My AP400 GTO hand controller problem

Posted By Roland Christen
1) you are losing power at the 12 volt input connection to the servo box. The male connector has a center pin which is split (2 tines) Take a small bladed screw driver and gently spread the tines apart. This will allow the connector to make good contact with the female connector on the servo box.

2) If the resetting of the keypad takes you back each time to the start menu, then you have very old software in your keypad. You can update your software via download from our website. Doing so will eliminate the resetting to start menu.

Imaging with a long f refractor

Posted By Roland Christen
Yes absolutely you can image with this scope. I routinely image at F14.8 with a 10" and sometimes bump it up to F22 with a Barlow. A good stable mount is a must. It should have a low and smooth tracking error. You can also add a telecompressor on the back to get a bit more speed. Make sure it's a good one so you get the most out of your scope.

Some of them are Chinese made, or have Chinese optics.

NGC7635 The Bubble

Great start, but needs about 10x the exposure. Also camera looks slightly tilted. Make sure that the 4" adpater is seated square in the focuser.

1200 mount in Antarctica

Posted By Roland Christen
And here is the tracking graph for the mount - basically tracking sub-arc second in both axes for almost 1 hour, doing so at -60C in iced over conditions. That's a record for the 1200 mount.

artificial star test

Take a picture with your digital camera held up to the eyepiece, inside, outside and at focus. Like they did here in these tests (from 3rd one down): http://homepage3.nifty.com/cz_telesco/syoutenzoutest.htm

13 ethos vs. 13T6

Posted By Roland Christen
>>Well I'm seriously leaning toward the ethos plunge>>

It is futile to resist. Do not look through one because then you are lost for sure.

You have some beautiful colors and good detail. However I am not a fan of heavy diffraction spikes. Please forgive, but on objects like this it looks like car headlights seen through a screen door 8O
