Don't put them on your observatory or house! -Christopher Erickson Observatory engineer Waikoloa, HI 96738 www.summitkinetics.com

I think there are a few really-important things to add about grounding. First, there are FOUR different types of grounding. 1. Electrical safety grounding. Fire and electrocution prevention. 2. ESD -

The Hotech collimator is VERY sensitive and it takes a bit of practice to set it up properly. I have two of them. I had one custom-made with a higher output power for a specialized application in a pr

If the RA axis motor wasn't moved at all during your experimentation and the servo controller never moved what it thought was the RA motor, then you would be good. However since you say that the wrong

If the servo controller has moved what it thought was the RA motor but in reality was the DEC motor, when it is hooked back to the RA motor, the RA worm drive assembly gears and worm won't be position

And just FWIW, now your PEM data is out of sync and its time to re-do your PEM curve. -Christopher Erickson Observatory engineer Waikoloa, HI 96738 www.summitkinetics.com

What kind of scope is your main scope? If it is a compound scope with a floating primary mirror, only off-axis or on-axis guiding will ever give best results. The only time I ever use piggyback guide

I would be curious about the total number of expected scopes versus the validated number of entries. Or at least the ratio. So as to get a better idea of our odds. -Christopher Erickson Observatory en

Generally speaking, the softer the material is, the courser the threads should be. -Christopher Erickson Observatory engineer Waikoloa, HI 96738 www.summitkinetics.com

If spreading the power center pin doesn't make the hand controller behavior better, my bet is that a new coiled handset cord will improve the handset's behavior. "Always take the high road. There's le

The problem is in the limitations of your dome's controller software driver and that is where it should be fixed by the software developer. Neither APPC or ASCOM is the correct place to deal with this

And of course the classic IP address conflict, where two devices are trying to use the same IP address for some reason. Either having two DHCP servers running or having a static configuration in the C

Ethernet connection or something wonky going on in the communications over the ethernet network. A layer-2 or layer-3 broadcast storm of some kind can cause network congestion and lost Ethernet frames

APCC never talks to the dome driver or sends commands to it. The dome driver regularly queries the current mount position in ASCOM-land and then slaves to that pointing location. The dome driver doesn

I love that too. In my job, I need to access serial port consoles all the time on motor control systems, routers, etc. -Christopher Erickson Observatory engineer Waikoloa, HI 96738 www.summitkinetics.

I have been experimenting with GPD Windows micro-laptops (Palmtops re-invented?) for image and occultation capture. They are about the size of a typical NUC but have a real screen, keyboard and touchp

When I had my 900, I brought the cables back closer to the Dec axis and let them hang down from there. "Always take the high road. There's less traffic." -Christopher Erickson Observatory Engineer Sum

1. I have the flat surface adapter bolted to the Losmandy HD Tripod. The mount is secured to this adapter with 6 bolts that can be inserted with a hex key. This is OK, but I am mobile and was thinking

For anyone who wants to travel to the Big Island, I have plenty of mounts and OTA's that I am willing to loan or rent to anyone coming here. I am willing to loan some small scopes and mounts. Stuff 8"

Putting the gearbox back on with a different point on the RA wheel gear against the RA worm gear won't mess up your PEC curve. PEC is all about the worm gear position, not the worm wheel gear position
