Maybe. Like a sequence of random coincidences. Argo burned out, then Servocat stopped working due to a broken cable HC, then the user incorrectly installed the jumper on SkyCommander. Although it

You may have a faulty hand controller cable. The hand controller may be getting power and ground but failing to transmit data to the ServoCAT. I just had this happen on my own telescope. BC

I assumed that a 12V external battery was used. If the user uses AC/DC, then it is his mistake. It has been explained many times and everywhere that high voltage cannot be used in the presence of

Are you certain you have a good 12v supply?

My apologies - I only read the first line about the Sky Comm not being recognized. Which version ServoCAT do you have - is the hand pad connected using a thin round cable with a straight plug at each

The problem is that his device does not respond to the motors control buttons. I do not know how this is connected to the internal fuse. Perhaps it only switches off the motor control chips, but this

see my reply to Rajeev re reversed power. Gary

Hello Rajeev, Sorry for the late reply. So as to why the AN isn't working I can't directly address that. If you accidentally powered it up with reverse voltage I believe it would have been damaged.

I think you mixed up the polarity of power supply for both Argo and ServoСat. The consequences are sad.

I'm looking for help in trying to figure out an issue with my (newly replaced) Servocat unit.? Everything was working until a few days ago, when my Argo Navis unit seems to have suddenly died.?

That sounds like a great tip, big thanks! /Gabriel

As for the azimuth bearings, take a piece of 24 or 26 gauge sheet metal, cut it about 2 inches or 50mm wide about 12 to 16 inches or 355mm long, then get some Velcro use the fuzzy piece and cut a

Thank you Mickey! Actually i did just that for the altitude bearings, but for the azimuth i could not access the surface with a cloth so i "cheated" but i know not to take corners again, not worth the

Beautiful image Gabriel , an important note about applying spray to the bearings, never spray directly to the bearings, because of the mirror and the over spray, always take a cloth or paper towel and

Here is 1 hour and 15 minutes on The Pinwheel Galaxy from yesterday. Last time i imaged this galaxy the seeing was very bad, i had better luck this time. 226 x 20s using ServoCAT Autoguide in PHD2.

Hi Sam, Your scope is fitted with incremental encoders and they have no inherent zero reference point. The zero reference point for the altitude encoder when the unit is first powered on is determined

Hey Sam... long long time no hear. I'm trying to remember - was it not you that (Jean and) I met way back in like 2001 or so - you had an observing site near I think it was Huachuca City? Anyway... so

Maybe its old age, but I cant resolve this issue. When I set up (Obsession f5/20) I basically have the scope pointing North and at 90'. Power on the Cat and Argo and it goes through initialing and

Thank you Mickey, very much appreciated! /Gabriel

Excellent images Gabriel, you keep improving with every run. Mickey
