Question: Can this be used with an autoguider? I don't see an guideport port, so I imagine not? Thank you!
Document: The system seems to be working very well so far. I would have preferred they used stainless steel or aluminum for the bracket which holds the RA motor to the base. I liked the clutch used on the DEC motor but wish there was one on the RA motor. The only way to slew fast is by releasing the main brake on the RA axis and this movement is hard to control precisely. If there was a clutch on the motor like the DEC one then you could use the control knobs which turn the worm gear for a more precise control.
Also, I taped the wires together part way up from the hand controller to help eliminate tangling. The motors are very quiet. I had to put my ear up close to hear if they were running. I used alkaline D cells to power it but I plan on trying high capacity rechargeable NiMH batteries. I am not sure if the voltage drop will make any difference in the tracking rate. If the rechargeable batteries work good at initial charge they should provide better tracking stability than alkaline batteries since the voltage drops off very little on NiMH batteries right up to the end.
On the camera itself I have a telephoto lens, and a 3.0 neutral density 1000x filter, and I'm shooting at 1/8000s with f/9.6. You can easily see sun spots in fair detail and if the eclipse is any indication, the final video will come out very nice.The motor mounts are a necessity for an equatorially mounted tripod, and once all the said and done, this setup is a fraction of the cost of many other equatorial mounts, and it is very well built.
Mechanically the unit seems to work quite well. The gear on the DEC axis didn't perfectly align but still works. The buttons sometimes take a second or 2 to respond probably due to the scope not being balanced perfectly. There are 3 speed selections. 2x, 4x, and 8x. It automatically starts tracking when you turn it on at 1x. That should be good enough. The better the scope is aligned the better this will work but so far I haven't been able to see anything without a little drift. Not the fault of this motor drive.
I just placed an order to replace the motor I have on my scope.Don't ask what happened to the last one.I am a bit physically challenged and this motor made my viewing sessions much much smoother. I like being able to climb down, get a different eyepiece and still have the object centered by the time I climb back up.The other item that I think every back-yard viewer should have is a telerad.I can't imagine giving either accessory up.Sally
I would also have appreciated some kind of hanger clip on the hand control box so it could be hung from some spot on the tripod. I will have to invent this myself.
Next, I intend to get a nice telescope to mount on it and get some star gazing done.Back to check on the transit...Here is the video taken with this equipment: [...]
I commented on this review with a link showcasing the best images I was able to take on my CG-4 with the motors bought here. Even though i've moved on to a bigger mount, I would still recommend this product in a heartbeat.
Very nice addition to my rig. I've been using the CG4 and motor for a few months now, for astrophotography mainly. The tracking is perfect, and I have been able to take 30+ second exposures with no problems or unwanted movement whatsoever. Very smooth and very reliable. It has been an indispensable piece of equipment for me, and I would definitely recommend it.
I purchased this for my CG 4 Mount and it works exactly as described. One thing to know if the battery start running low it will fall slightly behind. I wound up with that DC adapter &#8211; second small battery in order to keep it tracking properly for astrophotography. Over all I am pleased with my purchase.
Answer: The answer is mostly no but if you are willing to do a little soldering you can instal a port for the auto-guider. i saw instructions for this mod online.
