My SKYVIEW PRO does not work!!!

Posted By Andre Moutinho

Hi,

I have noticed weird things with my SVP mount.

1) The most strange happens when I try to keep a star inside the rectangle of an illuminated reticle. When I press on button (RA or DEC) the mount moves to the opposite side for a while and then to the correct side. I have checked the motors and they seems to move to the right side according to the buttom command. Then I have tried using the knobs and noticed the same problem.

Does anyone have observed this anoying problem and have any idea of how to fix it ?

2) Another problem is that the RA motor seems to move a litle bit slow so that I can observe a slow drift of the star. Any idea?

Thanks,
Andre Moutinho

Coma corrector doubts. How does it work ?

Posted By Andre Moutinho

Hi,

I have some doubts about the coma corrector as I haven't used one or even seen one in Brazil.
Using the coma corrector is the same thing as using a scope with slower f ratio? How can I compare this? Is a f4.7 with such device compared to a f8 or f12 in terms of ep performance regarding coma?
Does cheap wide angle eps such the BO SWA 32mm performs like in f12 scope if I use a coma corrector on a f4.7 scope?
I am confused about it.

Thanks,
Andre

GEM motor kit with goto, PEC and autoguiding

Posted By Andre Moutinho

Hi,
I have a GEM with no motors and I would like to install a motor kit that can enable the mount to have the following features:
- ADJUST GEAR RATIOS
- GOTO
- PEC
- AUTOGUIDING
I have already found that the #497 goto kit is a possible option. There exist other options available ?

Thanks,
