Re: New G11G Looking for final tweaking advice

 

Hi Nick,

Ha ha indeed (or was that H-alpha?!)

Seattle not on my calendar anyway, but...
if in California or Denver area of Colorado ....house calls may be possible....!

Generally the worm period of these mounts is quite long.? The G11 is shortest at 240 seconds.? ?The G11T is 319 sec, and the GM8 is at 480 sec.??

If the only oscillation is that or longer and hysteresis is short, then autoguiding normally solves all deep sky imaging issues.??

That's why the focus in this forum is usually on resolving any faster oscillations (gearbox at 32 sec [G11], worm bearings balls at 78 to 80 sec [G11]), and getting the hysteresis lag time (esp in DEC) as short as possible so PHD2 autoguiding can be effective and do it's magic.

Best,
Michael

So if I somehow fix this with the same fix, what should I expect to see in PEC Prep ? That spike to disappear into the noise I suppose ?

Do you ever stop by Seattle to visit ? haha I am likely to make things a whole lot worse if I start tinkering

Is there a way to analyze what kind of impact this actually has on images ??
