I have had my GTO for about 16 years. The outer insulation on the cord to my remote control is crumbling when I move it. Can I just buy a new cord or do I need to purchase a whole new remote control?

I think I missed something. Why is Custom RA/Dec and Custom Alt/Az considered to be catalogues? Best regards, Niels Foldager

I agree with Kent. No need to get non-control info in the keypad. Jeff's original 3 suggestions, however, would be a useful feature, I think. Best regards, Niels Foldager

stars. In Great explantion, Roalnd. Thank you. To avoid confusion on this, would it be a good idea to change the name of "Sync" to, for example, "Orient"? That would signal that the function is not ju

I question the "Petri method" as I don't think it for sure can discriminate between the bell like oscillations (which we don't care about) and the bending oscillations. (Or can it? The frequency of la

Jeff: Of course Don is right, when he argues for as low mass as possible at the top of the pier. That is also the part of the pier where I would expect almost no bending to take place. For that reason

Hi Don, OK. But don't you agree that the amplitude will be smaller when the mass is increased? (for same impact) Best regards, Niels

Hi Don, Is this something that you know? The sand column inside is "bended" too, why I (and others) would expect energy to disappear in the sand. and lowers the amplitude (for a particular energy leve

Hi James, Thank you for your reply. I agree that there is no reason to fill concrete in the tube. However, due to the friction among the grains, sand has a good damping effect -- should you beat the t

James, Did you fill anything into the tube? Are you sure it is wise to weld it instead of bolt it? There is a danger that the plate will not be flat afterwards. Best regards, Niels Foldager

Thank you, Bruce. That would be most intersting. Best regards, Niels

Hi, Does a DSLRStar stand-alone unit work well for autoguiding on an AP 900GTO mount? Best regards, Niels Foldager

Are you sure where you moved? :-) Niels Foldager

Norm: I don't get your point. The display provides UTC (optionally modified with a timezone off-set). Of course UTC is the same wherever you are located. Best regards, Niels Foldager

I don't care about GPS on the mount. However, Rolando, listening to ones wife ... Best regards, Niels Foldager Denmark P.S. I do, however, use a handheld GPS as an acurate clock input for my laptop wh

Thank you so much to Eric, Konstantin, and Stuart! Best regards, Niels

Hi, I am preparing a special adapter plate to go on the declination head of my 900GTO (on the surface where you use to place a saddle plate.) We use the metric system in Denmark and I have not been ab

I want to attach my Takahashi TOA-150 refractor to my 900GTO. I could purchase an appropriate dovetail and a Losmandy saddle. However, the quick release is not important as this will be a permanent se

Thank you so much, Eric. link,

Roland, Sorry for my ignorance: Is lithium better than molybdenum grease? I don't know when one select the one for the other. Best regards, Niels Foldager
