Notes
|
7 May 2023 - Las Cruces, NM
This image is LRGB.
The new AP mount performed flawlessly - no "three-point
alignment" needed. Once I used the RAPAS to do the polar alignment -
I had it slew to this target (M51), and it was already in the FOV of the
TOA-130 at 1000mm FL!! Notice this (the full size) is uncropped, this is
because the tracking was incredible on this - not a single bad frame due
to tracking - not one.
