View Full Version : The question about EQ2 mount

2010-Aug-20, 06:34 PM
I have a question that seems interesting for me. :)
Here is the mount: http://www.skywatchertelescope.net/swtinc/product.php?id=49&class1=3&class2=302.
As it is shown in photo below - there is marked a screw that, as far as I know, regulates pressure of a spring in mechanism of Dec. fine adjustment. And, as I know, proper setting is when that screw protrudes for about 8 mm.
And here is my question - how its setting affects fine adjustment? There should be a reason of placing that screw. Maybe it causes that after a full rotation of fine adjustment's handle there are differences between changes of declination (I mean, when it protrudes for 8 mm and we turn the handle for 360 degrees - declination changes for e.g. 1 degree, and when it protrudes for 16 mm - Dec. changes for 2 degrees), am I right?
I ask this question because I think the proper setting can help with viewing different objects (moon, planets or deep sky objects).
Best regards!
P.S. I am really sorry for my poor English. :(
And here is a photo.

No one can help? Maybe that EQ2 mount is not so popular, but maybe some of you have a similar mount with analogous screw. :)
