Over in the
bargain achromat thread there are a few saying that small refractors are beating their GS dobs on planetary views. This shouldnt really be the case.
I want to raise awareness of the fact that many GS dobs leave the factory with the mirrors mounted in a less than optimal way, and at the same time take a bit of a survey.
When we had our Vic meet a few months ago, there were three other GS dobs there, two that I got to look through. Both of them had obvious issues.
If at least two out of three from this small sample had issues,along with mine when I first got it, I wondered how many others out there were like this. Thats what prompted me to put together the
GS optics how-to
In the case of dave47tucs scope, his primary was clamped in too tightly.
I havent heard back about Migs scope yet.
How many of you have checked your GS dob ?
