Thanks Joe. I understand thaat with a 50x mgnification, the object is almost always in the FOV. Say that with the Argo Navis and 11mm nagler (and then 145x)...
Dear Bernard, Yes, I agree that the initial alignment is important. I usually align at about 364x (Nagler 5MM) or higher to center the alignment stars. Also, I...
Greetings! I have a 20" SM with Startracker drive and Sky Commander. I have friends with ServoCat and various DSCs. I wouldn't trade them! Seems my friends...
Hi Group, Thanks to everyone for their inputs! Granted, what matters really is the ability of the scope to deliver the best images possible and you rightly...
Dear Francois, Congratulations on your decision. Just as a side note, if you are getting the XP4 version of the Sky Commander (standard now), you can download...
Francois, you can use an Argo Navis computer with the Sky Tracker system - as I do with my 18" Starmaster. I went to the AN a few years ago because the bright...
... That won't have an effect on the image. And even for imaging, where you want good tracking, the tracking is set based on where it thinks it's aimed (in ...
... There's a three-step brightness adjustment, and there's also an internal trim pot that's supposed to adjust it even more, but that didn't work on ours. ...
Francois, Congratulations. You are in for glorious views. You can switch out the encoders and go from 4000 to 8000 or 10,000 tic encoders. The Sky Commander...
One final comment on the "ticks" on the SC. You could change out the encoders to 8K, and there is a setting in the SC for the encoder count. There is a warning...
Joe, You might not know me, but I have done it. I think it is an improvement. The 8000 step encoders are from the same manufacturer as the 4000 step encoders,...
Thanks, Joe. Looks like I now know someone who has done it (after you introduced yourself to me:-)) Thanks. Were you able to just swap them (a 10 second job)...
Dear John, I know that in 2005 Victor did make a software change to handle faster movements (specifically for very small scopes) that caused the unit to fail ...
... No, encoders themselves are capable of very high speeds- they're routinely attached directly to motor shafts. But the device reading the encoder has to ...
... And accuracy is an important concept here. How these encoders work is that they "read" opaque markings on a circular disk. A simplified view is that for...
I have used the 3.338 Sky Commander with both 4000 and 8192 tic encoders with good performance with either set. I do not find that I need to realign on objects...
When I called about the higher speed setting I was told to turn it off as there were still bugs at low temperatures. Floyd ... to fail ... speeds ... in the ...
... The encoders are from US digital. -John ... ____________________________________________________________________________________ Expecting? Get great news...
... S2-1000-NT for 4000 tics (actually, 1000 tics with quadrature). I got my 8192 tic encoders from JMI, part number J68163 and labelled as "Optical Encoder",...
"I went to the AN a few years ago because the bright green LED screen on the SC was very annoying" I put a piece of red cellophane over the Sky Commander...
... Something that I just thought of. If you have a dew shield for your Sky Commander you could put the cellophane on the dew shield. That way you could lift...
Resurrecting this thread. :) Who is going so far? So far we have Christina and hubby LeGrand - 18" StarMaster Tim Hall - 18" StarMaster Shannon - 20"...
... All Starmaster owners know that good ideas and things come from Kansas. Of course they come from Arcadia but I was glad to offer the idea about the dew ...
I tried that Mike, but like the other poster, I was interested in preserving my night vision. With the cellophane, I had to set the brightness to maximum, so...
