How inaccurate is your GE mount's lattitude scale?
Well a piece of thick dowel wood - slid down the finderscopes tube and then centred, followed by a ruler along the base and a protacter to measure the angle of intersection showed me - 6 degrees on a brand new CG-5 mount. So for 33.5 lattidue I had to point to almost 40; and I wondered why my polar alignment was poor.
So I popped off the plastic cover, marked the proper location for the 90 degree line, adjusted correctly to my lattitude, then got out the trusty hot glue gun and 2 minutes later any error is well less than a degree.
Anyone else try to test this? I was surprised how inaccurate the mount's latitude scale was - and so easily corrected. They must have just bunged it in by eye, wouldn't you think these pre fabbed, machined pieces would either have a 0 and/or 90 marking accurately marked and construct the plastic scale so it could only fit in correctly!
What are other peoples experiences with their mounts?
