I have an 8" LX200 with a 100mm f6 guidescope. I intend to use an autoguider on the guidescope while imaging with a CCD camera on the main scope. The guidescope alone weighs about 6 lbs. How much counterweight should I expect to need? Would the counterweight likely need to be located near the front or rear of the scope? Any suggestions on a good counterweight system that won't break the bank? Thanks in advance for the help! :bow:

Steve - You may find that shifting the position of the guidescope well forward provides counterbalance for the imager when it is attached. Unless you can come up with an adjustable platform for the guidescope and actually experiment with the weight distribution, and the suitability of the final position, it's going to be hard to predict where it will finally work out the best. If you decide you need a counterweight set, either the Meade or the Losmandy will be satisfactory; I suspect others will have some ideas for homemade solutions on the cheap. Regards - Graham

Thanks Graham,

I've never guided using a guidescope, only an off-axis guider. As a result I've never had much need until now to play around with the balance of the scope. I appreciate your suggestions and welcome any other input. Thanks again!

Steve ;)
