Due to personal reasons, I had to stop the hobby for a while. When I came back
to the hobby sometime in 2008, I started to look for a mount to replace the
William Optics GT-1 (the SS2k was not working well for me as it would always
drift in Dec after a one star alignment.), after some serious consideration I
decided to go for the Mach1GTO. The mount is not avaliable for immediate order
and I placed myself on the Astro-Physics waiting list on 8th March 2009. On 17th
Dec 2009 I received an email from Astro-Physics that the mount is ready for
ordering. I send in my order to Astro-Physics on 21st Dec 2009 and the mount was
ready to ship to me on 3th March 2010. Now after using the
Astro-physics Mach1GTO for close to 1 year, I do not look at or
desire anything else (within it's class). It cost a lot but it works perfectly
out of the box. There is no need to tweak anything. For imaging the Astro-Physics
line is well worth every cent spend. The built-in polar alignment routine in the
keypad is quick and easy to follow. It allows you to start polar alignment
before end of astronomical twilight. Using the built in routine, a typical polar
alignment could be complete in less than 20mins and yet be sufficiently accurate
to allow 5-10mins unguided exposure yielding nice round stars. This feature is
very important as polaris is too low to be visible hence making polar alignment
scopes useless here.
