I'm looking for a way to connect Bonduelle guiding interface to a EQ5 mount with dual drives. Marnix Verschraegen [Non-text portions of this message have been...
Marnix, Are you asking the EQ4/EQ5 or HEQ5? This should be a good starting point. http://www.astrosurf.com/astrobond/eblxinge.htm The 4 signals (N-S-E-W) from...
Hi, Maybe somebody knows the answer to this. Is it possible to use different size pulley's on the same axis? If I where to use the Goto4all brackets.Is there...
YES. Just change the 495/497 "RA ratio" and "DEC Ratio" values. Use the magic number for the specific motor type, adjust that number for the non-1:1...
Thanks for the info, now that leads to another question :-)) is there a mathmatical fomula for working out the non 1:1 ratio? would this be using the diameter...
In our observatory i found a Meade 1200 electronic focuser model. it 's possible to use with a LX90 and 909 APM module? The 1200 Focuser has a jack compatible...
Hello Chaps! I'm new here, but I've been reading quite a bit about coverting the CG5/EQ5 mount to goto. Having just picked up a CG5 at a bargin price (well, I...
There is very little to choose in basic accuracy between the two. I had an EQ5 and found that the drives for that were OK for short exposure astro work. The...
Hi Alun, It is unlikely that basic tracking there will be much to choose between the two drive methods, however the GOTO route does open up one other ...
Thanks for the response chaps! I've jumped in and ordered the Meade#492 drives, so I guess I'm now committed (or should be!). My plan is to stip the CG5 over...
The precision is determined by several factors: mechanical (PEC, plays in many places, etc. in the mount), drive train (transmission slippage, and motor...
Thanks, I think I got all that! Would this also tie in with when you "train the motors" for the Autostar, allowing it to recognise discrepancies with the way...
Hi all, I have been watching this group with interest. I recently bought the brackets supplied by `goto4all`. They were a god-sent as I had kept on getting...
Alun, PWM = Pulse Width Modulation (a motor speed control method) I believe the Autostar "training the motor (unit)" is nothing but train the optical encoder...
For reference I have uploaded a picture of the DS motor with a brass gear fitted, you may notice that the final output gear on this motor is brass as well this...
John, From the picture, the 2 brass simple gears within the same compound gear seems to be separated by few mm or so. How are they connected? Thanks! ...
I can answer this for John, having seen one of the gear units. The compound gears are manufactured from a single piece of brass, but there is a gap between...
This info are very fresh. Pleasse look here: http://www.skywatchertelescope.com/EQ6SkyScan.html Skywatcher info: SkyScan Kit is available for upgrading the...
Fascinating. Looks like a first cousin to the Celestron NexStar controller with the menus moved around. Too bad it is a stepper system instead of a servo. ...
... http://www.skywatchertelescope.com/EQ6SkyScan.html ... (i note that the Polarscope is "Canada only"??) Er,... what's the -price-? looks like fun --dick...
I've just completed (mostly) the conversion of my Astroview 120 mount (an EQ3, I believe) to Autostar goto capability. I used the information here and that...
As always, I got these term confused. "Motor Calibration" is for the optimal opto-encoder setting, while "Train Drive" is to measure the encoder ticks vs....
I guess you have done all the obvious things. You have set your gear backlash settings by training the drive on a terrestial target, you have verified those...
Hi Tom: Thank u very much for the reply and the pics of your assembly and I can see wherer the EQ3-2 is very different, May I ask if you used the belt and the...
Walther, No, I did not use timing belts or pullies. I made shaft extenders and direct-coupled buth Meade DS gears directly to the RA and Dec axes. I made them...
