurately Polar Aligned,
given that I don't have a R8
APAS/Keypad/finderscope so that my GoTo's will
be spot on?
Also, isn't part of the point
of doing a ReCal to help with the overall
pointing accuracy of the mount?
As you can tell I am totally
new with this mount (coming from a CGEM and the
familiar 2+4 and ASPA) and would like to get
this figured out. I have been through the
manuals but can't find an answer to this - or at
least nothing I quite understood.
