[Most recent version of ACC Ascom Driver?]

I'm curious about what is the most recent version of ACC Ascom Driver?  I have an OK-3 focuser.  Mine is version 0.0.2.3 and appears to be working OK except for an occasional homing problem.

Thanks,

Michael

Thank you Mark. 

 

I've been imaging to about 85 to 90% humidity recently without a dew shield.  The results look OK.

 

In your experience, why should the fan not be used all of the time?

 

Thanks,

Hi,

 

I have the 12-inch Newtonian located in a remote observatory in San Diego.  This year has been unusually humid.  I currently do not try to image when the humidity goes above 80%.  I'm thinking (actually hoping) that may be a little conservative.  I assume the rear fan will help a little.  

 

I'm curious about others experiences about at what point dew forms?

 

Thanks,

 

Michael

Thanks guys,

 

Now for the scary part, doing it.

[Cleaning secondary and corrector]

All,

 

My N12 has been in an observatory for several years without a lens cap.    Both the secondary and the corrector have crud on them which will not brush off.  Please advise on how best to clean these surfaces.

 

Regards,

 

Michael

It looks to be 1-inch (25mm) wide and about 1mm thick.  Although mine is pretty compacted.  Do you think this would work?

The felt on my N12 tube rings has come off.  Some of it is lost.  Can anyone point me to something compatible?
