It is a bit slack for GSO though, we should not even be talking about this problem. Here is the link if you are interested http://www.iceinspace.com.au/forum/showthread.php?t=114061
Once again guys, thanks for the help. |
Hi Brian,
That will give you up to about an extra 10mm of collimation adjustment, depending on which bolts you use. That is probably going to be enough to enable the scope to reach focus with all your eyepieces. Certainly the easiest option to try first. Just be aware that this "may" affect the scopes ability to hold accurate collimation as the scope is moved through its full motion range in altitude. With the design of the mirror cell used in these scopes the shorter these bolts are the more stable will be the scopes collimation as it is moved through its full motion range in altitude. You can check this by collimating the scope when it is pointed at an altitude of say about 45 degrees. Then point the scope to zenith and check the collimation again, then point the scope near the horizon and check the collimation again. It may or may not change.
Cheers,
John B
