Hi Darren.
Thanks for input. Yes I agree with you, the view from 6” is far superior to my 4” ETX Mac. After seeing Astroman's pier I make up my mind to build similar pier. That will give me more time for observing. I stared scrounging for pipe and steel plate. I will not make it as beefy as Astoman. It will carry just GS SV1 mount and maybe 8” x 800mm sometimes-in future. Just clip the OTA on and maybe touch up alignment (I hope). I have ordered Celestron 102 and will use it when I go to my sister’s farm for weekend. Should pick it up tomorrow. I will let you all know if it is any good. My ETX-105 is a nice scope and when used with the Sky Map to synchronise it on chosen star it will keep the star in the view indefinitely. But after slewing it must be left alone for minute or so, to settle down. The problem for me is that at F14 image is too dim for my failing eyesight. I use it for imaging or to view the stars on the monitor instead in eyepiece.
