Guiding Tolerances was (RE: [APML] IC1805, IC1848, h & chi)

["Thom Iwancio" <tiwancio@sc.rr.com>]

Paul, I found Robert Reeves' website to be a valuable resource for
guiding tolerance information. 
 
http://www.robertreeves.com/class11.htm

With careful alignment and a little attention to detail you can get some
wonderful wide field shots without too much trouble.  

BTW, how is crummy is the weather?  I am going to be in Manchester most
of next week and will likely do some sight seeing in Chester on
Saturday, but the forecast does not too good.

Best regards,

Hi Andreas

I have just seen your picture of IC1805,1848. Great image. I am about to
start taking pictures my self, I have a Vixen DX mount plus SS2K and I
am
going to use a TeleVue Ranger together with my Vixen GA-4 to guide with.
I
will have to manually guide as I do not have access to an ST4. The
camera is
an Olympus OM1 fitted with ether Olympus 50mm and 135mm or Soligor
250mm. I
am also going to try some shots through the Ranger and I will have to
use
another guide scope probably my old 60mm Prinz refractor or a 50mm
finder
fitted with the GA-4.

Because I am guiding manually, can you or any body else here give me
some
tips about guiding and guiding corrections.

Regards.
